With Start-Stop: versions with automatic engine stop-start, or that leave the factory with an EFB or AGM battery. Ah = capacity; A = cold cranking current (EN standard); + right/+ left = side of the positive terminal. Under each engine you will find its engine codes, handy for identifying your version.

## What you should know about the Mercedes C-Class W204

The C-Class W204 includes the saloon, Estate and Coupé. Versions with Start-Stop or a factory-fitted AGM battery use an 80 Ah AGM in an L4 case or a 70 Ah one in an L3; many of the CDI diesels without Start-Stop need a large conventional battery, 100 Ah in an L5 case, and the petrol engines one of 74 or 77 Ah in an L3. Given the size of some of its batteries, confirm the case before you buy.
- Model fact: the Mercedes C-Class W204 mainly uses case sizes L4 (315 × 175 × 190 mm), L3 (278 × 175 × 190 mm) and L5 (353 × 175 × 190 mm). A battery of a different size will not sit securely in the car’s battery tray.
- General tip: if your car came from the factory with an AGM battery, replace it with another AGM; if it has an EFB, with an EFB or an AGM. A conventional battery in a Start-Stop car wears out much sooner and the system may stop working.
- General tip: on many Start-Stop cars the ECU manages battery charging, so when you replace the battery it is best to register the new one with a diagnostic tool.
- General tip: mid-size and executive saloons keep drawing power while parked (alarm, telematics, comfort systems). If the car goes weeks without being driven, a battery maintainer will extend the life of the battery.

## Frequently asked questions

### Which battery does the Mercedes C-Class (W204, 2007-2014) take?

With Start-Stop, the Mercedes C-Class (W204, 2007-2014) usually takes a battery like the Varta A6: AGM, 80 Ah and 800 A, in case size L4. Versions without Start-Stop take the Varta H3 (conventional, 100 Ah and 830 A); the table shows the battery for each engine.

### Can I fit a standard battery in my Mercedes C-Class with Start-Stop?

It is not recommended. If it came from the factory with an AGM battery, such as the Varta A6, the replacement should also be AGM: with an EFB or a conventional battery it wears out sooner and the Start-Stop system may stop working.

### What size battery does the Mercedes C-Class take?

Depending on the engine, the Mercedes C-Class W204 uses these case sizes: L4 (315 × 175 × 190 mm), L3 (278 × 175 × 190 mm) and L5 (353 × 175 × 190 mm); dimensions are length × width × height. Also check that the positive terminal is on the same side as on your current battery.

### Does the Varta A6 fit the Mercedes C-Class W204?

Yes, it is one of the recommended batteries for the Mercedes C-Class W204 with the C 63 AMG, C 180 CDI, C 200 CDI, C 200 CGI, C 220 CDI and C 220 CDI 4-matic engines (16 of the 30 engines in the table). For the others, check their row in the table or search by number plate.

### How do I find out exactly which battery my Mercedes C-Class takes?

Enter your number plate or chassis number (VIN) in our battery finder: it identifies the exact engine and shows you only the compatible batteries. You can also check the label on your current battery: capacity (Ah), cold cranking (A, EN standard) and technology (AGM, EFB or conventional).
