## Frequently asked questions

### Which battery measures 186x82x171 mm?
The 3 models on this page fit a 186x82x171 mm tray exactly (length × width × height), with prices from 144.96 € VAT included.

### Can I fit a slightly smaller battery?
Yes, if it is properly clamped with the original fixing: a few millimetres less in length or height is usually fine. What never fits is a battery LARGER than the tray, and watch terminal height so it does not touch the bonnet.

### Which capacities exist in 186x82x171 mm?
In this size you will find batteries of 18, 19, 22 Ah. For equal size, more Ah and more CCA usually means a better battery for your car.

### Do the dimensions include terminals and the hold-down ledge?
Yes. We publish each battery's total maximum volume: hold-down ledge, lid edges and terminal height where they protrude. If your tray takes these figures, the battery fits safely.

### Can I change technology while keeping this size?
Yes, always equal or upwards: from conventional to EFB or AGM is fine — they share the standard case — but never downwards in Start-Stop cars. Each model's technology is shown on its card and you can filter by it above.
