## Quick description

The Fulmen FB456 is a car battery with 12 V, 45 Ah and 330 A cold cranking current, case size B24 (237 × 127 × 227 mm), with the positive terminal on the right. Need the positive terminal on the left? The same battery is the Fulmen FB455.

## Description

## Who the Fulmen FB456 is for

The Fulmen FB456 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 45 Ah battery, the FB456 is a direct replacement.
At 45 Ah it is a small size: the usual choice for petrol superminis and city cars with little equipment. The FB456 belongs to the Fulmen FULMEN Formula range. [The full range of Fulmen batteries](https://bateriasonline.es/en/fulmen-batteries)

## Lead-acid technology in the FB456

The FB456 is a conventional lead-acid battery, with plates immersed in liquid electrolyte. In cars without energy management, the FB456 needs no special registration: just connect it.

## Before ordering the FB456, check this

- If your car has Start-Stop, the FB456 is not the right one: it needs an EFB or an AGM.
- Check the EN amps on your battery: if it says 330 A or less, the FB456 covers your engine.
- Capacity of the FB456: 45 Ah; the same as your current battery or slightly more is fine.
- The FB456 has the positive terminal on the right: compare it with your current battery.
- The FB456 needs 237 × 127 × 227 mm of space (European case size B24): measure it with the hold-down clamp in place.

## Frequently asked questions about the Fulmen FB456
