How to remove the battery from a Volkswagen Polo sedan

Russian winters are the coldest and most merciless natural phenomena. Even technology sometimes fails, bending under the pressure of 30-degree frosts. Probably the only country that could withstand the attacks of the futuristic conquering machines shown in science fiction films is Russia. Any robot would simply turn into a useless piece of hardware: the battery would run out in no time.

So our motorists suffer from severe weather conditions every winter. They will sit in the yard early in the morning, open the hood and wait for friends or relatives to arrive and give them a good “light.”

However, a cold winter is only a catalyst for the problem. After all, he knew that the battery was already old and practically no longer held a charge. I wanted to change it in the summer, buy a new one and close the issue. But they didn’t get around to it. And now you jump from foot to foot in an attempt to warm up - punishment to the fullest extent of an impassive case.

Typically, the service life of a car battery is about 5 years (provided that the resource is consumed wisely and without naive “procrastination” like “forgot to turn off the headlights when leaving the car overnight”).

The rapid wear of the device can also be caused by mechanical damage such as cracks in the housing through which electrolyte leaks. If the problem is a malfunction, then it would be best to replace the broken battery with a fresh one. Attempts to “resurrect” the device are not a very good option for further successful operation of the car. The chemicals that fill the battery space are very caustic. If they damage the vital components of the car, then the car owner will have to replace not only the leaking “culprit”, but also all the damaged equipment under the hood.

Wherever the famous German Volkswagen Polo sedan is assembled, the same spare parts are used in all variations of the car. Including the battery.

How to remove the battery from a Volkswagen Polo sedan video and video review

The hood rises above the engine compartment.
The latches securing the fuse box are retracted to the sides. Use a 13mm wrench to unscrew the bolt and remove the battery mounting bracket. The battery is removed from the seat. The protective rubber cover is removed from the used battery and placed on the new battery. The new battery is installed in place and secured with a bracket. The fuse box returns to its place, the wire tips are fixed in the battery terminals.

In order for the window regulators to restore their operation, you need to lower the windows, raise them all the way and hold the key pressed for a couple of seconds.

Dimensions are also critical for selection. Basic parameters of batteries for VW Polo To crank the crankshaft of a cold engine, significant force is required through the starter.

This is the starting current for batteries installed at the plant in Kaluga. When the time comes for replacement, it is better to purchase a battery with a starting current of up to amps. The batteries must have an impressive reserve of capacity so as not to discharge after several unsuccessful starts in a row in frosty weather.

Replacing the battery for a Volkswagen Polo sedan

Powerful gasoline and diesel engines require a lot of effort when starting. Therefore, for such power units, batteries in the same capacity range, but with a starting current of up to amps, are better suited.

The following article will help you deal with this issue, including a video explaining how to remove the battery from a Volkswagen Polo sedan. The removal process is quite simple and can be done by a novice car enthusiast with minimal skills in handling the tool. Moreover, no highly specialized tools are required and they can be found in any standard set.

Simple and brilliant. You can charge the battery with any car charger, of which there are now ten types in any store. Of course, automatic ones, with current and voltage stabilization, are preferable, but taking into account the fact that the average car owner charges the battery no more than once a year, then any will do. If the battery is deeply discharged, to zero, then set yourself up for a day, no less.

But if you just need to start the car on a frosty morning and a couple of crankshaft revolutions are not enough, then there is a trick you can do without charging at all. Place the battery in the heater, and in half an hour it will start your car without any problems. For a Volkswagen Polo car, many experts recommend using a lead-acid battery, the action of which is based on the contact of lead, oxide and sulfuric acid.

There are two types of such batteries: Serviceable, these are products that have holes on the top cover, closed with blind plugs.

If necessary, they can be removed and the density of the electrolyte can be measured using a hydrometer. Also, distilled water that has evaporated during operation can be added to such a battery.

Units not serviced. So our motorists suffer from severe weather conditions every winter. After all, he knew that the battery was already old and practically no longer held a charge. I wanted to change it in the summer, buy a new one and close the issue.

But they didn’t get around to it. The rapid wear of the device can also be caused by mechanical damage such as cracks in the housing through which electrolyte leaks. If the problem is a malfunction, then it would be best to replace the broken battery with a fresh one. The chemicals that fill the battery space are very caustic.

Volkswagen polo battery

Wherever the famous German Volkswagen Polo sedan is assembled, the same spare parts are used in all variations of the car. Including the battery.

Tips and recommendations for choosing a battery Which unit should you buy? For replacement, you can take both the original device and its analogues.

There is a whole abyss of devices of various brands and technical parameters on the market. Anyhow, it’s not worth buying. Therefore, you should carefully study the characteristics of your battery. The Polo sedan has a conventional battery with a nominal voltage of 12V. This indicator is used in all passenger cars. Today such devices are installed on light equipment.

Correctly charging a car battery

These are safety rules and it is better not to joke with it. When the ground is disconnected, you will not set off fireworks by dropping the key on the positive wire. By the way, the striped one has one of the most convenient terminals I have ever seen in my life; it is very easy to clamp and release. And the nut looks up, and not to the side, it is easy to turn it with the butt end:. We unscrew the above nut next to the positive terminal, but the fuse block remains on the battery and has two more latches on the sides.

We pry them with our fingers:

And we pull up. Do this carefully in the cold, the plastic becomes brittle! The block comes off almost effortlessly. Here it is, separately:. Next, using the same 10-point end, open the positive terminal and remove it, just like the ground.

Now it’s the turn of the battery itself. It is secured with a 13 mm bolt and a pressure plate. Like this:. These channels, in case the battery leaks, so that the acid does not eat half of your front, and glass into this hole:.

You can charge the battery with any car charger, of which there are now ten types in any store. Of course, automatic ones, with current and voltage stabilization, are preferable, but taking into account the fact that the average car owner charges the battery no more than once a year, then any will do. If the battery is deeply discharged, to zero, then set yourself up for a day, no less.

Step by step replacement

But if you just need to start the car on a frosty morning and a couple of crankshaft revolutions are not enough, then there is a trick you can do without charging at all. Place the battery in the heater, and in half an hour it will start your car without any problems. But this does not exclude the need to recharge it in the evening, otherwise the next morning the same thing will happen. It must be periodically monitored using an ammeter on the charger.

The voltage at the terminals should not exceed 14.4 volts. During charging, the voltage will increase and the current will decrease. If the current does not decrease during the last hours, then the battery is considered charged. Have you charged the battery? We put everything back in the same sequence. Lastly, connect the ground, don’t forget. As a result of removing and installing the battery, my clock was reset on the Comfortline configuration. That's the only thing that happened. Do you know how to set the time?

Well, read the manual, it says there. However, if you have a fully minced Highline, then there are several nuances. There is no need to be scared; it will go out on its own when you move.

To speed up the process, you can turn the steering wheel left and right several times at the beginning of the movement so that the steering column position sensors turn on. Secondly, the cool RCD radio is rumored to be locked for anti-vandal purposes and ask for a code.

Determining the malfunction

If starting is difficult, it is necessary to measure the voltage value; for this, use a voltmeter or tester. The voltage should be no more than 12 volts when the voltage is off.

If the voltage indicator does not correspond to the required value, it is necessary to find out the reason; if the battery is to blame for this discrepancy, then replacement is necessary.

A faulty battery can also be determined by the following signs:

The engine does not start, despite the battery being fully charged, this is especially pronounced in winter. This means that the starting current is low. It is not enough to fully spin up the starter.
If the engine has not been running for a long time, it will then be impossible to start. This indicates that the battery is being discharged due to a significant drop in its capacity.
The battery does not charge or is charged too quickly.

Before removing the battery from the Volkswagen Polo sedan, make sure that these signs are present and that there is a discrepancy in voltage values.

The battery is not at all difficult to replace. This task is easy to complete even for beginners.

To do this you need to have:

wrench 8x10;
extension cord with inserted head for 13;
slotted screwdriver.

Replacement must be done in this order:

the hood of the engine compartment rises;
remove the tip with the wire inserted into it from the “-” terminal of the battery;
after lifting the cover, it is necessary to loosen the tip attached to the positive terminal of the battery;
the latches of the safety block are unfastened;
the tip with the positive wire is removed from the battery along with the fuse block attached to it;
unscrew the bolt using a 12x13 wrench, then you need to remove the battery fasteners;
the battery is removed from its seat without any interference;
the protective case must be removed from the old device, and then it is used with the new battery;
the new battery is placed in its seat and secured with a bracket;
The fuse box also returns to its place.

After replacing the battery device, you will need to reset the clock, and unlocking will be necessary to restore the radio. If the VW Polo is equipped with an automatic transmission, and it is more often equipped with an automatic transmission, the factory settings will be restored, and immediately after the start of operation, jerks may be felt when changing gears. They will subsequently disappear as soon as the automatic transmission adapts.

It will also be necessary to adjust the operation of the window regulators.

How to properly remove the battery from a car

It can often happen that when you try to start your car in the morning, you get the opposite result to what you expected. Whether the reason is the headlights burning all night or the capacity reduced due to age, the result is disappointing - the battery is discharged.

To replace the battery or simply charge it, you must first remove it. The following article will help you deal with this issue, including a video explaining how to remove the battery from a Volkswagen Polo sedan. The removal process is quite simple and can be done by a novice car enthusiast with minimal skills in handling the tool. Moreover, no highly specialized tools are required and they can be found in any standard set.

Before starting work, it is important to make sure that the ignition is turned off in order to avoid unpleasant situations that could completely damage the battery. Having prepared the necessary tools and opened the hood, you can get to work.

Next, the protective cover is removed from the battery. After completing all the steps described above, you can remove the battery itself. By removing the battery, you can access its mounting shelf and cables for maintenance. To remove the mounting shelf, you need to unscrew the three bolts securing the shelf to the body. Upon completion of maintenance, assembly is carried out in the reverse order. Using these simple steps and the simplest tools, you can independently carry out all the necessary work on servicing your car’s battery.

How to remove the battery from a Volkswagen Polo sedan video

You can remove the battery from a Volkswagen Polo hatchback using the same steps - the mounting design is no different from that in a sedan. I’m going on vacation for a month and since it’s winter outside, I think it wouldn’t be a bad idea to remove the battery and leave it warm at home. I read how this should be done and what consequences may arise in an article from user treon on the polo-sedan website. Unfortunately the pictures did not open. People tell some horror stories about batteries. What have I not heard enough!

Do not remove the terminal on the injector! Generally not possible! Yeah, that's right - the Fierce Nightmare will come immediately - the doors will close, the wheels will fall off and the gas tank will explode. Well, let's be logical!

The battery is a consumable and needs to be replaced occasionally. And why do you think the car immediately becomes unusable?

Nothing like that. There is nothing to do at all to install the battery. On our Polo sedan, for example, in addition to the obvious method of forgetting the dimensions, it is enough to leave the car unlocked with the central lock. I don’t know why this was invented, but when the locks are open, the current consumption is noticeably higher; this is somehow connected with the sleep mode of the ECU.

I parked the car in the garage, went on vacation for a week, and you arrive and it’s a big deal. And in winter, it’s a nice thing to spend a day in traffic jams with a stove, headlights and heating everything, frost at night, in the morning the starter oo-oops And still no one is going anywhere.

And what? Will you call a tow truck and take it to the dealer service? Or will you still remove the battery and take it home to recharge? If you still choose the second option, then removing the battery for a Polo sedan is especially for you. Drumroll, let's go!

My fellow owners were tormented by asking what kind of box is on top of the battery, and how do I even remove it? I explain to everyone right away that this is a power fuse block. If you pick off the cap, it will look like this: This is not instead of, but in addition to those fuses that are in the cabin. Mighty security forces per amp. All power goes through them, and if even one burns out, no one will go anywhere. But now we are not interested in fuses, but in the battery.

Therefore, we do not remove the cap from them, but instead remove the cap from the positive terminal. Here she is:. That's what we need! That is, in fact, you can unscrew the terminal and pull it off together, but this is inconvenient. In general, as a note to the housewife, we always turn off the mass first, not the plus.

Choosing a storage device for a Volkswagen Polo car

The battery plays an important role in the functioning of the Volkswagen Sedan.,

Without it, the engine will not start, and electronic devices cannot be turned on. Even the alarm won't beep. This model must have a storage device installed with the following parameters:

The battery must be of reverse polarity, that is, have a right positive;
meet the European standard - 60–64 Ah;
the starting current must be at least 540 A;
the presence of a lower side is mandatory, since in this model the battery is secured using this side;
The dimensions of the storage device must have the following parameters:
width—175 mm;
height—175 mm;
length—245 mm;

Determining the quality of a battery

The quality of the battery must meet many parameters.

Let's look at the two main characteristics:

Durability of the device. It is determined by the ability of the battery to maintain its basic properties for an estimated time. When the vehicle is moving, the battery is automatically recharged. Therefore, it practically does not discharge. When the battery has completely exhausted its potential resource, it must be replaced. The average estimated operating time of storage devices must be at least three years.
The amount of current that comes from the starter. The most important purpose of the battery is to start the engine. When the ignition key is turned, the storage device must supply an electrical current to the starter, which starts the engine. The motor starting current is the number of amperes generated in half a minute. This indicator is not constant; when operating at low temperatures, it always becomes lower. The optimal value is considered to correspond to more or less starting current if the ambient temperature is 27 degrees. For a Volkswagen Polo model car, this figure is 260 A. The less it changes at different temperature conditions, the better the storage device is considered.

Battery for Volkswagen Polo

You can remove the battery from a Volkswagen Polo hatchback using the same steps - the mounting design is no different from that in a sedan. Therefore, we do not remove the cap from them, but instead remove the cap from the positive terminal. In addition, some Volkswagen Polo batteries produce batteries with reduced-size leads of a different standard, which also cannot be connected to the on-board network of your car.

You can remove the battery from a Volkswagen Polo hatchback by performing the same steps - the mounting design is not...

For replacement, you can take both the original device and its analogues. Unscrew the nut on the terminal and remove the wire.

The block comes off almost effortlessly.

It is advisable to choose for your car, taking into account the recommendations of the manufacturer, a maintenance-free battery from a wide range of car batteries from various manufacturers represented on the car spare parts market. It must be remembered that at low temperatures, due to an increase in the viscosity of the engine oil and worsening fuel ignition conditions, the power consumed by the starter when starting the engine increases two to three times.

In some cases, the starting time of a cold engine compared to a warm one increases by several times. Still others say that the effect becomes noticeable when the speed reaches the mark and above, which is a high indicator for normal driving.

Be that as it may, charging occurs both at idle and at high speeds.

Another thing is that the charging speed will be different in both cases. The second method guarantees that the battery is fully charged.

If the light indicating the battery lights up on the dashboard after starting the engine, then there can only be one problem. It is mainly due to the improper functioning of the generator.

However, as soon as you get on the road and pick up speed, the indication disappears. This behavior can be explained by the fact that the current in the generator increases, which is transmitted to the battery, that is, the connection between two interdependent links increases.

Once this connection weakens, the light bulb lights up again. Problems with the generator can occur in different parts of the element. Now I found out with a multimeter on the plus and minus, there is a discharge, I have already found the circuit. Thanks for the advice, I'll find it using fuses.

If you change it immediately after disconnecting the minus, the current will undoubtedly be greater than ma.

And for example, it is possible that it is not the door at all, but the right pillar. Loosen the fastening and remove the electrical conductor plate from the positive terminal of the battery, see.

If present, open and remove the thermal protective cover of the battery, indicated by the arrow. At the bottom of the battery, unscrew the bolt indicated by the arrow and remove the battery mounting plate.

Move the battery to the side, while releasing the fastening of the second side of the battery and remove the battery from the engine compartment. If the battery is deeply discharged, to zero, then set yourself up for a day, no less. But if you just need to start the car on a frosty morning and a couple of crankshaft revolutions are not enough, then there is a trick you can do without charging at all. Place the battery in the heater, and in half an hour it will start your car without any problems. It must be periodically monitored using an ammeter on the charger.

We choose and independently change the battery of a Volkswagen Polo sedan

Typically, the service life of a car battery is about 5 years (provided that the resource is consumed wisely and without naive “procrastination” like “forgot to turn off the headlights when leaving the car overnight”).

Wherever the famous German Volkswagen Polo sedan is assembled, the same spare parts are used in all variations of the car. Including the battery.

Tips and tricks for choosing a battery

Which unit should I buy? For replacement, you can take both the original device and its analogues. There is a whole abyss of devices of various brands and technical parameters on the market. Anyhow, it’s not worth buying. Therefore, you should carefully study the characteristics of your battery.

Firstly, it is important to be aware of voltage. The Polo sedan has a conventional battery with a nominal voltage of 12V. This indicator is used in all passenger cars. Until the 1940s Six-volt batteries for cars were mainly used. Today such devices are installed on light equipment. There are also 24V batteries. They are mounted on heavy special equipment and trucks.

Secondly, the capacity of batteries may vary. It is measured in ampere/hours. Information about the volume is usually indicated on a special label or in the operating instructions for the device. What should be the standard capacity for passenger cars? Usually it is limited to the range 50−60A/h.

It is best to take a battery with the same parameter as on the old unit. After all, each model has its own characteristics. If you install a battery with a large capacity, it will not charge completely. Conversely, a battery with a lower capacity will recharge quickly. Both options offer a not entirely positive outcome associated with the breakdown of the device. The capacity of the factory battery on the Volkswagen Polo is 60A/h.

Thirdly, dimensions play an important role. The battery must have the appropriate length, width and height. Otherwise, the device simply will not fit under the hood of the car. Dimensions of the sedan battery: length - 207 mm, width - 175 mm, height - 190 mm.

Fourthly, you need to pay attention to the location of the terminals. In domestic cars, mostly straight polarity is installed (plus - on the left, minus - on the right). Foreign cars may have reverse polarity (for example, Japanese car models). Since the standard wiring suitable for the “minus” and “plus” has a limited size, the wires simply will not reach the terminals. In this case, only extending the wires will save you. For the Polo sedan, the polarity is reversed.

Finally, the last thing you should ask your sales consultant about when choosing a battery is the date of manufacture of the device. The official date from which the service life is counted is considered to be the moment the electrolyte is poured at the factory. Therefore, when purchasing, it is important to monitor the “life” of the battery.

Which battery model is ideal for replacement?

The “budget” version of the battery for the sedan is an original spare part from VAG with code 000915105de. A battery is considered “budget” because the cost of a copy in online stores is estimated at 7,500 rubles. In principle, you can choose cheaper analogues, but on the Polo sedan it is best to use either the originals or high-quality expensive installations with the same data.

An expensive option is a device with a 12-volt battery with a capacity of 60A/h and a current of 280A. At Exist, the cost of the device approaches the 10,000 ruble mark.

Another possibility is to purchase a sample from “brothers” in the model range. For example, from a Golf or Tiguan: a battery with parameters 61A/h and 330A, code number JZW915105, costs around 3,500 rubles, and a unit JZW915105A with 72A/h and 350A will cost under 5,000 rubles.

We must also not forget that a clamping bar may be needed under the battery. For the original it is worth buying 6X0959502A, if you look at the VAG catalog.

Installing a new unit is an excellent job, guaranteeing high quality operation of all electrical components of the car. What should you do if the battery is completely new, but there was a “mistake” and the battery is completely dead? There is only one way out - charging the battery.

Original and analogues

VW Polo cars are equipped with batteries from the German company Varta. Their characteristics:

capacity: 60 Ah;
dimensions: 242 by 175 by 190 (175) – dimensions in millimeters;
starting current: 550 – 650 A;
polarity: reverse.

If you have any doubts during the selection, use the catalog numbers (articles): If you have any doubts during the selection, use the catalog numbers (articles):

566047051;
560410054;
561400060;
560408054;
563400061;
560409054;
560901068.

This way you definitely won’t go wrong with a specific battery model. However, you can install a battery from another manufacturer in your car. Basic conditions: compliance with technical specifications. If you “fly” with the dimensions, the battery simply will not fit into the seat intended for it.

When purchasing, it is allowed to install batteries with increased power up to 65 Ah, but no more. With a capacity exceeding 70 Ah, the generator is overloaded and the battery is undercharged, which negatively affects both its service life and starting performance.

Of the equivalents, the best are Bosch batteries with catalog numbers:

0092S40040;
0092S50040;
0092S4E050;
0092S40050;
0092S50050.

You can also use batteries from other manufacturers: Mutlu, Tymen Battery, Exide. Since all batteries are produced with standard parameters, it all depends on the owner’s wallet: the cheaper the battery, the more potential problems there will be with it.

Battery replacement instructions

Replacing the battery on a sedan is a simple process. For the procedure, you will need a key with two heads: “10” and “13”. Sequencing:

Turn off the ignition and open the hood.
Loosen the nut on the tip of the minus terminal and remove the wire from it.
Remove the cover from the plus terminal.
Unscrew the nut on the terminal and remove the wire.
Remove the fuse block and inserts from the battery.
Remove the clamping plate mounting bolt and remove the bar.
Remove the protective cover.
Remove the battery.
Reassemble everything in reverse order, close the hood and turn on the ignition.

Before connecting the wires, clean the terminals and lugs with sandpaper. After connection, it is recommended to apply a small layer of copper-containing grease to the surface.

Most of the parameters that were in the computer's memory will be erased. Therefore, we reset the time on the scoreboard. During the first kilometers the car will undergo adaptation: the automatic transmission will twitch. Over time, the “jerks” will stop.

The lamp responsible for the vehicle stabilization system may also turn on. Don't panic: it will automatically go out after a couple of kilometers.

The battery removal diagram may be useful for those who decide to take the device for repair or charging. With the battery removed, only one question arises: how to close the doors?

The instructions are quite simple:

We use the key fob to open the car doors.
We sit in the salon and close the door.
For the on-board computer to work correctly, turn on the ignition for a couple of seconds.
Turn off the ignition, do not remove the key.
Press the central locking button and close all doors. Thus, all doors will be closed, but the alarm will not work.
We press the handle on the driver's door and open it.
Unlock the hood.
We remove the battery according to the diagram above.
Close the hood.
Use the key to close the driver's door.

All is ready. The plan is put in order: the doors are closed, and the soul does not have to worry about the safety of the car.

Step by step replacement

1. Loosen the nut securing the negative terminal of the battery.

2. Lift the plastic cover and loosen the nut securing the positive terminal of the battery.

3. Remove the negative and positive terminals.

4. Use your finger to lift the lever towards you. With this action we remove the power fuse block along with the positive terminal, which we removed in advance. I advise you to watch this in the video lesson.

5. Using a 13mm socket, unscrew the battery bracket bolt and remove it.

6. Nothing holds the battery anymore, remove it.

7. Remove the rubber casing from the old battery and replace it with the new one.

8. Mount the battery in place and secure it with a bracket.

There is a bend on the bracket; after tightening the bolt, the bend should press against the side of the battery. The photos below show everything.

9. We put on the positive terminal; it goes together with the power fuse block.

10. Tighten the nut securing the positive terminal and snap on the plastic cover.

11. We put on the negative terminal and secure it with a nut.

Basic information about batteries installed in Volkswagen Polo

The main functions of a modern battery are:

start the car engine;
ensure the operation of all lighting devices, multimedia systems, locks and security system when the engine is turned off;
replenish missing energy from the generator during periods of peak load.

For Russian motorists, the issue of starting the engine during the frosty winter is especially relevant. What is a car battery? This is a device that converts the energy of a chemical reaction into electricity, which is required to start the engine, as well as when it is turned off. At this time, the battery is discharged. When the engine is started and begins to work, the reverse process occurs - the battery begins to charge. The electricity generated by the generator is accumulated into the chemical energy of the battery.

Battery device

A classic battery is a container filled with liquid electrolyte. Electrodes are immersed in a solution of sulfuric acid: negative (cathode) and positive (anode). The cathode is a thin lead plate with a porous surface. The anode is a thin mesh into which lead oxide is pressed, which has a porous surface for better contact with the electrolyte. The anode and cathode plates are very close to each other, separated only by a layer of plastic separator.

A car battery has 6 assembled blocks (sections, cans) consisting of alternating cathodes and anodes. Each of them can produce a current of 2 Volts. The banks are connected in series. Thus, a voltage of 12 volts is generated at the output terminals.

Video: how a lead-acid battery works and works

Types of modern batteries

In cars, the most common and best-priced batteries are lead-acid. They differ in manufacturing technology, physical state of the electrolyte and are divided into the following types:

SLI is the most common type and the classic one. The electrolyte in such batteries is a liquid mixture of distilled water and sulfuric acid. Such batteries are installed in the Volkswagen Polo during factory assembly. The main disadvantages of such batteries are:
Negative effects of temperature changes.
Deterioration of performance due to vibration and other mechanical influences.
EFB is an improved version of SLI. The difference is in thicker plates packed in special microfiber. The service life and characteristics of such batteries are better than those of classic ones, but they are also more expensive.
AGM - the space between the plates is filled with fiberglass, which is impregnated with electrolyte. These batteries are no longer afraid of deep discharges, charge quickly and are capable of delivering high starting current. Not afraid of strong vibrations. VAG installs batteries of this type on the latest generation vehicles equipped with engines with a Start-Stop system. The cost of such batteries is higher than SLI and EFB.

Any of the above types can be installed on a VW Polo if its main characteristics coincide with those stated in the service book.

The manufacturer installs a maintenance-free battery on vehicles with a nominal voltage of 12 V and a capacity of 60 Ah. The battery elements are located in a polypropylene monoblock and are closed by a common cover, inseparably connected to the monoblock. There are no plugs in the battery cover, since topping up with distilled water is not required. Two vents allow the small amount of gas generated in the battery to escape to the outside.

A modern car is full of various electrical consumers and electronic devices, from the audio system to electronic engine control system units, gearboxes, anti-lock brakes, airbags, etc. In the damp off-season and especially in winter, all automotive electrical and electronics, primarily the automobile battery, are tested for endurance.

Expiration date, maintenance and battery failures

The service books that come with VW Polo cars do not provide for battery replacement. That is, ideally, the batteries should work throughout the entire service life of the car. It is only recommended to check the battery charge level, as well as cleaning and lubricating the terminals with a special conductive compound. These operations must be performed every 2 years of vehicle operation.

In reality, the situation is somewhat different - the battery needs to be replaced after 4-5 years of operation. This is due to the fact that each battery is designed for a certain number of charge-discharge cycles. During this time, irreversible chemical changes occur that lead to loss of battery capacity. In this regard, the main malfunction of all batteries is their inability to start the car engine. The reason for the loss of capacity may be violations of operating rules or exhaustion of the battery life.

Replacing the battery in a Volkswagen Polo

A healthy battery should start the engine quickly in a wide temperature range (from -30 °C to +40 °C). If starting is difficult, you need to check the voltage at the terminals using a multimeter. When the ignition is off, it should exceed 12 volts. While the starter is operating, the voltage should not fall below 11 V. If its level is lower, you need to find out the reason for the low battery charge. If this is the problem, replace it.

The battery is easy to replace. Even a novice motorist can do this. To do this you will need the following tools:

key to 10;
head 13 with extension;
slotted screwdriver.

Before removing the battery, turn off all electrical appliances in the cabin. If you disconnect the battery, you will then have to set the clock again, and to turn on the radio you will have to enter the unlock code. If there is an automatic transmission, its settings will return to the factory settings, so at first there may be jerks during gear changes. They will disappear after adapting the automatic transmission. It will be necessary to re-adjust the operation of the power windows after replacing the battery. The work is carried out in the following sequence:

The hood rises above the engine compartment.
Using a 10mm wrench, remove the wire tip from the negative terminal of the battery.

In order for the window regulators to restore their operation, you need to lower the windows, raise them all the way and hold the key pressed for a couple of seconds.

What batteries can be installed on Volkswagen Polo

Batteries are suitable for vehicles based on the types and power of engines installed on them. Dimensions are also critical for selection. Below are the characteristics and dimensions by which you can select a battery for any of the Volkswagen Polo modifications.

Basic parameters of batteries for VW Polo

To crank the crankshaft of a cold engine, significant force is required through the starter. Therefore, the starting current in batteries capable of starting the Volkswagen Polo family of gasoline engines must be at least 480 amperes. This is the starting current for batteries installed at the plant in Kaluga. When it comes time for replacement, it is better to purchase a battery with a cranking current of 480 to 540 amps.

The batteries must have an impressive reserve of capacity so as not to discharge after several unsuccessful starts in a row in frosty weather. The battery capacity for gasoline engines ranges from 60 to 65 a/h. Powerful gasoline and diesel engines require a lot of effort when starting. Therefore, for such power units, batteries in the same capacity range, but with a starting current of 500 to 600 amperes, are better suited. For each modification of the car, a battery is used, the parameters of which are indicated in the service book.

In addition to these characteristics, the battery is also selected according to other parameters:

Dimensions - the Volkswagen Polo must have a European standard battery installed, 24.2 cm long, 17.5 cm wide, 19 cm high.
The location of the terminals should be the right “+”, that is, the battery with reverse polarity.
The lip at the base is necessary so that the battery can be secured.

There are quite a few batteries on sale that are suitable for the VW Polo. When choosing, you need to choose a battery that has the closest performance to those recommended in the VAG service book. You can install a more powerful battery, but the generator will not be able to fully charge it. At the same time, a weaker battery will quickly discharge, due to this its resource will end faster. Below are inexpensive Russian and foreign-made batteries that are available for Volkswagen Polo with diesel and gasoline engines.

Which battery to choose

The modern market offers many types of batteries, both in size and type of working substance. For a Volkswagen Polo car, many experts recommend using a lead-acid battery, the action of which is based on the reaction of lead, oxide and sulfuric acid during contact. There are two types of such batteries:

Serviceable products are products that have holes on the top cover closed with blind plugs. If necessary, they can be removed and the density of the electrolyte can be measured using a hydrometer. Also, distilled water that has evaporated during operation can be added to such a battery.
Units not serviced. In this case, it will not be possible to carry out accurate diagnostics and measurements, since the battery case is completely sealed, and there are only small holes on its cover to allow the accumulated gas to escape.

The operation of both of the above types of batteries is no different; the difference lies only in the ability to service the product and carry out minor repairs.

As a rule, the cost of a closed battery is slightly lower than its counterpart, but its service life is on average 15-20% shorter than that of a serviced one.

We select and independently change the Volkswagen Pol sedan car battery

Russian winters. the coldest and most merciless natural phenomena. Even equipment sometimes breaks down, bending under the pressure of 30-degree frost. Probably the only country that could resist the onslaught of futuristic car conquest by pretending to be in sci-fi movies. It's Russia. Any robot will simply turn into useless hardware: the battery will be discharged twice.

This is why our motorists suffer from severe weather every year. While running around the yard early in the morning, they will open the hood and wait for friends or relatives to arrive and provide the necessary light.

However, cold winters are only a catalyst for the problem. in conclusion , He knew that the battery was old and there was practically no charge. I wanted to change it in the summer, buy a new one and close the issue. But my hands did not reach me. And now you're jumping from one foot to the other, trying to stay warm. punishment with all the severity of a fearless deed.

Typically, the battery life of cars is about 5 years (provided that the resource is used wisely and without naive “delay”, like “forgot to turn off the lights when leaving the car at night”).

Mechanical damage, such as cracks in the housing through which electrolyte leaks, can also cause rapid wear of the device. If this is a malfunction, it is better to replace the damaged battery with a new one. Attempts to resurrect the device. This is not a good option for the further successful operation of the car. The chemicals that fill the battery compartment are very aggressive. If they damage vital parts of the car, the car owner will have to replace not only the culprit, but also any damaged equipment under the hood.

Wherever the famous German Volkswagen Polo sedan is assembled, the same parts are used in all variants of the car. Including battery.
