Terminal side (the L or R in the code) changes between variants and facelifts — fitting the wrong hand means the cables will not reach. Check the battery in your car, or send us a photo of the label and we will confirm the fitment.

How to read your battery code

A JIS code such as 55B24LS breaks down as: 55 the performance index (roughly the capacity class — the true rating here is about 45 Ah), B the case class which fixes width and height, 24 the length in centimetres, L the terminal side (positive on the left, viewed from the terminal face), and S for slim posts. European cars instead use DIN/EN codes such as DIN55, where the number is the capacity in amp-hours, or AGM case codes such as H7-AGM for stop-start cars.
