Based on the batteries we found for your vehicle, our experts help you pick the right one.

📋 What we found

For your Gilera Runner Runner 125 ST we found 11 compatible batteries. This list includes 9 AGM or EFB batteries and 2 auxiliary batteries.

📏 Battery size

The list contains batteries in different sizes or capacities (Ah). In many cases both variants fit, but it's worth checking your compartment dimensions and the Ah of your original battery before buying. Choose the one with the same dimensions as your current battery: a bigger one may not fit the compartment or the hold-down. If several match your size, the higher capacity gives more headroom for cold starts.

⚡ Starter or auxiliary battery

We detected an auxiliary battery among the compatible ones. The auxiliary is NOT your main car battery: it is a smaller secondary battery that powers sensitive electronics. Don't mix them up when buying. Usually what fails is the starter battery (the main one), but the auxiliary can also fail. If your vehicle shows intermittent electronic errors but starts fine, it may be the auxiliary; if cranking is weak, it is usually the starter battery.
