## Lead-acid technology in the FB356

Inside, the FB356 is classic lead-acid: liquid electrolyte and lead plates. It is a robust, well-known technology with a good capacity-to-price ratio, and still the basis of most cars, trucks and traction equipment.

## What to look at before buying the FB356

- If your car has Start-Stop, the FB356 is not the right one: it needs an EFB or an AGM.
- Check the EN amps on your battery: if it says 240 A or less, the FB356 covers your engine.
- With 35 Ah, the FB356 replaces an original battery of that capacity or slightly less.
- Polarity of the FB356: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- Length, width and height of the FB356: 187 × 127 × 220 mm.
