## How to know which battery your MERCEDES-BENZ M-Class takes

The quickest and safest route is to enter your number plate: we identify the exact version, its engine and the battery fitted at the factory, with no room for error.

Prefer to do it manually? Check the date of first registration on your V5C and match it against the generation table above. When a year straddles two generations, the body style decides it: five-door hatch, estate or coupé.

One last check: the label on the fitted battery gives you the reference capacity and cold cranking. Match or improve those numbers, and make sure the case size and polarity suit your battery tray.

## Start-Stop: which battery your M-Class needs

Start-Stop on the modern M-Class changes the rules: the battery takes hundreds of micro-cycles daily. The correct answer is EFB for basic systems and AGM where braking energy is recovered. Dropping to a conventional battery is the most expensive mistake you can make here.

## Frequently asked questions

### Which battery does a MERCEDES-BENZ M-Class take?
It depends on the generation and engine: there are 4 compatible batteries in total, from 13 to 100 Ah and 200 to 850 A of cold cranking. The best sellers for this model are Start-Stop battery Varta A7 12V 70Ah 760A AGM, Car battery Varta H3 12V 100Ah 830A, Start-Stop battery Varta A5 12V 95Ah 850A AGM. With your plate we tell you the exact one in seconds.

### How much does a MERCEDES-BENZ M-Class battery cost?
Between 69.54 € and 169.95 €, VAT included, depending on capacity and technology (AGM, lead-acid). Start-Stop versions (AGM or EFB) sit at the top of the range because they withstand many more cycles.

### How do I know which generation my M-Class is?
By the registration year: M-Class III (2011-2015); M-Class II (2005-2012); M-Class I (1998-2005). If your year falls in the overlap between two generations, tell them apart by body type (hatchback, estate or coupé) or use the plate finder, which settles it with no doubt.

### Can I fit a battery with more amps?
Yes, as long as the dimensions fit the tray and the terminal layout matches. More capacity (Ah) and more cold cranking (A) do not harm the vehicle: the alternator charges it the same and you gain margin in winter. What you must never do is go below the original figures.

### How long does a MERCEDES-BENZ M-Class battery last?
Between 4 and 6 years in normal use. Start-Stop batteries (AGM/EFB) tend to last slightly less in city driving because of the number of starts, but they are designed for that cycling. If the car sits unused for weeks or you notice slow cranking in the cold, get it checked.
