Frequently asked questions

It depends on the generation and engine: there are 7 compatible batteries in total, from 44 to 63 Ah and 420 to 680 A of cold cranking. The best sellers for this model are Car battery Varta D24 12V 60Ah 540A, Car battery Varta D15 12V 63Ah 610A, Start-Stop battery Varta N60 12V 60Ah 640A EFB. With your plate we tell you the exact one in seconds.
Between 44.19 € and 106.70 €, VAT included, depending on capacity and technology (lead-acid, EFB, AGM). Start-Stop versions (AGM or EFB) sit at the top of the range because they withstand many more cycles.
By the registration year: Forfour Hatchback (2014-2025); Forfour (2004-2006). 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 SMART Forfour 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.

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 Forfour needs

If your Forfour has Start-Stop, the battery works far harder than usual — hundreds of restarts a day rather than a handful. That calls for EFB or AGM, depending on whether the system is basic or includes regenerative braking. A conventional battery there lasts months and can make the car switch Start-Stop off.
