Source: published VARTA battery-finder fitment data (varta-automotive.com) for the Hyundai i20 III (BC3/BI3, 2020 onward), consulted August 2026. Note the mild-hybrid models take the shorter 207 mm type 012 case, not the 242 mm type 027. Where more than one battery is listed, the manufacturer fits different sizes across builds — measure the battery you remove, or confirm by registration, before ordering.

Frequently Asked Questions
What battery does a Hyundai i20 need?
It depends on the engine. OE fitment data for the i20 III (BC3) lists the 1.0 T-GDi 48V mild hybrid with a type 012 battery – 52Ah / 470A in the 207 x 175 x 190 mm case, with 012 EFB and 012 AGM also listed – and the 1.2 MPi with a type 027 (60Ah / 540A, 242 x 175 x 190 mm). The mild-hybrid case is 35 mm shorter than a type 027, so measure before ordering.
Does the Hyundai i20 need an AGM or EFB battery?
Yes — EFB is required because the Hyundai i20 has start-stop technology. EFB for ISG (idle stop & go) system
How long does a Hyundai i20 battery last?
Typically 4–6 years depending on driving patterns. Short urban journeys and cold winters reduce battery life. Start-stop systems are harder on batteries, so quality EFB batteries are essential.
Can I replace the Hyundai i20 battery myself?
Yes for most models — it’s usually located in the engine bay. However, start-stop vehicles may need the battery management system reset with a diagnostic tool after fitting.
How we check fitment for this guide
We cross-reference fitment figures against manufacturer specifications and OE-supplier catalogue data where available, and matched to the standard codes that actually govern fit — battery type/group sizes, wiper lengths and fitting types, bulb fitment codes, tyre size markings, and oil specifications. We work by make, model, year, engine, and build date, because a single model can take different parts across its life. Where the right part depends on your exact vehicle, we tell you to confirm by registration or VIN. More on our method →
