Peugeot 3008 Battery: Specs, Fitment & Common Faults

Before assuming a fault, check the genuine conditions that legitimately prevent stop-start from working — plus a real, expensive case showing even a new module and battery don't always fully fix it.

OEM Part Number: 540-610A

Genuinely important to know: on earlier Mk1 3008s, a battery change must be registered with the control unit — this isn't optional cosmetic advice, it's specified directly on genuine Bosch fitment listings for this exact model.

Mk1 (2009-2016), standard fitment	242-278mm case, 60-63Ah, 540-610A (EN), lead-acid, requires control unit registration after replacement
Mk2 (2016 onwards), 2.0 BlueHDi, Start/Stop	EFB technology, 70Ah, 760A (EN)
Hybrid4/Hybrid variants	12V auxiliary battery, genuinely separate from the high-voltage hybrid drive battery

Before Assuming a Fault: Stop-Start Has Genuine Conditions for When It Won't Engage — Peugeot 3008 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: one owner had a new Battery Protection Module fitted (costing around £400) along with a genuine replacement battery, and stop-start still only activated infrequently even after a long motorway run. Separately, a Peugeot dealer's own service manager reportedly experienced the identical fault on his own car despite twice-daily 45-minute motorway journeys, suggesting these later 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 — an expensive module and battery replacement doesn't guarantee a permanent fix.

It's also worth knowing that a genuine battery issue can cascade into seemingly unrelated faults on Stellantis vehicles — electric parking brake warnings, wipers stopping working, and economy mode activating together are a documented pattern after a battery is disconnected and reconnected, generally resolving once the car's systems are properly reset by a specialist rather than simply refitting the battery and expecting everything to recover on its own.

Peugeot 3008 Battery: The Part Everyone Blames First, Not Always Correctly

A Peugeot 3008 that won't start gets blamed on the battery more often than any other component, and it's right often enough to make that assumption a reasonable first check. But it's not always the actual cause, which is worth knowing before spending money on a replacement that doesn't fix anything.

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 3008 Battery: What It Does

The Peugeot 3008's 12V battery provides the power needed to start the engine and runs electrical systems when the engine isn't turning. On cars with stop-start technology, the battery works much harder than on older designs, since the engine switches off and restarts far more frequently — which is exactly why these cars need a specific AGM or EFB battery type rather than a standard unit.
