Hyundai i20 Battery

Not automatically. The i20 sold in South Africa as PB, then GB, then the current BC3, and the PB and GB are different cars underneath despite the shared badge, so a part listed simply as "i20" is not automatically the right one — the generation code decides it. Send us the generation code off your VIN plate and we will confirm it either way before anything is dispatched.

We work backwards from the VIN: generation first, then engine family, then whether the car is pre- or post-facelift within that generation. On the i20 specifically, the PB and GB are different cars underneath despite the shared badge, so a part listed simply as "i20" is not automatically the right one — the generation code decides it.

Costs depend on your model, engine and whether you need standard, EFB or AGM. A 1.4 CRDi i20 runs a smaller low-cost battery, while a stop-start Creta needs an AGM plus a battery-management (BMS) reset. We can quote against your VIN — ask for a free quote.

Slow cranking, stop-start dropping out, the 'battery charge fault' message, flickering dash lights and repeated BCM (body control module) glitches are the classics. On i20s and Cretas you'll often see infotainment resets first. Get it load-tested before it strands you — most SA workshops test free.

Usually parasitic drain from a failing BCM (body control module), a stuck relay or a dash-light fault on i20/Accent models. Short-trip driving around town rarely lets the alternator fully charge either. A proper parasitic-draw test will confirm whether it's the battery or a drain.

This warning is usually the BCM (body control module) detecting low voltage under load — not always a dead battery. Common causes include a tired battery, a slipping auxiliary belt, a weak alternator or a failing BCM or battery sensor on i20/Accent. Scan first, replace parts second.

Four to six years is typical in SA conditions. Coastal humidity and Highveld heat both shorten life and stop-start cycling ages AGM batteries faster than older Hyundais' flooded units. Annual load-testing from year three onwards is the sensible approach.

We source Hyundai batteries nationally through our supplier network. You get the correct Ah rating, CCA and AGM spec for stop-start equipped i20, Tucson and Creta models, plus battery-management (BMS) reset support where needed. Send us your VIN for a same-day quote.
