Selection and replacement of the battery on a Ford Focus car

Before installing the battery, do not forget to clean the terminals and tip surfaces (from the inside). This can be done with fine sandpaper. Do not mix up the wires when connecting. After connecting the wires to the battery, lubricate the exposed parts of the terminals and the metal ends of the wires with a thin layer of grease (or something similar).

I think there are no more questions with the question of how to remove the battery from a Ford Focus 2!

Good luck!

Ford Focus 2 battery

Every second motorist has encountered the problem of a dead battery. The reasons for sudden wear and tear are different: poor workmanship, violation of operating conditions, defects, exhaustion of its resource.

The decision to restore the battery (reanimation) is made by the service station master, who conducts a comprehensive diagnosis of the technical equipment.

What kind of battery is on Ford Focus 2

Despite numerous extensions of service life, there comes a time when recharging requires replacing the battery with a new one. And here the owner has a problem: brand, capacity, price.

Some drivers don’t bother and purchase a similar copy of the battery. Sometimes it happens that the previous version of the battery is no longer produced, and you have to look for solutions again.

Parameters to consider when purchasing a battery:

• Size: length x height x width. Exceeding factory standards will result in the battery not fitting into the stock compartment;
• Terminal connection diagram: left / right plus;
• Nominal battery capacity;
• Current strength.

For the power supply of a Ford Focus 2 car, the battery parameters are as follows:

• Right polarity of the positive terminal;
• Capacity 65 – 75 Ah;
• Current 675 A;
• Terminal type: standard.

Dimensions of the factory battery for Ford Focus 2: length 278 mm x width 175 mm x height 175 mm.

Note to the driver. Only in the second generation Ford Focus the height of the battery case is 175 mm, in all other modifications, including restyling, it is 190 mm.

At the same time, a number of car owners willingly boast that they can install a battery from their “big brothers” on the second generation Ford Focus. In this case, it is necessary to bend the metal pressure plate. How expedient this is - each owner decides for himself.

Characteristic signs of a faulty Ford Focus 2 battery

• Cloudy consistency of the electrolyte in the jar(s). In its natural form, the electrolyte is colorless;
• Lead falls off the plates;
• When charging, one can boils or does not boil at all;
• Abundant boiling of all cans. Most likely, strong sulfation, you need a diagnostic device - a multimeter;
• During the charging process of the battery, the current does not decrease, but increases. Most likely there is a current leak between the lead plates, the electrolyte is of poor quality;
• When the plug is loaded with a current of 100A, the voltage drops to 10 Volts;
• When loaded with a 100A plug, the electrolyte boils in several jars;
• Check the condition by activating the low beam for 4 - 5 minutes. In good condition, the voltage shows at least 12.2 V. If the reading is below 12.0 V, the battery must be recycled;
• Checking the time until complete discharge using a 100 Watt light bulb;
• Checking the battery for self-discharge: charge it to the maximum, and then carry out a control measurement. If the indicator is above 0.4 V, the power source needs to be changed;
• The battery becomes excessively hot during charging;
• There is a crack, dent, or other defects in the plastic case, which led to electrolyte leakage;
• Near the battery you can smell rot and hydrogen sulfide;
• Electrolyte leakage from under the plug (cap);
• The voltage on the current leads is below 9.0 V;
• A light came on on the dashboard - an indicator indicating a lack of battery charge.

What to do if the battery on a Ford Focus 2 is dead

If you forgot to turn off the radio or headlights at night, restoring the battery charge will not be difficult. Even on the way, you can ask for a light with crocodiles.

Another thing is when the battery fails due to its “service life”, resuscitation is a controversial matter.

The main task is to clean lead plates from oxidative deposits. Scale is formed during the systematic charging and discharging of the battery. Each time the thickness of the layer increases and increases. Eventually, the charge stops flowing to the lead plates.

We carry out cleaning using a special liquid; before doing this, it is necessary to remove the power source from its regular place. We buy a new electrolyte, check its density, it should be no lower than 1.28 g/cc. We dilute the additive in it and pour the resulting mixture into the battery.

We tighten the plugs, connect the terminals, set the current strength to 10 times higher than the nominal value, and start the charge. After several hours of charging, we completely discharge the battery. We repeat the cycle 3 – 5 times.

We measure the voltage at the terminals again, it should not be lower than 13.8 V. If necessary, increase the density of the electrolyte to 1.28 g/cc, add distilled water.

Battery resuscitation at home is complete.

Guide on how to remove the battery from Ford models

Ford Kuga car

The design features of Fords prevent independent intervention in the operation of technical components and electronics. What should I do if the battery needs to be replaced? Many Ford engineers in its homeland consider it natural to contact a car service center and, if necessary, call a tow truck.

The traditions of driving and servicing cars in Russia have taught car enthusiasts to overcome all obstacles and change the battery with their own hands. Once you figure out how to do this, there are no questions later.

Depending on the car model, the battery is available to varying degrees. If you have little experience in dismantling, before unwinding and disconnecting, take a close-up photo so that you can accurately restore the connections later.

Focus

Ford Focus car design

For a comfortable view and, if necessary, to remove the battery from a Ford Focus 2, 3, restyling strictly in a position without tilt (for example, a cracked housing), it will be convenient to remove the air filter.

Find out the charging time of your battery

Let's figure out how to remove the battery from Ford Focus 2, 3, restyling, without removing the filter:

• turn off all power consumers;
• remove the cover from the battery;
• remove the “+” terminal;
• unscrew the clamping bar;
• release and bend the wall of the battery compartment from the “+” terminal side;
• make sure that the battery is able to move around the compartment;
• lift the part that is closer to you, as in the photo;
• at an angle of 45°, remove the battery enough to gain access to the “-” terminal;
• disconnect the negative terminal;
• take out the battery.

The second generation of Kuga was released in 2013, despite noticeable changes in the body, the location of the battery in the Ford Kuga 2 has remained recessed since 2013; access to it is gained by removing the air filter, or by dismantling the shelf under the front window, which is also called a frill.

In car repair shops, it is customary to remove batteries on Ford Kugas after first disassembling the air filter.

For an experienced electrician, dismantling it is not difficult; the method has important advantages over gaining access through the top:

• the freed up space is definitely enough to get the battery out;
• After assembly, no wiper adjustment is required.

Remove the filter and take out the battery:

Removing the battery from the car

• remove the bolts from the filter cover;
• remove the cover;
• remove and set aside the air filter;
• unscrew the bolts from the filter housing and remove it;
• remove the battery cover;
• move the wires attached to the wall of the battery compartment forward towards the headlights;
• unfasten the wall that borders between the filter and the battery, bend it;
• remove the nuts and fixing bar;
• remove the terminals;
• remove the battery.

Access through the top requires a minimum of mechanical work; with little or no experience, removing the frill from a Ford looks easier. There is a possibility of a problem with the battery size. It does not always pass through the resulting opening. Often, after removing the frill, you have to disassemble the filter.

Replacing the battery on a Kuga through a removed frill:

• remove the wipers by unscrewing the nuts with a 15th wrench;
• tighten the bolts that hold the shelf;
• disconnect the brake fluid reservoir from the shelf;
• remove the spring fastenings of the shelf;
• remove the shelf along with the decorative trim;
• remove the cover from the battery;
• disconnect the terminals;
• remove the nuts and clamping bar holding the battery;
• remove the battery, if necessary, bending the wall of the battery compartment.

For clarity, watch the video.

Mondeo

Ford produces the 5th generation of Mondeo cars. All trim levels, including the large Mondeo 4, have a deep-seated battery.

It is obtained after dismantling the air filter:

Ford Mondeo car

• open the engine cover;
• remove the sensor wire;
• remove the pipe from the air filter;
• remove the filter and its housing;
• disconnect the front wall of the battery box;
• disconnect the negative from the ground, wrap it with electrical tape;
• remove the positive terminal;
• remove the battery clamp from the front side;
• slide the battery towards you;
• disconnect the negative terminal;
• take out the battery.

Transit

The design of the Ford Transit is designed for frequent self-charging of batteries, so getting them is quite simple:

Ford Transit car

• remove or move the driver's seat (depending on the Transit model);
• remove the cover from the battery;
• Having access to the batteries, disconnect the terminals;
• unscrew the fixing bolts and the bar;
• take out the battery.

On Ford Transit cars until 2000, the plant provided space for one battery. Afterwards, cars with space for two batteries began to be produced. You can use one or two batteries as needed, depending on the driving cycle.

When replacing an old battery with a new one, be sure to ensure that the polarity is reversed before installation!

How to select and, if necessary, replace the battery in a Ford Focus 2?

To ensure the normal operation of electronic devices and devices in the car, a powerful battery must be used. We are talking about cars from any manufacturer, including American-made cars, which are characterized by the presence of many voltage consumers. In this article we will talk about how to choose the right battery for a Ford Focus 2 car and how to replace it.

Criterias of choice

The choice of battery for the first, second or third Focus should be in accordance with the manufacturer's recommendations. According to experts, today when purchasing, you should pay attention to a dry-charged battery. One of the key advantages of such devices is their long shelf life and, accordingly, service life.

In addition, dry-charged batteries are characterized by the following advantages:

1. Possibility to check the battery for Ford Focus 1, 2 and 3 right at the time of purchase.
2. Typically, before being offered for sale, the battery is tested and fully charged to the level required for normal use.
3. Dry-charged devices are characterized by the presence of a large volume of various additives in the electrolyte composition, which helps to increase the service life.

Ford Focus engine compartment - battery is covered with a lid
It is impossible to say exactly which battery is best to buy for Ford Focus 2, since products from different manufacturers have both advantages and disadvantages. To choose the most optimal option, you should be based on your experience, as well as recommendations from Focus owners. Today, the most popular batteries among domestic buyers are Warta, Bosch, Viking, etc. batteries. Such models have long established themselves as reliable batteries that rarely fail. Of course, you can choose other manufacturers, but the most important thing in this case is that the device fits Focus 1 or 2 sizes.

So, to select the correct battery, you should take into account the recommendations of the automobile concern, as well as the technical characteristics of the vehicle. For example, if the capacity size must correspond to 70 Ah, it is not recommended to buy a battery with a different capacity. Of course, sometimes you can deviate from this rule and purchase a battery with a smaller capacity, but this is true for Focus 1, 2 and 3 cars, which use more viscous oil. In addition, a lower capacity is relevant for vehicles that have problems with the ignition or power systems.

Same engine compartment - battery cover removed

It is worth considering that in some cases it is necessary to install batteries with a larger capacity. In particular, we are talking about cars equipped with various electronics - GPS devices, video recorders, powerful sound systems, monitors, etc. When driving on the highway, a conventional battery can cope with powering such devices, however, when driving around the city and in traffic jams, the car owner may encounter certain problems. So when purchasing a device, you must first of all be guided by the features of your vehicle.

So, what features need to be considered when purchasing a battery:

1. First of all, you should pay attention to the battery parameters, in particular the capacity size, voltage and current parameters. To understand what characteristics a battery should have, you need to familiarize yourself with the requirements of the car manufacturer, which should be described in the service manual. In general, these recommendations will be fundamental when choosing.
2. You will also need to check the type of terminals and their location, as this parameter may vary for different cars. In practice, the size of the terminals is usually the same, but the location may vary.
3. When purchasing a device, you need to pay attention to the reserve capacity parameter. This characteristic must be at the required level, since it is the capacity that determines the number of hours of operation of various devices and instruments when the generator is turned off.
4. An equally important parameter is the selection of the voltage level for low temperatures - this parameter must also comply with the recommendations of the car manufacturer. It should be noted that this value depends on how the power unit will start at subzero temperatures. It is best for this indicator to be as high as possible.
5. Battery size. If you are faced with the need to replace a device for the first time, you should take into account that high-capacity batteries may have increased dimensions compared to standard ones.

Instructions for dismantling and replacing the battery

In general, replacing a battery is a fairly simple task that any car enthusiast can handle. To perform this procedure, you only need to prepare in advance the wrench needed to remove the terminals. It should be borne in mind that the battery itself is a rather heavy device, which will require some effort to dismantle.

Algorithm of actions

To remove the battery on a Ford Focus, follow the steps:

1. First you need to turn off the ignition and all devices powered by the battery. Dismantling the battery wires is carried out one by one - first you need to disconnect the ground. If you own a 1.8-liter or 2-liter turbodiesel car, you will need to remove the air filter to remove the device.
2. Next, you need to remove the battery cover, which is mounted on all second Focuses. Then you should unscrew the screws that secure the negative wire to ground. To do this, slightly loosen the nut on the wiring, and the bar itself, used for the clamp, needs to be lifted, while unscrewing the nut.
3. After these steps, you need to remove the negative and positive wires from the terminals. To do this, unscrew the nuts and then open the wiring retaining elements and move them aside. When removing the wires, it is necessary to prevent them from shorting with the body or tool.
4. Then simply unscrew the nut that secures the device fixation bar and remove it. The battery must be held as firmly as possible to prevent it from falling.

Sorry, there are no surveys available at this time.

Brands

Bosch and Varta have become popular batteries for Ford Focus 2 1.6 restyling (100 hp).

Which battery to install on Ford Focus 2 1.8? Varta, Bosch, Moll, Tudor have quality comparable to prices. Moll is the most expensive option. It has a well-thought-out design of increased strength.

There are practically no complaints about Tudor batteries when working in severe frosts. Bosch and Varta are 2 brands of the same manufacturer, the most common among car enthusiasts due to their relatively reasonable price and sufficient reliability for 3-5 years.

The original with the Ford logo is not popular among car owners. The price-quality ratio is noticeably inferior to those listed above.

Step-by-step replacement instructions

To remove and replace the 3rd generation Ford Focus battery, you only need a wrench with a 10 mm socket and an extension. For the 2nd generation Ford Focus, you will also need a screwdriver to press out the latches of the plastic cover (they are more rigid and difficult to pull off with your fingers). Another nuance: in a car with a 1.6-liter gasoline engine, you do not need to remove the air filter. For diesel and petrol 2.0 liters – mandatory. Therefore, before removing the battery for replacement from a Ford Focus 3, you should check the type of installed engine in the technical documentation. If its power is 150 horsepower, then the filter must be removed, since without this it will not be possible to get to the battery. For internal combustion engines of 105 and 125 horsepower, this is not necessary. Otherwise, replacing the battery is carried out similarly according to the following algorithm:

All that remains is to replace the battery with a new one. Assembly is carried out in reverse order. In the 2nd generation Focus, where restyling has not yet been carried out, although the filter does not need to be completely removed, without an extension cord it will not be possible to unscrew the battery lock. And if a non-original battery is installed, that is, with smaller dimensions, then the latch moves in the compartment (there are moving grooves for it).

After installing a new battery, you will also need to reset the control unit. To do this you need:

Once the reset is complete, the battery icon on the panel will light up - this confirms that the procedure was successful. In this way, intelligent charging is “reset” and configured to work with a new battery.

So, it is recommended to change the battery in a Ford Focus after about 3-4 years of active use. The whole procedure takes 15–20 minutes. It is not necessary to charge a new battery before installation if its charge is sufficient for at least the first start of the engine. And most importantly, do not forget to reset the BMS settings, since without this the control unit may not work correctly (for example, lower engine speed at idle).

We service the battery. Removal/installation.

Imagine that your Focus, purchased not so long ago, maybe a little more than six months ago (color, body, engine size and equipment do not matter), one fine day refused to start. Instead of the usual sound of the starter turning, did you hear a click-click-click-click-click-click?

Congratulations - you also got it! (You can find and discuss the reasons for battery discharge in this topic All about the battery) Of course you are right, what normal person would try to measure the density of the electrolyte in a NEW car. (I thought so myself too. Now I’ll do this on a new car too

)

But emotions aside, let's get to the point: the battery is discharged - that's a fact. But don’t rush to “just charge” it. As you know, Focuses are equipped with calcium batteries. This is the whole problem. Be sure to check the density of the electrolyte. Pay attention here. My density was 1.15 - this is below all permissible limits. Therefore: 1. If you do the same, then point 2 is NOT FOR YOU. 2. If your readings are about 1.20 or higher, then first try to charge it, but not like a regular battery, but with a low current of 1-2 Amps for 2-5 days. (Be sure to make sure there is no strong boiling). If it doesn't help, read on.

So you have 1.15 or so. Alas, nothing can be done here. And no amount of charging will bring the battery back to life without damaging your health and resource. There is only one way out - replacing the electrolyte (although this concept is not practiced by specialists). It was not for nothing that I mentioned at the beginning of the topic that your car should be up to six months or a little more. Then this procedure should be as painless as mine. Just during the replacement process, the battery will have to be turned over. On aged and old batteries, this is fraught with short circuits due to sediment at the bottom of the battery.

So further in order: 1. Go to the Auto Parts store and buy 3 liters of electrolyte. The capacity of this battery is about 2 liters. But you need a reserve, you never know if you spill it past, and then the electrolyte is sold mostly in 1.5 liter bottles. Therefore, 3 liters is just right! (Just under no circumstances tell you why you need it. They may dissuade you. Remember: YOU HAVE NOTHING TO LOSE. If you charge, then if you are lucky and reach the coveted 1.27, then the process of such a long charging will reduce the battery life by at least half.) 2. Take your battery out of the house and remove the plugs. 3. Pour out the unusable electrolyte. (It is better, of course, to dig a small hole). Just don't pour it down the drain. This is still rubbish. In this case, we choose the lesser of two evils. 4. Fill in new electrolyte. The most important thing here is to minimize the time between draining the old one and filling in the new one. The plates do not like open air. Close the traffic jams. 5. Carry the battery home. Open the plugs and charge it with a low current of 2 Amperes. The density of store-bought electrolyte is 1.27-1.28. After pouring into the battery, it should fall a little, mixing with the remnants of the old one. 6. Use a tester and a hydrometer to control the process. When the voltage on the battery is 15.7V (I couldn’t do it anymore after 6 hours of charging), and the density is 1.26-1.27, you can consider that the battery is charged and turn off the charger. After the battery cools, the density will rise a little more. 7. Install the battery on the car and enjoy the usual cheerful sound of the starter.

Device programming

The key fob does not always start working after replacing the power source. First of all, you need to check whether the battery in the car is dead. To do this, you can directly try to start the car or turn on the headlights. If the battery is in working condition, then the key needs to be reprogrammed, since the car does not “see” it.

To do this, insert it into the ignition switch and turn it to the 2 o'clock position four times in a row. Then return it to 0 and wait for the sound signal. This will take about ten seconds. A sound will be heard, which means programming has begun. Now quickly press the button on the key. The lock should click, which means the key has received a new program.
