## 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.

## Frequently asked questions

### Which battery does a Mazda RX-7 take?
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 Dynamic SLI 12V 70Ah 630A, Car battery Varta D47 Dynamic SLI 12V 60Ah 540A. With your plate we tell you the exact one in seconds.

### How much does a Mazda RX-7 battery cost?
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.

### How do I know which generation my RX-7 is?
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.

### Can I fit a higher-capacity battery to my Mazda RX-7?
Yes, as long as the dimensions fit the tray and the terminal layout matches. More Ah and more cold-cranking amps do not harm the Mazda RX-7: the alternator charges it just the same and you gain margin in winter. Never go below the original values.

### How long does a Mazda RX-7 battery last?
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.
