Which battery for VAZ 2107 carburetor is better

On the VAZ-2107, the on-board electrical network is powered by two sources - the battery and the generator. The first provides power until the engine is started, the second - after starting. But if a generator is a mechanical device that, with proper care, can work for decades, then the battery wears out over time to such an extent that it can no longer perform its functions.

The main purpose of the battery is to supply electricity to the electric motor (starter) so that it can spin the crankshaft and elements of the ignition system so that the engine starts, after which the generator takes over the role of the power source.

In addition to the starter and ignition system, the battery supplies power until the engine starts and the rest of the car is consumed, and also provides recharge when the load on the on-board network is large and the generator cannot cope.

Battery features

If we look at a battery in a simple way, it is a storage facility for electricity, which it releases when needed and then replenishes it from the generator. All its work is based on chemical processes that gradually destroy it. After a certain period of operation, the degree of damage to the internal elements of the battery reaches such a level that it is no longer able to retain and deliver the charge required to start the engine.

The service life of rechargeable batteries depends on many factors. Under some conditions, a good VAZ-2107 battery can last 7-8 years, but under others it won’t last even 5 years. But in any case, if the battery is not able to hold a sufficient amount of energy and quickly discharges, then it needs to be replaced, since these elements cannot be restored.

So, the battery has already exhausted its resource and it’s time to go get a new one. At the same time, it is important to choose the right battery for the VAZ-2107 car, because not every battery is suitable for installation on this car.

According to GOST, the VAZ-2107 must be equipped with a battery marked 6ST-55 (6 - number of cans, ST - starter, 55 - capacity in Ah). In Soviet times, this was quite enough to make a choice. Now the battery market is very extensive, and the indicated marking is no longer used, although the capacity indicator is still needed.

When determining which battery is best for the VAZ-2107, we will not consider existing types, but will focus on the most common ones - acid ones, which perform their functions perfectly on this car.

Which battery to buy for VAZ 2107

A car battery that has expired requires replacement, and the owner is faced with the question of which battery to buy for the VAZ 2107.

Today, solving this dilemma is not easy, since there are a huge number of them on sale from a variety of manufacturers.

A car battery is essentially one of the most critical elements of a car, since if it fails, starting and operating the car becomes very problematic. Therefore, when purchasing a battery, you need to approach it carefully, having first considered all its strengths and weaknesses.

A car battery performs several functions:

Starts the engine
Provides power to the vehicle's electrical equipment when the engine is not running: parking and side lights, interior lighting, car radio, alarm and other consumers
If the generator fails, it ensures further movement, provided it is charged

To carry out all of the above functions, a car battery must have certain properties that meet the specified parameters of a particular car model.

Types

As for the type of battery, according to this parameter, batteries can be divided into:

Serviced;
Maintenance free;

Serviceable batteries are equipped with special plugs on the top cover.

In such a battery, it is possible to open each of the cans, check the electrolyte level and, if necessary, replenish it and bring the density to the required level. On the one hand, this is a positive quality, since periodic maintenance allows you to extend the service life. But on the other hand, such a battery is another element that requires attention.

In maintenance-free batteries, the case is sealed and they do not require any intervention from the driver, the only thing is that you will have to periodically recharge it.

what is the polarity of the battery?


	One of the most optimal batteries for the VAZ 2107 car, with a capacity of 60 Ah.

The higher the battery capacity, the greater its power. In addition, in modern models a lot of additional equipment is installed as options, which immediately increases the load on the battery, which also must be taken into account when purchasing it.

In general, capacity is characterized by the amount of electricity that the battery is capable of delivering in long-term discharge mode. Typically, the capacity is determined at a 20-hour discharge. When determining the nominal capacity, the battery is discharged continuously (at +25°C) for 20 hours with a current equal to 0.05% of the total battery capacity. Let's say, for a 60Ah battery the discharge current will be 3A, and for a 90Ah battery – 4.5A.

There is also such a thing as reserve capacity, which is measured in minutes and should approximately correspond to the driving time of the car in the event of a generator failure. For example, for a 55Ah battery, the reserve capacity will be approximately 85-90 minutes. What does it mean that the car moves thanks to the energy of the battery (fully charged at the time of generator failure) for 1.5 hours.

Capacity

Capacity is one of the most basic parameters of any battery (measured in Amp-hours). If we look at this term in a simple way, it indicates how much energy the battery holds. This parameter is determined using a long-term discharge (20 hours) under strictly established temperature conditions (+25 degrees C).

According to GOST, a battery with a capacity of 55 Ah is installed for the VAZ-2107, but this is more of a recommendation than a strict requirement. A battery with both 50 Ah and 60 Ah will work well on this car. But here it should be understood that the higher the capacitance value, the more energy it will contain. Taking into account the fact that additional consumers are now installed on cars (audio system, all kinds of auxiliary equipment), additional Amp-hours will not be superfluous.

One more nuance regarding capacity. The VAZ-2107 was produced with power plants that used different power systems - carburetor and injector. So, for the carburetor version you need a battery with a larger capacity than for the injection version. This is explained simply - the injector makes it easier to start the engine under different conditions, which means the starter consumes less energy. Therefore, in the case of an injection power system, a battery with a capacity of 50-55 Ah will be quite sufficient; for the carburetor version it is better to install a 60 Ah battery.

Battery for VAZ 2107

On the VAZ 2107, the on-board power supply comes from the battery and generator. The battery is the source of energy when the engine is turned off, and the generator starts working after starting the power unit. The battery loses its function over time, causing it to be unable to crank the starter and start the engine. In addition to the fact that the battery requires replacement, you need to know with what parameters and how to install the battery on your “seven”.

What is it used for?

The main purpose of the battery is to power the starter to crank the engine and supply voltage to the ignition system to start the engine. Until the engine starts, the battery provides power to all consumers of the car (lighting, heater, car radio, etc.). In addition, if during engine operation a large load is placed on the on-board network and the generator is not able to produce the required current, replenishment is also carried out from the battery.

Starting current

Starting current is a battery power parameter. It indicates the maximum current value the battery can deliver in a short period of time. Essentially, this is an indicator of the battery’s ability to start the engine under unfavorable conditions (in this case, low temperature).

When selecting a battery according to this criterion, you should take into account the region in which the car is operated. So, for the southern regions, you can especially consider the values of the starting current (a battery with average values is also quite suitable). But for northern regions, the higher the starting current value, the better, since the likelihood that the battery will be able to start the engine in severe frosts is greater.

VAZ 2107 battery charging diagram

One of the main electrical circuits of a car is the battery charging circuit. As the owner of a VAZ 2107, you need to have at least a minimal understanding of the principle of charging the power source, what elements are involved in this circuit, which will allow you to take appropriate actions in the event of problems.

The above diagram makes it clear that a malfunction in the battery charging circuit is possible anywhere. This could be, for example, problems with the brushes of the relay regulator or oxidized contact on any part of the electrical circuit. As a result, the generator will not be able to provide a full charge to the battery, which will lead to its gradual discharge.

When choosing a battery for a VAZ 2107, you must adhere to the recommended parameters. This will ensure trouble-free installation and operation of the product for a long time. If you have problems charging the battery, after reading the diagram, you can independently find and fix the problem.

It is not difficult to purchase a VAZ 2107 battery; the batteries for this vehicle are standard and are available for sale in any car store. But it should be noted that it is important to carry out the purchasing process after preliminary preparation. There are a number of nuances related to the location of the terminals and the type of equipment itself.

If the charging light on the instrument panel periodically lights up while driving, then you need to carefully examine the installed battery. This unit fails once every 5 years. Moreover, the service life can vary significantly - depending on a variety of factors. The frequency of use of the vehicle, operating conditions and many other factors affect it.

When choosing a battery, it is important to pay attention to the following basic parameters:

capacity;
starting current value;
polarity – location of the positive and negative terminals;
dimensions of the battery itself.

It should be noted that not all batteries will fit into the vehicle in question. That's why it's better to look under the hood first. Only after this do you go to a car store to purchase it.

Polarity

The polarity of the VAZ-2107 battery characterizes the position of the battery terminals for connection to the on-board network. Currently, batteries are produced in two types according to polarity - direct and reverse. This parameter seems to be minor, but if it is not taken into account, problems with connecting to the network may arise.

The polarity is determined very simply - turn the battery towards you “facing” (the terminals should be located closer to you) and look where the “positive” terminal is located. If it is on the left, the polarity is straight, on the right, it is reversed.

Since direct polarity was used in the Soviet Union (it is also additionally called “Russian”), it can be understood that this is what is used on the VAZ-2107. That is, when choosing a battery for this car, you need a battery whose “plus” is located on the left (but it is important to correctly place the battery in front of you when determining the polarity).

Options

In order to choose the right battery for a VAZ car, including UAZ, you need to know what functions it performs. The main purpose of this device is to start the engine. The second function is to provide power to consumers of the vehicle's electrical network in the event of a generator malfunction or when the engine is not running.

Engine compartment of the seven

The device must be selected in accordance with the needs of the machine's electrical network. The main parameter you need to focus on is capacity. It must correspond to the number of electrical appliances and the engine size of the VAZ 2107.

The second important point to pay attention to is the location of the output terminals. Polarity can be direct or reverse. For batteries with reverse polarity, the plus is on the right, and with direct polarity, it is on the left.

Forward and reverse polarity

The next important parameter is the starting current. The value of this current determines how long the battery can turn the starter, which is especially important when starting the engine at low temperatures in winter.

In addition to the listed parameters, the dimensions of the device are important. In order for the new battery to fit into its regular place without any problems, you need to measure the height, width and length of the old one.

Dimensions

Let's move on to the overall parameters, since they also need to be taken into account. In the engine compartment there is a special area with fasteners for installing the battery. If you choose the wrong battery size, it may simply not fit on this site, which is why the reliability of its fastening will be in question. The required dimensions of the VAZ-2107 battery are as follows: length - 242 mm, width - 175 mm, height - 190 mm. Let us immediately note that most batteries with a capacity of up to 60 Ah have exactly these dimensions.

So, we have determined that for the VAZ-2107, a battery with a capacity of 50-60 Ah, with direct polarity, will be optimal. As for starting currents, we focus on the weather conditions of the region in which the car is used.

As for price categories, it all depends on how much you can spend on the battery. If finances allow, then it is better to take batteries from well-known manufacturers (BOSH, Mutlu, etc.), although they are more expensive. But there will be confidence that the battery characteristics correspond to the declared ones. You can, of course, buy a battery from a little-known manufacturer, but no one will guarantee the quality and compliance of the characteristics.

To carry out all of the above functions, a car battery must have certain properties that meet the specified parameters of a particular car model.

Battery selection

When selecting a battery for 2107, you need to take into account the polarity. On this model, the positive terminal is on the right, so only batteries with straight polarity are suitable. Also consider the size of the area under the battery. Now batteries can come in different sizes, so be sure to check this factor. Otherwise, the battery will jump, which will negatively affect its performance.

Consider the features of the generator you have installed. It should deliver a current at least not much lower than the battery capacity. In practice, a 45 or 55 Ah battery is suitable for a 40 A generator. Such a generator will not be able to charge even a battery with a capacity of 60 Ah. And you will regularly face the need to additionally recharge it. Such operation will lead to rapid battery failure. Before purchasing a battery, you should definitely check the generator performance. They can be read on its end. If you can’t make out the inscription, you can determine the “genes” model by eye and look at the indicators in reference books.

Pay attention to the starting capacity. For the VAZ 2107, it is recommended to use a battery with a rating of 50-55 Ah, this ensures trouble-free cranking with the starter 20-25 times. Some drivers install larger batteries, but for them to work properly, it is advisable to install an appropriate (more powerful) generator at the same time (see the article “Which generator is better to install on a VAZ 2106 and 2107”).

Starting current, this indicator shows how long the battery can supply maximum current to the starter. The reliability of the battery in winter largely depends on this indicator. It is advisable to select a battery with the highest possible starting current. But keep in mind that this can negatively affect the condition of the starter brushes, accelerating their wear. This indicator is checked at a temperature of – 18°C.

Determining the polarity of the battery

The next indicator is polarity. Polarity can be direct or reverse.

This is reflected on the battery by the location of the terminals: Left (L) + left plus, Right (R) + right plus. The starting current usually depends on the battery capacity. Often, these two indicators are proportional: the larger the capacitance, the greater the inrush current, although there are exceptions. Next we decide on the sizes. It is best to take approximate measurements yourself, then the picture of battery selection will be clearer, since based on approximate parameters we will be able to select a standard type for you. Selecting a battery for a VAZ 2107 is not such a difficult task.

I can outline some standard parameters that are suitable for this type of machine.
