Peugeot 407 Battery Replacement Parts

The Peugeot 407 (2004–2011) typically uses a group 096 or 100 battery depending on engine and specification, but the key figures to match are the physical dimensions (length, width, height), cold cranking amps (CCA), and terminal layout. Because batteries are spec-driven rather than model-driven, a used battery from another vehicle can fit perfectly well provided those figures match. Always confirm the exact spec against your registration with the breaker before buying.

The 407 received a facelift in 2008, but battery fitment is determined by physical size and electrical spec rather than body or styling generation. A battery from a pre-facelift 407 may well be compatible with a post-facelift car if the dimensions, CCA rating, and terminal positions match, but because specifications can vary across model years and engine variants you should confirm the exact part numbers with the breaker against your registration before purchasing.

Engine size and type can influence the CCA rating and sometimes the physical group size of the battery, so a 2.7 HDi diesel may require a higher-spec battery than a 1.6 petrol, for example. That said, batteries are fundamentally spec-driven, and if two cars share the same group size and CCA rating the battery will interchange regardless of which engine it came from. Check the spec figures rather than just the engine code, and confirm with the breaker against your registration.

Trim level does not affect battery fitment on the Peugeot 407; a battery from an SE, Executive, or GT will interchange provided the physical dimensions, CCA rating, and terminal layout match. Higher trims may carry additional electrical loads such as heated seats or upgraded audio, which can mean a higher CCA rating was fitted from the factory, so it is worth confirming the original spec rather than assuming all trims share identical batteries. Expect no cosmetic differences between batteries from different trim levels — they are plain functional units.

The 407 was sold as a saloon, SW estate, and Coupé, and battery fitment across these body styles is determined by spec rather than body style. If the physical size, CCA rating, and terminal positions match, a battery from any of those variants can interchange with your car. Confirm the exact spec with the breaker against your registration to be sure.

When sourcing a used battery from a breaker, the most important checks are that it holds a good charge, has a healthy voltage at rest (typically around 12.6 V when fully charged), and that the physical dimensions and CCA rating match your car's requirement. Used batteries carry an inherent risk as their internal condition is hard to assess, so ask the breaker about its age and whether it has been tested. If in any doubt, a reconditioned or new battery may be a safer investment for a part as critical as this.
