Source: published VARTA battery-finder fitment data (varta-automotive.com) for the Hyundai Kona (SX2), consulted August 2026. Two case lengths appear across this range – 242 mm and 207 mm – and they are not interchangeable. Measuring the battery you remove is the reliable check. 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.
The Kona SX2 is listed with AGM, not EFB. Match the size and technology of the battery you remove.

Frequently Asked Questions
What battery does a Hyundai Kona need?
An AGM battery, and the size depends on the version. VARTA fitment data for the Kona SX2 lists a type 027 AGM, 242 x 175 x 190 mm, at 60 Ah and 680 A for the 1.0 T-GDi, the 1.0 mild hybrid, the 1.6 T-GDi and one Kona Electric build. The GDi full hybrid and the 218 PS Electric are listed with a smaller type 012 AGM, 207 x 175 x 190 mm, at 50 Ah and 540 A. Note that this is AGM, not the EFB previously shown. Measure the battery you remove before ordering.
Does the Hyundai Kona need an AGM or EFB battery?
AGM. Every Kona SX2 fitment returned by VARTA is an AGM battery and no EFB option appears. Replace AGM with AGM: the charging strategy is built around the AGM charge profile, and an EFB or plain flooded battery will fail early in this car.
How long does a Hyundai Kona 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 Kona 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 →
