Before Assuming a Fault: Stop-Start Has Genuine Conditions for When It Won't Engage — Peugeot 2008 Battery

A genuinely common source of "my stop-start doesn't work" confusion is worth ruling out first: Peugeot's own manual lists specific conditions where the system deliberately won't activate, including being on a steep slope, the driver's door being open, the seatbelt unfastened, not yet having reached 6mph since the last start, the electric parking brake being applied, or the system needing the engine running to maintain cabin temperature or demist the windscreen. If your stop-start seems inconsistent, it's worth checking whether one of these genuinely explains it before assuming a fault.

A genuinely important, real account worth knowing about if stop-start still won't work reliably after ruling out the above: a Peugeot dealer's own service manager reportedly experienced the same intermittent stop-start fault on his own car despite twice-daily 45-minute motorway journeys, suggesting these systems are genuinely sensitive to battery charge state in a way that even consistent long-distance driving doesn't always resolve. This is worth knowing simply to set realistic expectations before paying for diagnostics or a replacement battery.

Peugeot 2008 Battery: The Part Everyone Blames First, Not Always Correctly

Ask anyone why their Peugeot 2008 won't start and "the battery" is usually the first guess, and it's frequently correct, which makes it a reasonable starting point. It's not always right, though, so it's worth ruling out other causes before spending on a replacement that changes nothing.

Before you buy: battery size, capacity and type (standard vs AGM/EFB for stop-start systems) vary by trim and engine. Always confirm against your VIN before ordering.

Peugeot 2008 Battery: What It Does

On the Peugeot 2008, powering the engine start and running electrics while the engine's stopped both fall to the 12V battery. Stop-start technology puts significantly more strain on it than older designs, thanks to how frequently the engine cycles — explaining why a specific AGM or EFB battery is needed rather than a standard unit.
