## Description

## Who the Fulmen FC652 is for

The Fulmen FC652 is a starter battery for cars without Start-Stop: it delivers the current the starter motor needs and then powers lights, control units and audio with the engine off. If your car has no Start-Stop and had a 65 Ah battery, the FC652 is a direct replacement.
At 65 Ah it is the usual size for compact diesels and mid-size petrol saloons. The FC652 belongs to the Fulmen FULMEN Standard range. [More Fulmen batteries](https://bateriasonline.es/en/fulmen-batteries)

## What it means that the FC652 is lead-acid

The FC652 is a conventional lead-acid battery, with plates immersed in liquid electrolyte. Avoid leaving them discharged, as they sulphate, and charge them with a charger that cuts off or switches to maintenance when finished.

## What to look at before buying the FC652

- If your car has Start-Stop, the FC652 is not the right one: it needs an EFB or an AGM.
- The FC652 delivers 540 A cold cranking (EN standard); do not go below what your original battery states.
- Capacity of the FC652: 65 Ah; the same as your current battery or slightly more is fine.
- Polarity of the FC652: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- Measure the space: the FC652 takes up 278 × 175 × 175 mm (European case size LB3).
