## How to know which battery your MERCEDES-BENZ Cla takes

The real shortcut is your registration number. It settles generation, engine and factory battery in seconds — exactly where most people get it wrong when buying.

You can also work it out yourself: find the registration date in the vehicle documents and locate it in the table. If the year overlaps two generations, the body style — hatch, estate or coupé — tells them apart.

Before ordering, inspect your existing battery: its label lists the Ah and the starting amps. The replacement must match or beat both — never fall short — and share the same size and positive terminal side.

## Start-Stop: which battery your Cla needs

Start-Stop on the modern Cla 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 Cla take?
It depends on the generation and engine: there are 4 compatible batteries in total, from 13 to 80 Ah and 200 to 800 A of cold cranking. The best sellers for this model are Start-Stop battery Varta A7 12V 70Ah 760A AGM, Start-Stop battery Varta A6 12V 80Ah 800A AGM, Start-Stop battery Varta A8 12V 60Ah 680A AGM. With your plate we tell you the exact one in seconds.

### How much does a MERCEDES-BENZ Cla battery cost?
Between 69.54 € and 146.65 €, VAT included, depending on capacity and technology (AGM). 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 Cla is?
By the registration year: Cla (2019-2025); Cla Shooting Brake II (2019-2025); Cla Shooting Brake I (2015-2019); Cla Coupe (2013-2019). 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 Cla 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.
