Peugeot 307 Battery Replacement Parts

The 307 typically takes a group 063 or 096 battery depending on the engine and specification, with common ratings around 45–60Ah and a cold cranking amps figure to match your original — the key numbers to match are the physical dimensions (length, width, height), the Ah rating, and the CCA rating rather than the model year itself. Batteries are spec-driven, so always check the label on your existing battery or your owner's manual for the exact figures before buying. Confirm the spec against your registration with the breaker to make sure you get the right unit.

The Peugeot 307 ran from 2001 to 2008 in the UK, with a facelift arriving in 2005, but for batteries the generation boundary matters far less than the physical size and electrical spec. If the Ah rating, CCA, and dimensions match your original battery, a pre-facelift unit can work in a post-facelift car and vice versa. That said, confirm the exact spec against your registration with the breaker before purchasing.

Trim level does not affect battery fitment on the 307 — an S, XSi, or SW-badged car uses the same battery selection criteria based on engine, Ah rating, and physical dimensions regardless of trim. You may find cosmetic differences such as brackets or terminal covers between cars stripped at a breaker, but these do not affect whether the battery itself fits. Always match the spec rather than the trim name.

Batteries are spec-driven rather than model-driven, so a battery from a 206, 308, or another Peugeot could physically fit your 307 if the dimensions, Ah rating, and CCA all match your original. The 307 shares battery group sizes with several other Peugeot and Citroën models of the same era, making cross-model sourcing quite common at breakers. Confirm the exact spec against your registration with the breaker before buying.

Diesel engines typically demand a higher CCA rating and sometimes a larger Ah capacity than equivalent petrol engines, so an HDi battery and a petrol battery from a 307 are not always interchangeable even if they look the same size. Always check the Ah and CCA figures on your original battery and make sure the replacement matches, regardless of which fuel type it came from. Confirm the full spec against your registration with the breaker to be sure.

The 307 received a facelift in 2005 but the battery specification did not change significantly across that boundary — fitment depends on matching the physical dimensions, Ah rating, and CCA rather than whether the donor car is a pre- or post-facelift example. If the spec matches your original, a facelift battery can work in an earlier car, but given that there can be differences depending on the specific engine variant, you should confirm the exact spec against your registration with the breaker before committing.
