Frequently asked questions
- It depends on the engine. Mercedes-Benz SLK owners mostly buy Varta E44 Dynamic SLI 77Ah (85.40 €), Varta D15 Dynamic SLI 63Ah (81.80 €) and Tudor TB740 Technica 74Ah (61.95 €) from us. The table shows the recommended battery for each engine with its price (VAT included) and a link to its page; with your number plate or VIN we tell you the exact one in seconds.
- Between 64.95 € and 160.45 €, 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: Slk III (2011-2025); Slk II (2004-2011); Slk I (1996-2004). 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.
- Four to six years in normal use. Start-Stop batteries (AGM/EFB) tend to last a little less in city driving because of the number of restarts, but they are built for that cycling. If the car sits for weeks or cranks slowly in the cold, have it tested.
- Typical signs: sluggish cranking in the cold, headlights dimming on start-up, a battery warning on the dash or electronics resetting. A workshop can check resting voltage (below 12.4 V means discharged) and cranking capacity in a minute.
