## Description

## Where the Fulmen FL754 fits

The Fulmen FL754 is designed for automatic engine stop and regenerative braking. In a Start-Stop car, the FL754 keeps the radio, climate control and lights running with the engine off without losing capacity.
At 75 Ah it sits in the range of compact and mid-size diesels, SUVs and MPVs. The FL754 belongs to the Fulmen FULMEN EFB range. [See all Fulmen batteries](https://bateriasonline.es/en/fulmen-batteries)

## Before ordering the FL754, check this

- Length, width and height of the FL754: 260 × 173 × 222 mm (European case size D26).
- Polarity of the FL754: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- Your current battery should say about 75 Ah; a little more is also fine.
- Check the EN amps on your battery: if it says 750 A or less, the FL754 covers your engine.
- The FL754 is an EFB: it suits cars that had an EFB or a conventional battery. If yours had an AGM, fit another AGM.

## EFB technology in the FL754

Inside, the FL754 uses EFB technology, a reinforced version of the flooded battery. The FL754 works with normal chargers that have a lead-acid or EFB mode.
