Frequently asked questions

It depends on the generation and engine: there are 9 compatible batteries in total, from 60 to 100 Ah and 540 to 850 A of cold cranking. The best sellers for this model are Car battery Varta E11 12V 74Ah 680A, Car battery Varta E44 12V 77Ah 780A, Start-Stop battery Varta A7 12V 70Ah 760A AGM. With your plate we tell you the exact one in seconds.
Between 64.95 € and 179.99 €, VAT included, depending on capacity and technology (lead-acid, AGM). Start-Stop versions (AGM or EFB) sit at the top of the range because they withstand many more cycles.
By the registration year: Clk II (2002-2010); Clk Convertible II (2002-2010); Clk Convertible I (1998-2002); Clk I (1997-2003). 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.
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.
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.

How to know which battery your Mercedes-Benz CLK takes

Easiest of all is the number plate lookup: those few characters tell us the precise variant, the engine and the original battery, so you need not check anything else.

Another route is the vehicle paperwork: the registration date places you in one of the generations listed. In the overlap years, body style is the detail that separates them.

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 CLK needs

Start-Stop on the modern CLK 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.
