Why the year matters for the battery of your Bmw Z4 Roadster

  • Manufacturers change battery spec mid-production of a model.
  • An identical engine can fit AGM Start-Stop in one version and conventional in an earlier one.
  • Amp-hours (Ah) and cold-cranking amps (CCA) also vary between years of manufacture.
  • Fitting the wrong battery can cause electronic faults, dashboard warnings and abnormal alternator load — on cars with BMS, registering it via OBD after the swap is required.

Enter the year and you will see the manufacturer-recommended battery alongside compatible alternatives from market-leading brands (Varta, Tudor y Exide). Express 24h delivery.

Frequently asked questions

The Bmw Z4 Roadster 2.5 Si requires a battery with the correct capacity (Ah) and Cold Cranking Amps (CCA) for this engine. Browse the compatible battery list below.
The exact Ah rating for the Bmw Z4 Roadster 2.5 Si depends on the vehicle's original electrical consumers. Use our finder for a precise recommendation.
To find the exact battery you need, you need to know the make, model, and engine. If your car has a Start-Stop system (the engine shuts off at traffic lights), you need an AGM or EFB battery. An AGM battery can only be replaced with another AGM battery. However, an EFB battery can be replaced with either another EFB or an AGM battery, as the latter is superior.
The standard battery is the conventional type. The EFB battery withstands start/stop cycles better. The AGM battery is the most durable and is mandatory in cars with Start-Stop and regenerative braking. Never replace an AGM battery with an EFB or standard battery.
