Frequently asked questions

It depends on the generation and engine: there are 2 compatible batteries in total, from 44 to 52 Ah and 440 to 520 A of cold cranking. The best sellers for this model are Car battery Varta B18 12V 44Ah 440A, Car battery Varta C6 12V 52Ah 520A. With your plate we tell you the exact one in seconds.
Between 57.90 € and 57.90 €, VAT included, depending on capacity and technology (lead-acid). Start-Stop versions (AGM or EFB) sit at the top of the range because they withstand many more cycles.
By the registration year: Roadster (2003-2005); Roadster Coupe (2003-2005). 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.
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 Roadster 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.

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.

As a final check, look at the battery currently fitted: the label shows capacity (Ah) and cold cranking amps (A). Always replace with equal or higher figures, never lower, and keep the same dimensions and terminal layout.
