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.

OEM Part Number: Type 027

Accuracy note: Most C3s take a 242 mm type 027. Non-stop-start petrols use a standard 027 (54–63Ah); the 1.2 PureTech stop-start needs a 027 EFB; the Mk2 1.6 e-HDi was specified with a 278 mm type 096 AGM. Check the three-digit type code, Ah and CCA printed on the battery you are removing before ordering — this model was built in more than one size. Stop-start cars must have an EFB or AGM battery, never a standard one.
C3 Mk2 (2009–2016) and Mk3 (2016 on), petrol without stop-startType 027 standard (54–63Ah / 530–610A); some 1.0/1.2 use the smaller 063. Aftermarket: Yuasa YBX3027 (62Ah / 550A); Varta D15 / C22; Bosch S4 005
C3 Mk3 (2016 on), 1.2 PureTech stop-startType 027 EFB (60Ah / 640A). Aftermarket: Yuasa YBX7027 EFB (65Ah / 600A) or YBX9027 AGM (60Ah / 640A); Varta N60 EFB / A8 AGM; Bosch S4E 051 / S5A 050
C3 Mk2 (2010–2016), 1.6 e-HDi stop-startType 096 AGM (70Ah / 760A) — AGM only, not EFB. Aftermarket: Yuasa YBX9096 AGM (70Ah / 760A); Varta A7; Bosch S5A 080
C3 Mk3, 1.5 / 1.6 BlueHDi stop-startType 096 EFB (70Ah / 760A). Aftermarket: Yuasa YBX7096 EFB (75Ah / 700A) or YBX9096 AGM (70Ah / 760A); Varta N70 EFB / A7 AGM; Bosch S4E 081 / S5A 080

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 genuine, distinct root cause worth checking if the battery keeps draining overnight: a faulty fuse box has been documented as the actual cause of repeated flat batteries on more than one occasion, with lights, wipers, and the fan randomly activating and draining the battery even with the car locked and untouched. A replacement fuse box, sourced independently for under £100, resolved this completely in documented cases — worth considering if you've already replaced the battery more than once without a lasting fix.

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.

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.

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.
