Peugeot 208 Battery: Specs, Fitment & Common Faults

Why the 208's engine range genuinely needs more than "a battery" — from stop-start EFB requirements to the e-208's separate 12V auxiliary battery, plus why registration matters after replacement.

Peugeot 208 Battery: OEM Part Number

Accuracy note: confirmed across both first and second-generation 208s with Start/Stop, which covers the large majority of the range — always confirm against your existing battery's label or your VIN, since diesel and higher-demand variants can differ.

Standard Start/Stop fitment	Type 027 (L2 format), EFB, 60Ah, 640A (EN), 242 x 175 x 190mm, positive terminal on the right
Some diesel/higher-demand variants	Larger Type 096 (L3 format), EFB or AGM, 70Ah, 760A (EN), 278 x 175 x 190mm
Important	Never fit a standard lead-acid battery in place of EFB or AGM — this will disable Start/Stop entirely, and the replacement needs registering (coding) to the car's battery management system regardless of technology.

Peugeot 208 Battery: The Part Everyone Blames First, Not Always Correctly

A Peugeot 208 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 type genuinely matters here, not just size. The 208's engine range spans basic petrol and diesel through to mild-hybrid and fully electric versions, and each has different demands on the 12V battery — confirm your exact trim against your VIN before ordering.

Why the 208 Genuinely Needs More Than Just "A Battery" — Peugeot 208 Battery

Standard, non-stop-start versions of the 208 can run a conventional flooded battery, but any 208 with stop-start — the large majority of petrol and diesel versions sold in recent years — needs at minimum an EFB (Enhanced Flooded Battery), which is built to withstand far more frequent charge cycling than a standard unit without premature failure. Fitting a standard battery to a stop-start 208 is a genuine mistake: it isn't built for the repeated deep cycling stop-start demands, and it will fail considerably sooner than its rated life. The fully electric e-208 uses a separate small 12V battery purely for auxiliary systems — entirely distinct from the large high-voltage drive battery — and this 12V unit is what actually fails and needs replacing if the car won't power on, not the main battery pack.

Modern 208s Often Need the Battery "Registered" After Replacement

On 208s fitted with a Battery Management System (increasingly the norm across the range), simply bolting in a new battery isn't the end of the job — the car's electronics need to be told a new battery is fitted, typically via a diagnostic tool, so the charging system manages it correctly from day one. Skipping this step can leave you with a battery that never quite charges right, or a stop-start system that quietly disables itself without explanation. If you're not doing the replacement yourself, confirm whoever fits it also completes this registration step.
