Citroen C4 Battery: Specs, Fitment & Common Faults
On the C4, a genuine, distinct root cause of repeated battery drain is worth checking — a faulty fuse box, not the battery itself.

A Genuine, Real Owner Complaint Worth Knowing About
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 C4 Battery: The Part Everyone Blames First, Not Always Correctly
On the Citroen C4, no single component gets blamed for a no-start more than the battery, and often that blame is justified, making it a sensible first check. But it isn't the whole story every time, so it's worth confirming before spending on a replacement that might not actually fix anything.
Citroen C4 Battery: OEM Part Number
| Type 027 fitment | 242mm length, 175mm width, 190mm height — 52-70Ah depending on technology |
|---|---|
| Type 096 fitment (Start/Stop, AGM) | 278mm length, 175mm width, 190mm height — 70Ah, 760A (EN) |
| Important | Never fit a standard lead-acid battery in place of EFB or AGM on a Start/Stop car — this will cause premature failure and can trigger warning lights. |
Battery specification varies between petrol, mild-hybrid, and fully electric ë-C4 versions — the ë-C4 uses a small 12V auxiliary battery to power electronics separately from its main drive battery, and fitting the wrong type or capacity can cause electrical faults. Mild-hybrid versions also carry a battery management system that some specialists recommend having a new battery registered to, rather than assuming a straightforward swap is sufficient.
Citroen C4 Battery: What It Does
Whenever the Citroen C4's engine isn't turning, the 12V battery is what keeps electrical systems running and handles the next start. That workload is much higher on stop-start versions, given how often the engine switches off and restarts, which is exactly why they call for an AGM or EFB battery rather than a standard type.
