Citroen C3 Battery: Specs, Fitment & Common Faults
On the C3, a genuine, distinct root cause of repeated battery drain is worth checking — a faulty fuse box, not the battery itself.

Citroen C3 Battery: OEM Part Number
| Standard Start/Stop fitment | Type 027, EFB, 60Ah, 560A (EN) |
|---|---|
| Case dimensions | Typically 242 x 175 x 190mm |
| Important | Never fit a standard lead-acid battery in place of EFB on a Start/Stop car — this will cause premature failure and can trigger warning lights. Some Stellantis Start/Stop vehicles also need the battery management system reset with a diagnostic tool after fitting. |
A Genuine, Real Owner Complaint Worth Knowing About — Citroen C3 Battery
If your stop-start has stopped working reliably despite a relatively new battery, this is worth knowing directly: one documented owner's blunt assessment, after extensive troubleshooting with their dealer, was that the AGM battery fitted to these cars is "not fit for purpose" — needing a full charge on a proper smart AGM charger roughly every two to three weeks just to keep stop-start functioning during a pattern of shorter, everyday trips, despite the battery otherwise starting the car normally. If you're finding yourself charging the battery repeatedly just to restore stop-start rather than experiencing a genuine one-off fault, you're likely not alone, and it's worth raising this directly with Citroen rather than assuming your specific battery is simply defective.
A genuinely useful benchmark worth knowing: a healthy car at rest should draw well under 50 milliamps from the battery. If a multimeter test shows anywhere close to double or triple that figure, that's a genuine parasitic drain worth chasing down circuit by circuit rather than simply replacing the battery again.
Citroen C3 Battery: The Part Everyone Blames First, Not Always Correctly
On the Citroen C3, more non-starts get pinned on the battery than on any other single component, and that assumption is correct often enough to justify checking it first. It's not always the real cause, though, so it's worth confirming before spending money on a replacement that doesn't fix the problem.
Citroen C3 Battery: What It Does
On the Citroen C3, every engine start and every moment the electrical systems run without the engine turning draws on the 12V battery. Stop-start puts far more demand on that battery than older designs, given how often the engine cycles off and on — hence the need for an AGM or EFB battery instead of a standard type.
