Source: published VARTA battery-finder fitment data (varta-automotive.com) for the SEAT Ibiza Mk5 (KJ), consulted August 2026. SEAT fits two different case lengths to this car: type 027 is 242 mm long and type 012 is 207 mm long. They are not interchangeable, so this is one of the cars where measuring the old battery really matters. 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.
Two case lengths are fitted to this car. Measure the battery you remove before ordering.

Frequently Asked Questions
What battery does a SEAT Ibiza need?
Either a type 027 or a type 012, and which one you have depends on the build rather than the engine. VARTA fitment data for the Ibiza Mk5 (KJ) flags both as recommended on most engines: a type 027 EFB of 60 Ah and 640 A measuring 242 x 175 x 190 mm, or a type 012 conventional battery of 52 Ah and 470 A measuring 207 x 175 x 190 mm. The two cases differ by 35 mm in length and are not interchangeable, so measure the battery you remove before ordering.
Does the SEAT Ibiza need an AGM or EFB battery?
EFB where the car is fitted with the type 027 battery and has start-stop. VARTA also lists a conventional flooded type 012 against most Ibiza engines, which covers builds without start-stop, and an AGM option on the 1.0 TSI 110 PS. The rule that keeps you right is to match the technology printed on the battery you take out, and never to downgrade a start-stop car to a plain flooded battery.
How long does a SEAT Ibiza 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 SEAT Ibiza 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 →
