Frequently asked questions

It depends on the generation and engine: there are 2 compatible batteries in total, from 60 to 70 Ah and 540 to 630 A of cold cranking. The best sellers for this model are Car battery Varta E23 12V 70Ah 630A, Car battery Varta D47 12V 60Ah 540A. With your plate we tell you the exact one in seconds.
Between 69.95 € and 83.80 €, 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: Rx-7 III (1992-2002); Rx-7 II (1990-1991); Rx-7 II Convertible (1990-1992). 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 Mazda RX-7 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.

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.

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.
