What types of car battery are there?
The right choice of battery depends on the vehicle and usage. Here are the most important differences between the various batteries:
Battery type
Advantages
Disadvantages
Recommendation:
Lead-acid
Inexpensive, reliable, perfect for older vehicles
Low cycle stability, not for start-stop systems
Conventional cars without lots of electronics, infrequent drivers
EFB
Better cycle stability than lead-acid, cheaper than AGM
Not suitable for regenerative systems

Motorhomes, boats, solar systems
The number of new registrations of combustion engines with start-stop systems in Germany has increased in recent years. This is why EFB and AGM batteries are becoming more important than classic lead-acid models. The cells of these modern battery types are specially designed to withstand frequent charge cycles and better survive deep discharge.
Conclusion: the right car battery for every need - our recommendations 2026
After our comparison, we can make the following recommendations. Brands such as Varta, Bosch, and Exide are often cited as the most recommended car battery brands and score highly with their long service life and reliable performance.
EFB batteries are well suited for cars without a start-stop system and offer a longer service life compared to conventional lead-acid batteries.
AGM car battery for short journeys: The VARTA E39 Silver Dynamic AGM is a top product. With 8.7 out of 10 points, it stands out for its outstanding performance, long service life, and reliability, even on short journeys. The investment is worthwhile for modern vehicles. It easily copes with the increased load caused by frequent starts and offers maximum durability.
Ideal car battery for simple start-stop systems: The EXIDE EL600 EFB offers good value for money for simple start-stop systems. With 8.2 points, it is significantly better than standard batteries and cheaper than AGM models. The energy supply process remains stable even with frequent stops.
Recommended budget car battery: The RIDEX 1S0009 offers solid performance for the price. Anyone looking for an affordable solution for older vehicles without special requirements will find a fair offer here.
Good car battery for traditional cars: The BOSCH S4 002 scored 8.6 points for reliability and fair pricing. The ideal choice for vehicles without a start-stop function.
Car battery for high energy requirements: The Continental L3 with an 80 Ah capacity and 750 A cold cranking power is perfect for diesel engines and vehicles with many consumers. The price-performance ratio is just right.
When buying a new battery you should consider several factors. Firstly, the battery type is crucial: does your vehicle have a start-stop system? Then you need at least an EFB battery, perhaps even an AGM car battery. Conventional vehicles get by with standard lead-acid batteries.
The capacity, measured in Ah, must also match your vehicle. The operating manual provides information on the required capacity. Batteries that are too small are quickly overstrained, while batteries that are too large bring no advantage and only cost more.
On the other hand, the cold start performance (cold cranking amps) is particularly important in winter. Diesel engines require higher amps than petrol engines.
Make sure the battery has the correct dimensions (DIN/ISO size) and pole arrangement. A pole 0 layout means that the positive pole is on the right when viewed from the front, a pole 1 layout is when the positive pole is on the left. The base hold-down design (B00, B13 etc.) must match the mounting bracket in the vehicle. Looking through the operating instructions or at the old battery will help.
The service life of a battery is typically 4 to 7 years. With frequent short journeys, extreme temperatures, or many electrical consumers, it may be shorter, especially if it is not designed for such loads. AGM batteries last significantly longer than standard models under the same conditions and offer better performance.
Installing a battery is generally doable even for non-professionals. Important: disconnect the negative terminal first, then the positive terminal. Reverse order when connecting: positive terminal first, then the negative terminal. In modern vehicles with start-stop systems, the new battery often has to be reprogrammed in the control unit. In this case it is advisable to visit a garage. The process only takes a few minutes.
As far as the costs are concerned: standard lead-acid batteries are available from around €70, EFB models cost between €90 and €130, and AGM batteries cost between €130 and €210. Lithium-ion batteries for special applications can cost several hundred euros. At AUTODOC you will find over 6.7 million spare parts from around 2,500 brands, including the right battery for your vehicle at a fair price.
Tip from the AUTODOC mechanic: The battery should be tested at least once a year before winter. You can also carry out the test yourself at home using a multimeter. If the voltage is below 12.4 V with the engine switched off, the battery should be replaced soon. It is not advisable to wait until the first starting issues in winter. Discharged batteries are a common cause of breakdowns.
Which car batteries are popular for the respective vehicle brands?
The requirements for the battery vary depending on the vehicle manufacturer and model. Here are recommendations for popular brands:
Starter battery for VW: For newer models with start-stop systems, an AGM battery, such as the VARTA E39, is recommended. For older ones, standard units like the BOSCH S4 002 battery.
Starter battery for BMW: It’s better to use AGM. Battery management reprogramming is usually required.
A fully charged conventional car battery should have 12.6 to 12.7 V when resting. An AGM battery has a slightly higher voltage of up to 12.9 V. Anything below 12.4 V and the battery is considered partially discharged, whereas when below 12 V it is deeply discharged and should be recharged or replaced as soon as possible.
Disconnecting the car battery: which order?
When disconnecting, first disconnect the negative terminal (black cable), then the positive terminal (red cable). This sequence prevents short circuits and protects the vehicle's electronics from damage.
Which car battery lasts the longest?
AGM batteries last the longest, especially for short journeys and start-stop operation. They can withstand up to three times more charging cycles than standard lead-acid batteries and often achieve a service life of six to eight years.
Connecting the car battery: which order?
When connecting the unit, first connect the positive terminal (red cable), then the negative terminal (black cable). This order, which is the reverse order of disconnection, is important for safely installing the battery.
Which car battery is better? Varta or Bosch?
Both brands deliver top quality. The choice depends on the specific model and vehicle and the buyer's preferences.
Which acid is in car batteries?
Diluted sulphuric acid (H₂SO₄) with an acid content of around 37% is used in lead-acid batteries. In AGM and EFB batteries, the acid is bound in fibre/fleece mats, which prevents leakage and offers greater safety.
What is the capacity of a car battery?
The capacity varies depending on the vehicle type: small cars require around 40–60 Ah, medium size cars 60–75 Ah, and larger vehicles 75–100 Ah. Diesel and vehicles with start-stop systems require higher capacities than comparable petrol engines.
Which oxides are in car batteries?
Car batteries usually contain lead dioxide (PbO₂) on the positive plate and porous lead (Pb) on the negative plate. Lead sulphate and water are produced during discharge, whereas lithium oxides are used in lithium-ion batteries.
