Which battery is better varta or Bosch

best car batteries

There can be many reasons to look for a new battery for your car. The main extreme wear and tear or failure of the old one: constantly removing the battery for recharging or cigarette lighter car in the morning people quickly get bored. With the modification of the car often have to install an additional battery or more capacity to replace the regular it is necessary to power the winch off-road or a powerful audio system of the show car. The best car batteries 2020-2021 are presented in our rating.

What you need to know when choosing a battery? First, variations in its design:

  • Lead-acid batteries are the simplest and oldest type. They consist of six cans, in which the lead plates are immersed in a solution of sulphuric acid. Such batteries are cheap, and the possibility of replacing the electrolyte allows to reanimate them in some cases. Some models, however, are available as maintenance-free versions (no unscrewing of the jar caps). They are resistant to overcharge, but in a deep discharge can irreversibly lose capacity or stop collecting a charge altogether (plate degradation occurs).
  • Gel batteries use acid thickened with silicon compounds instead of liquid electrolyte. Because of this, they are not only sealed, but also continue to work at any angle of inclination. Gel batteries are able to survive deep discharges, but are more demanding of the charging conditions. In addition, their price is the highest.
  • AGM batteries combine elements of both standard and gel batteries: they use a liquid electrolyte that impregnates the filler (usually fiberglass) between the plates. They can operate virtually at any inclination (upside down is not recommended). AGM batteries are resistant to vibration, because the filler does not allow the plates to disintegrate. But unlike conventional and gel batteries, they are sensitive to both deep discharge and overcharge at the same time.

For an old car the best option is a cheap lead-acid battery. The owner of a new car, who has no reason to fear the generator failure, may be advised to use AGM technology battery: despite the demanding conditions of the charge / discharge cycle, it will provide a higher starting current and rapid recovery charge. Gel batteries, on the other hand, are most often used in car tuning because of their high price. Due to the high current output and tolerance of heavy discharge, they are often used to power powerful audio systems (the regular battery is responsible for powering the car’s basic electrics).

It is also necessary to know the polarity of the battery, i.e. the order of the terminals on its body. Most car models have power leads that are too short or awkwardly positioned for the wrong type of battery. If you turn the battery with its terminals facing you, the positive terminal is on the left of a straight battery (Russian polarity) and on the right of a reversed battery (European polarity).

The starting current of a battery indicated on its label may be measured according to different methods:

  • EN (European method of measurement): the maximum current which a battery can deliver in 10 seconds at a temperature of over 180 degrees Fahrenheit is measured.18˚C at a voltage of at least 7.5 V;
  • DIN (German industry standard): at the same temperature, measure the average current for 30 seconds, and the voltage must not drop below 9 V
  • SAE (American standard): the current is measured at.18˚C for 30 seconds, maximum voltage drop of 7.2V.

As can be seen from this description, the most stringent method of measurement standard DIN (battery, issuing current 365A on DIN, according to the method of EN will be labeled 600A). Choosing a battery, you should be guided by this indicator, which will allow you to count on a confident start in winter.

Since car batteries within the same product line can have different polarity, capacity and price, we will base our rating on the most demanded option: batteries with a capacity of 55 to 70 Ah.

Which battery to choose: VARTA or MUTLU?

Most of the well-known manufacturers of modern batteries use innovative technology, among which only a tenth meet high standards. That’s why the quality of batteries manufactured by new companies (which have not had time to prove themselves in their home market) is often equalized with the equipment of brands that gained wide popularity half a century ago.

Consumers often face the question: what brand of battery to buy if they seem to be identical in quality? In this article we will help you to understand this question by taking as a basis for reasoning the two most popular batteries in our country. VARTA and Mutlu. Many experienced automobile enthusiasts will ask themselves a question: why exactly the Turkish Mutlu, if VARTA and Bosch are leading foreign brands?? The answer is simple: VARTA and Bosch, presented in Russia, are produced at the same plants and factories, differing between themselves only label. Mutlu, on the other hand, is an independent manufacturer that not only has good reviews and a reputation, but also bounces between standard and luxury batteries.

Bosch batteries

The German company Bosch, in my opinion, is a leader in the manufacture of batteries. They used to make their products only in Germany, now increasingly in other countries such as the Czech Republic, Italy, Spain, France, and even Taiwan and China. As the manufacturer assures himself, the quality is not affected and the battery everywhere at the same level (that is, at a high level of production).

Now producing mostly maintenance-free options, there are even with the addition of silver (which you can read here). As well as AGM and EFB

They cannot be called cheap, there is a lot of overpayment for the brand, and the quality is appropriate

Average Depending on the model and warranty (cheap ones 1 year, expensive ones 3 years)

There is no need to be afraid to choose them. My friends have been having these types of batteries for 6 to 7 years and haven’t had any major problems.


The products of this brand are manufactured by Hyundai Sungwoo Automotive Korea in South Korea. The company opened in 1979. It is popular as a major vehicle parts manufacturer, has its own R&D center and supplies its products to Toyota, Kia, Nissan, Hyundai, Honda and General Motors car plants.

Solite batteries, made for cars and trucks, are exported to Europe, Asia and America. They have both modern and proven technologies:

  • Lead alloys with calcium, silver and other metals that increase current efficiency, charging rate, reduce water consumption;
  • Innovative terminals and a special type of current collector that protects the battery from vibration and extends its life;
  • CMF, AGM and gel electrolyte.

All batteries are maintenance free. Approximate number of models for cars is 43, for trucks 7 units. Capacity of battery for passenger cars from 44 to 110A·h, cold cranking currents from 350 to 850 A. For trucks, the characteristics of the battery is, respectively, 110-220A·h and 900-1315 A.

These batteries are produced by a Russian company with the same name, founded in 2001 in Zhigulyovsk. Its development was promoted by the world famous battery manufacturers TUDOR and VARTA.

The range consists of several lines:

  • AKOM starter batteries. Capacities for passenger cars 55-100A·h, starting current 460-870 A. Available in 18 models with products for trucks and Asian cars.
  • EFB newest batteries with double life and increased currents. They are not afraid of deep discharge and corrosion on the plates. Capacity 55-100A·h, currents 530-930A. All seven models are made for premium cars with Start-Stop.
  • Ultimatum line of EFB batteries for machines with Start-Stop system, high consumption. These batteries are designed for cars, yachts and boats, characterized by resistance to discharges. Three models are produced with capacities of 60-95A·h and starting currents 550-850A.
  • Bravo batteries for cars with a standard set of consumers. Available in four models for cars and two models for trucks. Capacities 55-90A·h and 140-190A·ч. Currents are 430-760 A and 890-1100 A respectively.
  • Reactor the most powerful batteries for cars with a lot of consumers. Capacities in five models range from 55 to 100A·The battery has a high starting current of 550-1000A. These batteries have no equivalents in Russia.

Reviews about batteries Varta, Bosch, A-Mega. what is the lifetime

Most people, before buying the desired battery model, will definitely look through the reviews about it on the Internet. This is correct, as it allows you to get information directly from the consumer. But there is an important nuance! Psychologists say that a person satisfied with the purchase, will share his joy with only 1-3 people, and a person dissatisfied will share his misfortune with 50 listeners.

That’s why there is so much negativity on the Internet, especially on the forums. Although in reality the situation is different.

Аккумулятор Bosch S5 Silver Plus 100Ah или Аккумулятор varta silver dynamic 100ah какой выбрать??

Hundreds of used batteries have passed through our collection point for recycling. Based on real experience, AKB-OIL service will also try to make a kind of review-recommendation for those who want to buy a battery in the near future.

Varta and Bosch.Both brands are produced in the same factories owned by Varta. The quality is identical and very high. Batteries are imported to Ukraine from the Varta plant in the Czech Republic. The equipment, on which the battery is made, is made in Germany, USA and Italy. Modern battery production takes place with almost no human involvement. Therefore, the quality of manufacturing plates, assembling and charging is the same at all plants: Germany, Spain, France and the Czech Republic.

The older Varta Silver and Bosch S5 premium batteries that we have recycled have been in working condition for 6 to 8 years. Batteries of these brands that we encountered, under 6 years old were in working condition. We draw your attention that the long-livers were exactly the batteries from premium lines. The Bosch S3, Bosch S4, Varta Black, Varta Blue models were seldom found in the age over 6 years and in good condition.

Customers that gave us their old A-Mega batteries. Bought a new A-Mega Premium The old batteries were 5-6 years old and almost all were in working condition. We have a 7 year old Amega in our office. Its performance is only 20% less than new.

The leaders of the battery ratings were both long-lived. These batteries belong to the premium ranges of world-renowned brands. Among batteries used more than 7 years: Delkor, Bosch S5, Varta Silver.

Batteries from the average price segment were mostly handed over to us at 3-5 years old. Brand names. Mutlu, Ista, Westa. Some of them were in working condition.

Batteries from unknown manufacturers, came to us in the worst condition, broken with leaking electrolyte. These batteries lasted 1-2 years.

The fact that we have examined and tested almost every old battery submitted to us for recycling, allows us to make the following conclusions:

Test of 10 battery packs: electric duos

You want to have a modern battery under the hood of your car, which is not afraid of deep discharges, quietly gives high currents, well receives a charge and has excellent durablility?

Kudos to the skeptics who understand: such battery will be twice as expensive as the usual one, and at such a price all the listed advantages fade, requiring more careful bookkeeping. This is what we decided to do.

For the study we chose brands that offer two types of batteries. the so-called AGM (with absorbed electrolyte), which have all of the above properties, and conventional batteries. And we were looking for batteries in the European version, with dimensions of 242×175×190 mm. These are installed, for example, in Volkswagen-Polo, Skoda-Rapid, all LADA cars, etc. п.

There are five such duos. trademarks Banner, Bosch, Varta, Deca and Mall. All the products were purchased by the editorial board in cash in retail stores.

Cheaper battery?

At first, the search for the cheapest batteries of the most popular size 242×175×190 mm gave a modest result. only five products with ranging from 2610 for the Podolsk battery to 3002 for the Tyumen battery. Not enough for a full-fledged expertise. The price level was raised to 3500. six more batteries were added. And what without the big foreign names. Varta, Bosch, Mutlu? In addition, left overboard and close to them in price domestic batteries. for example, AkTech. By the way, it turned out that some eastern brands have not set “crisis” for their products: the most expensive battery was not at all Bosch, but the Korean Solite battery for as much as 5000!

We ended up with two dozen batteries. Let’s see how the price is related to ampere-hours and pendants.

The purchase was made at a retailer in April-May 2016. The results apply only to this sample and cannot serve as a basis for evaluating all products of this or that brand.


Reserve capacity. Shows how long the car will last with all power consumers turned on (headlights, wipers, ventilation system), if its generator is ruined. Measured in minutes. The higher the result, the better.

Present energy of start-up with stated current. Characterizes the battery’s energy in cranking mode. Measured in kilojoules. The higher the result, the better.

Reduced single current starting energy at.18 and.29 °C. Compares the current-starting characteristics of all batteries under the same conditions regardless of their rating data. Simply put, the higher the energy, the more attempts, all other things being equal, to start the motor with confidence. Measured in kilojoules. The higher the result, the better.

Charge acceptance at constant external voltage. Shows the ability of a battery to recover from a deep discharge. In practice, the battery that takes a charge best will recharge faster, even when travelling. All batteries passed the test.

Note. Technical measurements were carried out by specialists of Scientific-Research Center of AT 3 Central Research Institute of Ministry of Defense of Russia. The test results refer to a specific sample of batteries and can not serve as a characteristic of the whole product of the same name.

Battery test. cold start

Starter batteries are some of the most stressed components in a car. In vehicles with advanced comfort features, fuel-saving technologies and advanced on-board electronics, batteries should allow for a little more. Machines that have a stop-and-go system need a battery that provides as much power as possible for as long as possible. And with a charging system in place when braking, t.е. In order to regenerate energy, the batteries must be able to withstand frequent discharging and charging.

The so-called AGM (Absorbent Glass Mat) batteries made of absorbent glass fiber can do these tasks better than conventional lead-acid batteries. This is why modern car manufacturers often use AGM batteries. Older cars or those that were not designed for AGM technology, must be equipped with an additional conventional battery, because AGM batteries have high demands on the charging system.

For the test, 4 AGM batteries and 6 normal batteries were selected. All batteries provide a capacity range of 70 to 77 Ah and are optimal for small cars or compact cars a la VW Polo, Golf and others. The of batteries vary greatly: while conventional batteries cost between 95 and 163 euros, AGM batteries. from 160 to 269 Euro.

For objective evaluation, all candidates were tested on a special stand. Capacity and deep-discharge behavior were measured. Already here there were noticeable differences. If none of the standard batteries did not reach their rated capacity after a full discharge, the AGM batteries succeeded in this quite well, and two of them even with the maximum number of points.

If the battery has already weakened, it tends to fail in the cold. To simulate winter conditions, a freezer was used with a temperature of.20 degrees Celsius. After 12 hours spent in the Siberian frost, the candidates went to the next stage of testing. the cold start. Once again, the AGM batteries impressed by their power and durability: Banner. 33 starts, Varta. 32, Exide. 31 and Moll. 24. Conventional batteries were weaker: Varta. 23 starts, Exide and Sonnenschein. 19, Moll. 15, Banner and Bosch. 14. Nevertheless these results are quite acceptable for the simulated harsh conditions.

AGM batteries Moll and Banner still had 87 and 79 percent capacity, respectively, after cold starts. The cheaper lead-acid ones had a capacity of 61 percent Sonnenschein and 58 percent Exide. Behind all of them was Moll.

Another important stage of the test. battery life. This was based on the number of charge-discharge cycles a battery can endure. Here again AGM batteries were unsurpassed. After 60 cycles, the Moll AGM provided more than 65 amp-hours, which corresponded to 93 percent of rated capacity. Then came Banner AGM 61 Ah and 87% of rated capacity. Among the conventional lead-acid batteries, the Varta Silver with 49 Ah and 64% of rated capacity and Exide Premium with 47 Ah and 63% performed well. Last place for Bosch and Moll. 35 and 36 Ah, respectively. Nevertheless, even these are acceptable results.

Among the advantages of AGM batteries is the maximum possible number of discharge/recharge cycles. All four candidates received the maximum number of points. In the endurance test. due to the continuous current consumption, simulating accidentally forgotten lights on, Moll and Banner stood out in the AGM segment. Among conventional batteries, Exide Premium and Varta Silver showed good results. Last place went to Banner Starting Bull, which surrendered 2.3 hours earlier than the winner Exide Premium.

Battery expertise: four Russian vs. six imported batteries

It looks like conventional battery packs will continue to rule the roost for a long time to come. Until recently, we predicted that they will be replaced by more advanced batteries made by AGM technology. But due to economic reasons, manufacturers have decided not to replace all of the old batteries with more advanced ones. The inexpediency of such a switch-over was confirmed by the results of our special test, where we compared five different types of batteries.

Therefore, for the traditional annual examination we bought “European” with liquid electrolyte and dimensions of 278 × 175 × 190 mm. These batteries are among the most popular in Russia, they are suitable for most budget cars, as well as for models priced in several million.

Usually we assembled a larger company, but this time we decided not to take “whipping boys”. But along with well-known brands there is a newcomer. South Korean Cene battery. It is made at the same plant Delkor, which produces batteries Medalist, which have repeatedly won in our tests. Today batteries Medalist also produced in Turkey, but in our test we have present namely the Korean products. So, four “Russians” against six “foreigners”. The cheapest battery is the one from Tyumen: 4,000. The most expensive is the Korean Cene: 7300.

The basis of the test program is to check the energy capabilities of batteries at.18 and.29 °C. For the Russian operating conditions these are the most important indicators. In addition, we evaluated the reserve capacity of all batteries, both in the delivery state and after a full charge. The first parameter indicates the integrity of the seller: all the batteries were sold as under warranty, but that does not mean that someone took care of them. The second parameter is the real power reserve of the battery, which we took into consideration when allocating the places. In total, we checked four energy indicators.

For the sake of interest, we compared the ability of batteries to accept the charging current, evaluating their recovery after a deep discharge. And to estimate a benefit from purchasing one or another battery we recalculated scores of batteries taking into account their price. we got a new table of ranks according to price and quality ratio.
