Facts about Varta/Bosch batteries
Although there is a difference, and it is the price and the warranty period. Varta batteries are a little cheaper in price than the same analogue from Bosch, but the warranty period is 18 months, compared to 24 months for the Bosch battery
Varta batteries have never been produced and are not produced in Ukraine!
If you hear in the market that Varta has spoiled since they began to be assembled in Ukraine, it means that we speak about a fake. Officially Bosch and Varta batteries are produced in Germany, Austria, Belgium, Spain, Czech Republic. Not in Ukraine.
Varta is not like Varta
It is incorrect to speak bad or good about all Varta batteries. The fact that there are 3 main lines:
- Black Dynamic (the most budget-friendly series, designed for a service life of 3 years)
- Blue Dynamic (standard series, for gasoline engines, usually lasts 4-5 years)
- Silver Dynamic (the most top/premium line, for diesel engines, lifetime of more than 6 years)
All of the above batteries have a different amount of lead, different starting characteristics, different price, and therefore compare them incorrectly.
No charge indicator
Most manufacturers refuse from the charge indicator, because of its low information value. After all, the color of the eye depends on the density of the electrolyte in only one of the six cans. In addition, the normal density of the electrolyte does not guarantee that the engine will start. Less and less car owners are ready to look under the hood at least once a month. And consequently the indicator is a thing unclaimed.
Varta and Bosch batteries are maintenance free
Batteries are fully sealed, indestructible, no access to the banks and plates. Certainly it is good to check voltage from time to time, but you can forget about hydrometer.
The country of origin does not matter
As a rule we supply to Ukraine batteries manufactured in Germany, Czech Republic and Spain. After numerous tests and observations we are firmly convinced that there is no difference in quality. Simply the location of factories is different and the weight, starting characteristics, life time do not differ.
The fourth character in the code. year of manufacture
In order to quickly check the year of manufacture of a Varta/Bosch battery, just pay attention to the 4th character in the code embossed on top of the battery cover: the number will indicate the last character in the year of manufacture.
Basic information about Bosch and Vatra
Both the Bosch and Varta brands were founded in Germany under different companies. But the situation changed dramatically in the early 2000s, when the American giant Johnson Controls began to conquer the European market. Subsequently, the Varta brand was fully acquired by an American company, and later the Bosch brand came. Johnson Controls now owns 80 percent of the Bosch brand, and is therefore the majority owner. Although professionals in the field are aware of this fact, some drivers firmly believe that these batteries are produced by different companies and therefore try to demonstrate the superiority of one brand over the other. It also follows that Varta and Bosch batteries are not only produced by the same company, but also at the same factory, using almost identical technology and methods. So, how do we choose: which is better Varta or Bosch battery which brand to choose, if both products are subjected to the same production process in the same company? To do this, we need to look at what both brands offer us and the distinguishing features of both types of batteries.
Big test of 6 car batteries of foreign brands 2021. charge and 20-hour discharge
Hi Hubr! 6 starter batteries in the L2 case will be tested today ❒ Topla Energy ❒ Banner Power Bull ❒ Ista 7 series ❒ Mutlu SFB ❒ Exide Excell ❒ и Varta Standard. They are all made with modern Ca/Ca technology.
only two of the six batteries have open access to the plugs, so let’s review the criteria for determining whether a maintenance-free battery (MF, SMF) with no access to the electrolyte is fully charged, which is the majority on the market today. And let’s also check the repeatability of the Konnwei express tester readings, which some bloggers doubt.
The stated capacities of these batteries are not much, and the cold cranking currents (CCW) vary quite a bit:
- Topla Energy E60H 60 Ah EN 600 A, production 5 week 2021,
- Banner Power Bull 62 Ah EN 550 A, production 17 week 2021,
- Ista 7 series 6ST-60A2 60Ah EN 600A, Week 14 2021,
- Mutlu SFB 60 60 Ah EN 540 A, March 25, 2021,
- Exide Excell EB620 62 Ah EN 540 A, March 2021,
- Varta Standard L2-2 60 Ah EN 520 A, March 2021.
Topla Energy battery has plugs to access the electrolyte. Let’s use this to measure its density.
Density by can was 1.255 to 1.26 kilograms per cubic decimeter. In a 100% charged Topla Energy, it should be 1.29.
Тест аккумуляторных батарей в мороз.18. Какое напряжение аккумулятора в мороз Bosch/VARTA/A-Mega
It is worth recalling that the density of the electrolyte, a solution of sulfuric acid in distilled water, is a measure of the acid concentration. And the acid concentration for a battery with a liquid, free-flowing electrolyte (denoted flooded, WET) is a measure of the level of charge. The point is that during charging, water is absorbed from the electrolyte and acid is released, while during discharging, on the contrary, acid is consumed and water is released.
These are not just side effects, but necessary ingredients of the Gladstone-Tribe dual sulfation equation, the main current-generating reaction of the lead-acid battery. The lack of acid will not allow the oxide to be reduced and the lead to be oxidized to sulfate, and there is no place to get the electrical charge and energy to power the external circuit, (starter, onboard instruments). Lack of water will not allow lead sulfate to be reduced to metal and oxidized to oxide, so the active masses will not take a charge. And the necessary ingredient must be present not somewhere, but directly in the reaction zone. the active mass area. That’s why electrolyte stratification interferes with the battery’s performance.
Another condition for the Gladstone-Tribe reaction is the electrical potential. sufficient to overcome the thermodynamic EMF, and it is with a local excess of acid at the bottom of the cans and in the depths of the packs is highly elevated. For this reason for a full charge with desulfation and electrolyte mixing an increased overvoltage is required, which is not supplied to the battery by most vehicles, and the latter needs a stationary charge every few months.
Batteries must be fully charged before testing, as well as before use. Completely. means, to convert all the lead sulfate into charged active masses (AM). spongy lead of the negative plates and lead oxide of the positive plates, and to equalize the acid concentration in the electrolyte throughout the volume of the cans. If you undercharge the active masses, you lose useful capacity and current capacity, which continue to degrade with every deep or shallow discharge/recharge cycle and every month of operation. This is clearly shown in the article “What kills calcium batteries”. If the electrolyte stratification is not eliminated, it will interfere with rendering of useful energy to the consumer and replenishment of charge from the generator, as it is written above and the results of the tests will be inadequate.
We will charge with domestic Berezhok-V1 Battery Charger in automatic mode. Set the maximum voltage to 18 volts. With such setup the charge is unlikely to complete automatically, so we will observe its progress, which will allow us to make interesting conclusions about the differences of the batteries under study. In contrast to the manual constant current and voltage (CC/CV) charging mode, automatic charging can be monitored less frequently, not every 2 hours but every 12 hours or 2 times a day. Or set the maximum voltage to a lower one, then the automatic rifle will finish the charge.
After the first 12 hours of charge, the maximum voltages at different batteries are different, and the currents at these voltages are also different:
- Topla Energy E60H. 16.1 В, 1.9 А,
- Banner Power Bull. 16.2 В, 1.9 А,
- Ista 7 series 6СТ-60A2. 14.7 В, 0.6 А,
- Mutlu SFB 60. 15.8 В, 1.6 А,
- Exide Excell EB620. 15.9 В, 2.0 А,
- Varta Standard L2-2. 16.2 В 1.5 A.
Twenty-three hours have elapsed since the charge began, the charge parameters are as follows:
- Topla Energy E60H. 16.4 В, 1.9 А, 14.5 Ah,
- Banner Power Bull. 16.6 В, 1.9 А, 14.9 Ah,
- Ista 7 series 6ST-60A2. 15.6 В, 1.5 А, 13.7 Ah,
- Mutlu SFB 60. 16.2 В, 2.0 А, 14.8 Ah,
- Exide Excell EB620. 16.4 В, 2.0 А, 15.5 Ah,
- Varta Standard L2-2. 16.5 В 1.5 A, 12.7 Ah.
- Topla Energy E60H. 16.7 V, (was 16.4), 1.9 А,
- Banner Power Bull. 16.7 В, (16.6), 1.9 А,
- Ista 7 series 6ST-60A2. 16.2 В, (15.6), 1.5 А,
- Mutlu SFB 60. 16.4 В, (16.2), 2.0 А,
- Exide Excell EB620. 16.6 В, (16.4), 2.0 А,
- Varta Standard L2-2. 16.6 В (16.5), 1.5 A.
Took two days of charging. Let’s compare the ampere-hours delivered to the batteries during this time. The automatic charge was made by intermittent asymmetric current with the regulation of the microcontroller in real time, so it is not enough just to multiply the amperes by the clock.
The maximum voltages and currents at them have not changed in 12 hours. This indicates that the charge is complete, it is time to disconnect the charger. For further automatic charging for each battery, you can set this maximum voltage, or a little lower, then the charge will be completed automatically. Don’t forget to consider the temperature: the higher it is, the lower the completion voltage, and vice versa.
Let the batteries stand and measure. After 24 hours of standing time.
The density of the electrolyte in all jars Topla Energy 1.29, in Varta Standard 1 battery.30.
Proceed to check with the tester. Before the charge was:
As we can see all readings were improved. Open-circuit voltages (ORC, also EMF without load) indicate the absence of electrolyte stratification. The health of all batteries, except Topla Energy, is 100%, i.e. the starting current according to the test results is equal to or exceeds the nominal. But it should be noted that of the six 60-62 Ah batteries in question, the THP of 600 amps is claimed only by Topla and Ista, while the other 4 have it from 520 to 550. Let’s weigh the batteries.
The dispenser selects the parameters of the electrolyte mixing stage, following its own algorithm. And what happens if we supply the same current to our 6 accumulators 1.5 A, (i.e., 2.5% of nominal capacity), with no voltage limit? Let’s check. To do this it has a manual CC/CV mode.
The following voltages are set on the battery terminals.
Let’s analyze the data. In the table, yellow indicates low values, indigo. high values:
In terms of nominal ampere per kilogram, the leaders are Ista and Exide, in terms of ampere per kilogram. Ista and Topla. Readings ТХП of the tester of Topla do not reach the nominal value on one and a half percent, but this is within the error of measurement, and the batteries have not passed the test and training cycles (TTC), the first of which is below in the text.
Mutlu and Warta were in the lead in terms of overcharging TCT readings. Both have the lowest rated amps and amperes per kilogram. It is possible to conclude that Mutlu and Varta declared modest parameters, and at the same time have laid good reserve of characteristics.
Ista and Varta needed less ampere hours for recharging, their mixing current was lower. NRDC before charging was higher than the other 4 batteries, which may indicate a higher level of charge. Ista and Mutlu had the lowest completion voltages, indicating less tendency for electrolyte stratification. SFB and Warta Standard have less dense separators than EFB.
The voltage at a current of 2.5% capacity and electrolyte mixing voltage in automatic mode correlate with each other, with the automatic voltage 100-200 millivolts lower, while the current of 4 batteries out of two is higher.
Stirring voltage of Topla and Warta during the first and subsequent 12 hours of charging rose evenly, and for Banner, Mutlu and Exide the increment of this voltage during 12 hours decreased by 2-4 times.
Ista in the first 12 hours did not reach active mixing at all, in the next 12 hours the increment was 600 millivolts, and the mixing voltage stabilized. This behavior often indicates unbalanced or (and) under-molded plates in a new battery, which is not a defect, but exacerbates the importance of proper commissioning.
Ista 7 series, Mutlu SFB 60, Topla Energy E60H and Varta Standard behaved when charged like classic Ca/Ca batteries. At the same time, the plate layout of Warta and Mutlu is denser than Ista and Topla. Banner Power Bull P6219 and Exide Excell EB620. as the batteries are more modernized design with dense separators, with Exide maximum lead savings.
Further performance dynamics we will all see in future CTCs, before which we will put the battery to be stored in buffer mode at 13.1V to prevent self-discharge.
Batteries removed from buffer storage, check them with a 200 amp fork.
Let’s look back at the old KW650 readings.
After buffer storage and plugging, let’s test again.
We see the repeatability of the results. Who said that express testers show weathering on planetary satellites, their boards somehow have the wrong tracks traced, and the software can be driven into variable overflow? If you measure capacitors with them or do anything else outside the range of application, anything is possible. Express-tes for lead-acid automotive starter batteries are designed, oddly enough, to determine the performance parameters of these batteries during their maintenance, and with this task they solve perfectly well.
For discharging according to GOST current of 5% of capacity let’s use chargers Kulon-912.
13th hour of discharging. The voltages on the battery terminals are as follows:
- Topla Energy E60H. 12.0 В,
- Banner Power Bull. 12.1 В,
- Ista 7 series 6ST-60A2. 12.0 В,
- Mutlu SFB 60. 12.1 В,
- Exide Excell EB620. 12.1 В,
- Varta Standard L2-2. 12.05 В.
- Topla Energy E60H. 11.8 V with no load, charge already completed, capacity 58.58,
- Banner Power Bull. 11.6 В,
- Ista 7 series 6ST-60A2. 12.0 V with no load, charge completed, capacity only 50.98 of the claimed 60 Ah,
- Mutlu SFB 60. 11.3 В,
- Exide Excell EB620. 11.4 В,
- Varta Standard L2-2. 11.5 В.
Open up the Varta Standard, comparison with Varta Blue Dynamic (Bosch S4)
The topic of this article was “autopsy” of two popular batteries: the car battery Varta, which comes as standard equipment for cars and has a very good life span (by the way, Varta is the supplier of batteries for almost all car plants, except for Japanese and Korean). Also opened the battery Bosch S4 (who do not know, it is Varta Blue Dynamic, but with stickers for his dealer Bosch Siemens). Both batteries are well past their useful life on the car.
Factory Varta 1J0 915 105 AC has characteristics 60Ah 480 A (En), store. Varta Blue Dynamic (Bosch S4) similar 60Ah 540 A (En). According to the specs on the label, the second one is better. In fact, the “regular” is 2 kg heavier. The factory plastic was also harder to saw 🙂
Both batteries have positive plates forged. Wart’s proprietary “power frame” stamping with a stiffening frame around the perimeter. But the positive plates of the original Varta are noticeably thicker and the grease, despite the age of the battery, is preserved on them (apparently they stick to the cells with wider walls more easily). The battery offered by Warta in the networks is worse. The positive plates are very, very thin, and no linings were found on it. crumbled. The plus plates are packed in the usual plastic envelope separators.
Negative plates are made by punching and stretching method and don’t have stiffening frame on perimeter, as well as own separator envelope. Warta only packs plus plates in envelopes. Again, the plates of the standard Varta are thicker and stronger than the store’s.
The body plastic of an OEM battery is also almost twice as thick as a store battery. The side wall ribs are very small in both, so the sides are almost always blown out.
The factory Varta has plugs and access to the cans, but the store one does not. Also the factory battery is equipped with a charge level indicator peephole.
Output terminal through the plastic cover is realized through 3 rings at the factory and only 2 in a store (the more such rings, the more difficult for the electrolyte to seep out and then leave the white salt on the terminals, so annoying to the owners).
The state of the plates of a 5 year old standard battery is MUCH better than the same age of a store battery. It is possible that the lacquer in the factory battery is additionally reinforced with a special paper or cloth (unfortunately, visual inspection does not help to find out).
In the end, an autopsy once again confirmed the fact that we always tell our customers. original factory Varta and Varta (Bosch) which is sold in commercial networks, they are completely different in quality and, consequently, battery life. Perhaps our pictures do not convey the difference in plate thickness, the linings, the case and the difference in weight. But it is very significant.
Unfortunately, regular Varta can be bought only in official car centers of your car brand and it costs 2.3 times the store price. In our opinion there is no reason to overpay. There are other manufacturers that offer even better batteries at a very reasonable price.

Which battery is better to choose: Varta, Bosch or Rocket?
Bosch is known both as a manufacturer of car parts and as a seller of a countless range of products: from batteries to the most sophisticated equipment. But not all products the company makes itself. The corporation from Germany orders most of the products under its brand from third-party manufacturers. For example, Bosch orders car batteries from Varta. Bosch batteries are manufactured at the Varta plant in the Czech Republic. The battery packs that Bosch sells in Asia are made in South Korea’s Rocket factories.
In Ukraine there are Bosch batteries by Warta. Warranty period 1 to 2 years. In terms of price and quality they are similar to Varta batteries. Why it is better to buy not a Bosch battery in the store read below.
Batteries imported into Ukraine are produced on modern factory Varta in Czech Republic. The warranty period of 1 to 2 years. Warranty depends on the importer’s policy. Varta is the most popular brand of car batteries in the world and the best-selling. The technology used to manufacture Varta batteries for Dynamic (Black, Blue, Silver) Ca/Ca. These are ordinary budget calcium batteries. Consumers mistakenly believe that Silver Series batteries have silver in the plates 🙂 There is no silver. In the budget Vartovsky series of speakers (and series Bosch S3, S4, S5) only positive plates are made by PowerFrame technology, and the negative is the usual mesh sawing and stretching (“chain-link”). cheap budget batteries are made with this technology). But the price of Warta batteries is far from cheap. Service life of Varta Dynamic batteries 3-4 years. Batteries with a small capacity of 35-45 Ah have a shorter life: 2-3 years.
Warta is the battery supplier of choice for AUDI and Mercedes. However, in factories and service networks of car brands Varta offers a completely different battery. All plates in them are made by PowerFrame technology (strong, forged, with thicker edges). For example, weighs such Varta 60Ah 16.5 kg, and a budget Varta Blue Dynamic 60 Ah about 14 kg. These “real Varta” serve for a very long time (7-8 years). Owners of Skoda, VW, Audi, Mercedes cars which used to use the state-operated Varta for so long run to the store and order “Varta only”. Buy Varta Dynamic and. And this is not the same Varta 🙁 In Ukraine demand in batteries Varta Blue Dynamic of Asian standard JIS.
Reliable Rocket batteries
Production of Rocket batteries is located in South Korea. Rocket is one of the five most popular batteries in the world. The warranty period for it in Ukraine is 1.5 years (although in Europe the manufacturer gives 3 years warranty). In fact, the brand is Japanese-South Korean, a joint venture with the Japanese holding Yuasa Co. Rocket batteries are made using an improved modification of calcium technology: Ca/Sn (calcium-tin). All plates are made on PowerFrame technology. Rockets. is quality in every detail. Strong and reliable body, modern composite current leads, impurity-free electrolyte, high-purity lead. All joints, current leads, separators are made of the most reliable materials. According to the statistics of Rocket supplier to Ukraine these batteries have the lowest percentage of returns under warranty. Rocket is a supplier of factory produced batteries for Kia, Hyundai, SsangYong, DAEWOO brands. As experience of Ukrainian drivers shows average lifetime of Rockets is from 6 to 7 years. There are record-breakers, which lived up to 8 and even 10 years!
Two features of Roket batteries in Ukraine are in two models, which have no analogues from Varta and Bosch:
The Rocket SMF 75D23L (65Ah, EN 580 A) has the highest capacity in the most popular Asian size 232 x 173 x 225 mm (LxWxV)
Battery Rocket SMF 75B24LS (55Ah, EN 470 A) has also the largest capacity in the size of 239x129x225 mm (LxWh). Battery for Honda Accord.
What to choose? We advise to use pragmatic approach: find out the date of manufacture of the battery, compare and warranty periods, make sure that there is a warranty center of the brand in your city.

Differences between Varta and Bosch car batteries
We begin with the fact that this publication is constantly being corrected and supplemented by various subtleties in the understanding of the legendary batteries of brands Varta and Bosch. Certainly many of you, opening our publication, have thought about why we have combined in one publication exactly two brands Varta and Bosch? The answer is very simple for more than 5 years, or maybe more, Varta and Bosch batteries do not differ from each other, they are the same product, which differs only in the design of the label. They really are no different. Same dimensions, same starting currents, same manufacturing technology, but the labels are different and the internal catalog number is different. Varta batteries are conventionally divided into 3 classes (more than 3 classes the other classes are innovations):
Exactly the same Bosch batteries are conditionally subdivided into 3 classes (more than 3 classes the other classes are innovations):
To simplify further writing of this review, the classes of Varta and Bosch for logical perception can be compared as follows:
That’s the way it is. Very often you can hear from a customer who called us that he only wants to order the battery Varta, or after a certain period of time you can hear from another customer. the desire to buy only Bosch. In the process of selling batteries, our online store AKBSET, constantly keeps control of the fact that the ordered battery was fresh. In such cases, when we offer a cardinally-minded caller to buy Bosch instead of Varta or vice versa instead of Bosch to buy Varta, based on the fact that this or that battery is more recent release date misunderstanding on the part of the buyer occurs, that the batteries are the same. And it is so. Accordingly, the factories of manufacturers are also one. Varta and Bosch batteries are manufactured in the following countries:
Here it is necessary not to forget to focus your attention on the fact that there is a rumor that Varta and Bosch batteries are manufactured in Ukraine.Dnepropetrovsk (one buyer was so confident in the speculation that he even voiced the address in the city where they allegedly produce them) or this version of the speculation that they are made in China and even heard that we near Kiev. Varta and Bosch batteries are made only in the following countries: Germany, Czech Republic, Sweden, Austria, France, Spain. And Ukraine is supplied only from Czech Republic.
And now we will dwell on each series of Varta and Bosch batteries
The official site of Varta and Bosch trademarks writes the following:
For cars with basic electrical equipment, you may need less battery power. However, they still need excellent starting power, continuous performance and absolute reliability. Varta Black Dynamic Batteries (Bosch S3 Batteries) offers you all of this as a tried and trusted solution that delivers quality at a reasonable price.
- Designed for vehicles with less demanding power requirements
- 100% cold cranking power
- PowerFrame technology® for exceptional performance
- Meets the requirements for OE
In our words it can be explained that Varta Black Dynamic Batteries (Bosch S3 Batteries). These are batteries that are designed to last for three years. They have starting currents corresponding to only gasoline engine cars and as a conclusion if the buyer is configured to buy only Varta or Bosch batteries, and since these batteries are budget-friendly, they will always fit the limited budget of the buyer, while fully satisfying the desire to have these batteries installed in your car.
The official website of the Varta and Bosch brands says the following:
You are looking for a solid all-rounder? Take a look at Varta Blue Dynamic batteries. Our best-selling replacement battery meets OE specifications, provides best-in-class starting power and cold start power, and features a high charging capacity. This high quality product is the ideal solution for every vehicle class.
- Designed for all vehicle classes
- Optimal cold cranking currents of up to 110% compared to conventional batteries
- PowerFrame technology®
- Meets OE requirements
In our words it can be explained that Varta Blue Dynamic Batteries → Bosch S4 batteries. are batteries that are designed to last for four years. They have starting currents to match those of gasoline-powered cars with lots of appliances. The prestige of these batteries corresponds to the prestige of an upper-middle class car, where they do not have intermittent charging from the alternator.
The official website of the Varta and Bosch brands says the following:
High-performance vehicles with a lot of equipment require a lot from their battery. That’s where our superior Varta Silver Dynamic batteries come in. It is extremely reliable, meets or even exceeds all requirements for EO and is characterized by excellent cold starting power. In short, a premium lead-acid battery that you can always rely on.
- Designed for high-performance vehicles with extremely high energy requirements
- Exceptional cold cranking currents of up to 122%
- PowerFrame technology that delivers exceptional performance
- Exceeds EO requirements
In our words it can be explained by the fact that the Varta Silver Dynamic batteries → Bosch S5 batteries. are batteries that are designed to last for five years. They have starting currents corresponding to petrol and mainly diesel engines with a large number of consuming appliances. The prestige of these batteries corresponds to that of an up-medium car, where they do not have intermittent alternator charging.
Varta and Bosch batteries are currently the leaders in the battery market. The quality is excellent. But what about the disadvantages? Based on our sales experience with these batteries, we’ve reached a consensus that they have one drawback. batteries are completely maintenance free. Two or three heavy discharges of a Varta or Bosch battery causes the battery to fail completely and cannot be repaired. The creators of these batteries decided that these batteries will only stand on modern cars where all the fuses will not allow a strong discharge of the battery. Accordingly, we do not recommend installing Varta or Bosch on domestic cars more than 10 years old.
Well, that’s all for now. As we go along, we will continually add interesting information about these batteries as we get more and more interesting thoughts and facts.
Varta Blue Speaker (or Bosch S4)
Buying a Varta Blue Speaker battery (Bosch S4) is the most common and versatile solution for many car owners. The battery meets OE requirements, has a solid starting power, belongs to the medium cost class, has a good cold start power, is famous for its good charge capacity. The model was specifically designed for cars of all classes, making it versatile. Optimal cold cranking current corresponds to 110%. PowerFrame technology is used.
Service life. 4 years on average. Suitable for gasoline-powered cars with high electricity consumption.
I can say that some friends had these batteries worked from 5 to 7 years, which is a very good figure for the price and in fact it is an indicator of quality Turkish company. Pros and cons of MUTLU:
The main advantages of the Bosch batteries are the high energy characteristics, which allow to work perfectly in the cars stuffed with electronics and having powerful engines. By the way Bosch batteries are made in the same factories as VARTA. Bosch has production in China, but it only goes to the domestic market and other countries do not deliver their trinkets.
In my experience I can say that I bought an Octavia Tour 1.I had a VARTA 8 Turbo on my car for over 8 years and the battery in my case was damaged by a leakage current. Currently it is 12 years old and has no problem to run an old VAZ 2109 at my friend’s place. I tried to find the same battery by the code on it, but they just don’t have them in the store.
How do Bosch batteries differ from Varta?
Sooner or later every car owner asks himself this question. Both brands are well known. Both deserve the best reviews and recommendations. So which one to choose??
Varta and Bosch are the leading German brands, each with more than 100 years of history. Warta specializes exclusively in the manufacture of batteries, while Bosch is mainly known as a manufacturer of household appliances and power tools.
Something to be aware of
Varta batteries are manufactured at Johnson Controls, which also places orders for batteries from the German company Bosch.
Yes, you are not mistaken. Both brands are made in the same manufacturing facilities using the same technology.
In fact, there is little difference between the two brands. And this means that the choice depends entirely on the exact battery required for your car in terms of technical characteristics.
Advantages and disadvantages of Bosch and Warta
If you set yourself the goal of determining which one of these batteries is better, you will spend a lot of time, but you will not make a concrete conclusion.
Bosch is considered an ultra-reliable battery that requires virtually no maintenance. In this mass of praise on forums and in car magazines there are notes about its rapid discharge, even with infrequent use of the car.
Varta according to the reviews is as good as Bosch, but its main advantage, as noted by motorists, is almost 100% reliability in severe frost. Although negative reviews also occur.
The only conclusion that can be made is that Bosch and Varta batteries do not differ in their technical and operational characteristics.
The answer is simple: choose a battery that suits the characteristics of your car, produced no later than 1 year ago and is available from the seller.
In terms of cost Bosch and Varta are approximately equal, in terms of performance tests. also differ slightly. The warranty is the same.
And this means that the question of choice is irrelevant. And there is no point in looking for a similar Varta, if there is a suitable Bosch in stock.
