Cheap Peugeot 308 Battery

The 308 is spec-driven when it comes to batteries — what matters is the physical size group (typically referred to by EN/DIN code), the cold cranking amps (CCA), and the amp-hour (Ah) rating, not the trim or body style. Check your existing battery's label or your handbook for the exact spec, as different engines across the 308 range can call for different ratings. Always confirm the spec with the breaker against your registration to make sure you get the right unit.

This question spans a generation boundary — the first-generation 308 ran from 2007 to 2013, and the second-generation 308 launched in 2013 with a facelift in 2017, so a 2013 car could be either generation depending on build date. Batteries are spec-driven rather than model-driven, so what matters is that the physical size, Ah rating, and CCA match — not which generation the donor car came from. Confirm the exact spec with the breaker against both registrations to make sure the figures align before buying.

Trim level does not affect which battery a 308 requires — Access, Active, Allure, and GT are the same car underneath in terms of battery fitment. What can vary is the engine fitted, which may influence the required CCA and Ah rating, so match on spec rather than trim name. You may find a used battery sourced from any trim level is perfectly suitable as long as the numbers on the label match your requirement.

Batteries are spec-driven, so a unit from the first-generation 308 could physically fit a second-generation car if the size group, Ah, and CCA ratings are identical — the generation boundary matters far less here than it would for, say, a body panel. That said, whether a specific used battery from a Mk1 donor actually matches your Mk2 car's requirement is something you should confirm with the breaker against your registration, as engine variants across the two generations may call for different specs.

It can matter, yes — diesel engines typically demand a higher CCA rating than equivalent petrols because they require more power to turn over a higher-compression engine, so a battery from a diesel donor may carry a different spec to one from a petrol car. The key is to match the Ah and CCA figures on the battery label to what your car requires, regardless of what engine the donor vehicle had. Share your registration with the breaker so they can confirm the used battery's spec suits your exact engine.

The 2017 facelift updated the 308's styling and equipment but did not fundamentally change battery fitment requirements, which are driven by spec — physical size, Ah, and CCA — rather than facelift status. A battery from a pre-facelift second-gen 308 could well be compatible with a post-facelift car if the figures match, but this is not guaranteed. Confirm the exact spec with the breaker against your registration before agreeing a purchase.
