Which Battery Does a Subaru WRX Need?
The right battery for your WRX depends on whether it has stop-start, and on its engine. Petrol models take a standard calcium battery; stop-start models need an EFB. Fitting a standard battery to a stop-start car causes early failure.
| Variant | System | Battery Type | Typical Group |
|---|---|---|---|
| Petrol — base | Standard charging | Standard | 55D23 / NS70 |
| Petrol — Stop-Start | Idle-stop system | EFB | Q85 EFB (D23) |
| High-spec / accessories | Added electrical load | Heavy-Duty | 65D26L |
Indicative types only — we confirm the exact group size for your VIN/build at the time of service.

WRX Stop-Start Models Need the Right Battery + Coding
Many newer Subaru WRXs use an EFB battery to support idle-stop. A standard battery fitted to a stop-start car fails early. Stop-start models also need the battery registered to the ECU. We confirm the right spec for your exact WRX and code it properly — every time.
