Source: published VARTA battery-finder fitment data (varta-automotive.com) for the Kia Niro II (SG2), consulted August 2026. The label “L1 (DIN)” previously shown on this page is a case-size family, not a fitment – the OE data distinguishes the three powertrains by type number. 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 three Niro powertrains take three different batteries. Match the size and technology of the battery you remove.

Frequently Asked Questions
What battery does a Kia Niro need?
It depends which Niro you have, and the three powertrains do not share a battery. VARTA fitment data for the Niro II (SG2) lists a type 012 EFB, 207 x 175 x 190 mm, at 50 Ah and 550 A for the 1.6 GDi full hybrid; a type 027 EFB, 242 x 175 x 190 mm, at 60 Ah and 640 A for the plug-in hybrid; and a conventional type 027 of 60 Ah and 540 A for the EV, where it is the 12 V system battery rather than the traction pack. Measure the battery you remove before ordering.
Does the Kia Niro need an AGM or EFB battery?
EFB on the full hybrid and the plug-in hybrid, with AGM available in both sizes as an upgrade. The EV is listed with a conventional battery as its recommendation. Match the technology printed on the battery you take out. The 12 V battery in a hybrid or EV still runs the control electronics, so do not fit something cheaper than what came out.
How long does a Kia Niro 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 Kia Niro 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 →
