The battery determines how quickly the car will start and how electrical appliances will operate when the engine is not running. Therefore, it is important to choose the right device. The article discusses the battery for the VAZ 2107 car: what parameters should be taken into account when choosing, what are the main faults.

Selection options

In order to choose a VAZ-2107 battery among the many offers, you should take into account several factors, namely:

• Type;
• Capacity;
• Starting current;
• Polarity;
• Dimensional parameters;
• Price category;

If you take all of the above into account, choosing a battery and installing it on a car to replace a worn one will not be difficult.

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.

All consumers of electricity in any vehicle receive it from two suppliers - the main and backup. Most of the time, the generator operates as a source, and we need the battery when we need to start the engine and during sudden surges in electricity consumption. The “life” of a battery cannot be called easy, both in heat and cold (especially in frost) it must regularly produce a large current. Constant “stress” breaks it down and we start thinking about buying a new battery. So how can you choose a battery for the VAZ-2107 without overpaying for unnecessary bells and whistles? Let's try to figure it out.

How does a battery work?

The battery can ensure the fulfillment of the main task - to power the starter and all consumers of electricity of the VAZ-2107 car, using chemical reactions. This method has been known for more than a hundred years. When charging from an external source or generator, chemical transformations of lead and sulfuric acid take place inside the battery, and when discharging, the process proceeds in the opposite direction. Over and over again, these processes are repeated, gradually wearing out the filler (active mass) and chipping it. Because of this, our battery stores less and less energy and, one “bad” day, we cannot start the engine. The life of a battery is shortened by deep discharges, short circuits, freezing of the electrolyte (this is when a discharged battery is left outside in the cold), overcharging when the relay regulator is “broken” and other reasons. How to prepare your battery for winter can be found here . A high-quality battery, with careful use, can last up to 7 years on a VAZ-2107. But, on average, they last from 3 to 5 years.

The plant recommends installing this battery on the VAZ-2107 - 6ST55. This brand means that the battery is needed as a starter (produces a high current during short starts), consists of six compartments (cans), the electrical capacity is 55 ampere-hours. Now, from this marking, only the electrical capacity is relevant when purchasing, the rest of the information is outdated.

Selecting the battery type

In stores you can find serviced and maintenance-free batteries.

If there are traffic jams, the battery requires a little more of your attention. You will have to monitor the electrolyte level and check the density. Please note the following - the plugs are hidden under stickers, which does not make the battery maintenance-free.

There are no plugs, access to the electrolyte is closed - this is a maintenance-free battery. The entire period of its operation is provided by internal resources. You only need to monitor the voltage in the on-board network. These batteries are significantly more expensive.

Don't forget about polarity

Batteries are produced with direct or reverse polarity. If you buy the “wrong” one, it won’t fit, the wires won’t be long enough. For our VAZ-2107 we need a battery with direct polarity, this is when the right is “minus” and the left is “plus”, when viewed from the side on which the terminals are installed. This polarity has its roots in the USSR and is used on most domestic cars.

What battery capacity is suitable for the VAZ-2107

This number in the marking is of great importance. The minimum required capacity for our harsh climate is 55 ampere-hours. The battery compartment can accommodate a maximum battery capacity of no more than 62 amp-hours. The higher this number, the longer in winter you can “turn” the engine, which means the greater the chance of a successful start. For injection engines, starting conditions are facilitated by a special starting program, so you can install a battery with a smaller capacity.

What does inrush current affect?

This parameter affects the power that the starter consumes when starting the engine. And everything depends on the internal “structure” of the battery - the thicker the conductive plates, the purer the electrolyte and the better the active mass, the higher the starting current will be. In cold weather, a high starting current is good, the starter spins faster, and the engine starts more confidently. The starting current of batteries can be from approximately 300 to 1000 amperes. The battery in the photo delivers 530 amperes at startup, which is quite enough for central Russia.

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.

Types of car batteries?

Design of a lead-acid battery The most common type of battery is lead-acid. In such batteries, the usual electrolyte is a mixture of distilled water and sulfuric acid.

AGM battery design
Another type of battery is based on AGM (Absorbent Glass Mat) technology. In them, the electrolyte is absorbed in glass fiber.

Battery features for different “Seven” models

VAZ 2107 is a sedan with four doors. It began to be produced in 1982 on the basis of the Lada 2105 at the AvtoVAZ plant. The main components and internal structure of the VAZ 2107 have not changed. The “Seven” differs from the VAZ 2105 in its interior trim, plastic bumpers, chrome-plated radiator grille, installation of an oil pressure indicator, tachometer, changing the speedometer to 180 km/h, and the shape of the hood. In 2001, a new model VAZ 2107 - 21074 appeared with a 1.7 liter engine producing 77 hp. With.

The battery capacity depends on the type and size of the engine. Since 1982, the “Seven” has been updated with new types of engines.

Engine volume, cubic meters cm

Manual Transmission

The Semerka car is equipped with a 6ST-55 battery in accordance with the state standard. It is located near the engine, in front of the car on the right. The energy storage device has the following features:

• rated voltage of the energy storage device, 12 V;
• nominal capacity, when the discharge mode lasts 20 hours and the electrolyte temperature is +25 ⁰C at the beginning of the discharge, 55Ah;
• charge current, 5.5A.

The energy storage device consists of 6 batteries with a voltage of 2 V, which are connected in series. The batteries are placed in isolated parts of the energy storage device filled with electrolyte. The energy storage compartments are equipped with holes and are closed with lids. At the edges of the case there are positive and negative terminals to connect the electrical wiring of the “seven”.

Which good battery to choose for VAZ: top 10 rating

The following is a list of the most profitable solutions for installation on domestic cars.

10th place: BOSCH S4 005 Silver

– View in Yandex.Market Price from 5000 rub.

Oddly enough, the Bosch model occupies the last place in the top. The mid-budget modification has sufficient starting current and a capacity of 540A and 60 Ah, respectively. However, the good “on paper” characteristics in practical use are significantly inferior to analogues. The reserve capacity of the unit is inferior to its substitutes and is actually at the level of batteries in the lower price range. The next negative factor is complete uselessness in severe frosts. In the warm climate of the southern regions, starting problems do not arise. However, at -20-25 degrees Celsius, after the first cranking of the starter, a drop in power occurs, which is perceived extremely negatively by domestic cars. The inability to cope with deep discharge modes also stands out. Resuscitating the capacity is extremely problematic. The result is low demand among buyers. Advantages:

• capacity and starting current;
• availability of factory warranty.

• drop in power after the first cycle of starting the internal combustion engine;
• intolerance to severe frosts.

9th place: ExideExcell EB602

– View in Yandex.Market Price from 4300 rub.

The answer to the question of which battery is best for the VAZ 2107 and other classics will be 9th place in the rating. The presented model stands out among competitors' offerings with average characteristics in all areas. There is a good capacity here - 62 Ah, which is good for older cars where there are problems with the wiring or a lot of additional electrical equipment is installed. A starting current of 540A is also quite sufficient. Good build quality and thoughtful design have a positive effect on operation. A supposedly maintenance-free battery can be “restored” thanks to the presence of hidden caps for refilling electrolyte. The same jars are located under the decorative lids. The next factor is excellent frost resistance. The cheap battery functions properly in temperatures down to -35, which is a good result even for the leaders on the list. There is also a low susceptibility to self-discharge, which has a positive effect on long vehicle downtimes in winter. The likelihood of finding a car with a “dead” battery in the garage is minimal. The low ranking of the top is due to a drop in charging speed and reserve capacity in the cold. Advantages:

• quality at a reasonable cost;
• starting current indicators;
• resistance to freezing;
• lifetime.

• performance drops with decreasing temperature.

8th place: ToplaEnergy 60

– View in Yandex.Market Price from 4800 rub.

A time-tested modification of the ToplaSlavenskoye company. After analyzing customer reviews, we can establish that the strength of the battery is a good resource and a good starting current of 600 A. The actual capacity is 60 Ah, which is also not bad. Optimistically considering the option when asked which battery is best for a VAZ car, you can safely choose this model. Small-volume gasoline fours go well with the unit. Starting currents easily turn the car starter in winter. Also, long periods of downtime are not a problem - the susceptibility to self-discharge is minimal. However, when installed on diesel engines and impressive power plants, pitfalls are revealed. For example, there is concern about the charge being released too quickly during a cold start. If you cannot start the engine the first 2-3 times, then starting the internal combustion engine will be problematic. The low position of the top is due precisely to the rate of fire of the model. In some regions of Russia this may become a critical factor. Advantages:

• decent quality;
• starting current;
• The capacity reserve is suitable for tuned models;
• resistance to shaking.

• charge release and, as a consequence, a limited number of attempts to start the internal combustion engine in winter.

Battery device

The battery is an integral part of any car and the main source of current along with the generator. It starts the engine, maintains power when it is turned off, and assists the generator in powering applications such as heated seats or power windows.

When the engine is running, the battery is charged by the generator, and comes into action when the electrical load begins to exceed the power that the generator can create.

The VAZ 2107 uses lead-acid batteries. They all have a voltage of 12 volts, but different charge capacities: from 40 A/h to 65 A/h.

As the diagram below shows, the battery consists of 6 small “cans” located in special compartments of its ebonite case. Their walls are made of lead plates of different poles. Each mini-battery is filled with electrolyte, which contains charged particles.

In principle, the operation of a battery is nothing complicated: the movement of particles and, accordingly, the work of current begins immediately when the load is connected.

Remember! To ensure that the battery serves you for a long time, regularly check the level of electrolyte it has and top it up if necessary.

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.

Other important selection parameters

Having understood these criteria, go to the device type. The most common maintenance-free models today are:

• Low antimony (Sb);
• Calcium (Ca/Ca);
• Hybrid (Ca/Sb).

Old-style antimony ones are rarely used and are gradually becoming a thing of the past. Here we are talking about the addition of calcium or antimony to lead plates, which increases the performance characteristics of devices.

Make sure that the device has straight polarity.

In terms of dimensions, the option with a length of 241 mm, a width of 175 mm, and a height of 190 mm will come in handy.

When caring about quality, it is not at all necessary to choose an imported product; Russian developments are in no way inferior to foreign ones. batteries “Tyumen Premium”, “Zver”, “AkTech” have proven themselves well

Be careful when connecting the device; if you are doing this for the first time, consult a specialist.

Gel (maintenance-free) battery device

The third type of battery is called gel. The technology is called GEL; in gel batteries, the electrolyte is thickened to a gel-like state with silica gel. There is no way to check the fluid level in them - it is not serviceable. They have a very high electrolyte level above the plates and a density reserve.

One start of the engine takes as much energy from the battery as it receives from the generator in 10-15 minutes at normal speed. In winter the discharge is greater. The battery may not be fully charged if daily trips are short. The generator does not have time to fully charge the battery, so occasionally it is recommended to charge the battery from a charger at home.

In summer you need to check the electrolyte level because the heat causes water to evaporate. It evaporates even when the car is standing. If necessary (if the design allows), distilled water (and only water) should be added.

Battery selection, cost

When choosing this unit for a VAZ 2107 car, it will be necessary to take into account the overall dimensions:

• length, mm – 242;
• width, mm – 175;
• height, mm – 190.

It should be noted that most batteries have exactly these overall dimensions. When purchasing, you need to focus on batteries with straight polarity with a capacity of 50-60 Ah.

There are many different models of rechargeable batteries on sale.

Tips for choosing a car battery.

If you do not want to maintain the battery, then it is recommended to choose a gel battery. If you don’t listen to music with the headlights on for a long time in a car with the engine turned off and there is no current leakage, then it will last at least 4 years and will not let you down in winter.

Before purchasing, check out the latest battery reviews and tests. When purchasing a battery, make sure that it is fresh. If it is filled and charged, then up to 3 months after manufacture, and if dry charged, then up to 6 months.

The price of a battery depends on its type, brand and capacity (average price 2500 - 4000 rubles). You can buy the battery in online stores.
