Frequently asked questions

It depends on the generation and engine: there are 8 compatible batteries in total, from 41 to 70 Ah and 300 to 760 A of cold cranking. The best sellers for this model are Start-Stop battery Varta A7 12V 70Ah 760A AGM, Car battery Varta B18 12V 44Ah 440A, Car battery Varta B32 12V 45Ah 330A. With your plate we tell you the exact one in seconds.
Between 47.60 € and 148.78 €, 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: Mx-5 Rf Targa (2016-2025); Mx-5 IV (2015-2025); Mx-5 III (2005-2014); Mx-5 II (1998-2005); Mx-5 I (1990-1998). 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 MX-5 takes

Easiest of all is the number plate lookup: those few characters tell us the precise variant, the engine and the original battery, so you need not check anything else.

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.

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.

Start-Stop: which battery your MX-5 needs

The later MX-5 generations run Start-Stop, which puts the battery through hundreds of micro-cycles a day. These cars require EFB (basic Start-Stop) or AGM (Start-Stop with regenerative braking): fitting a conventional battery instead cuts service life to a few months and the ECU may disable the function. Rule of thumb: never downgrade from the technology fitted at the factory.
