## Quick description

## Description

## The Fulmen FL1000 at a glance

The Fulmen FL1000 is a battery for cars with Start-Stop: it withstands many more starting and partial-discharge cycles than a conventional battery and powers the electronics every time the engine stops at the lights. In a Start-Stop car, the FL1000 keeps the radio, climate control and lights running with the engine off without losing capacity.
At 100 Ah it moves into large diesels, SUVs, vans and cars with heavy electrical equipment. The FL1000 belongs to the Fulmen FULMEN EFB range. [See all Fulmen batteries](https://bateriasonline.es/en/fulmen-batteries)

|---|---|---|---|---|
| Exide EL1000 | EFB | 100 Ah | 900 A | 353 × 175 × 190 |

## Check this before ordering the Fulmen FL1000

- Measure the space: the FL1000 takes up 353 × 175 × 190 mm (European case size L5).
- The FL1000 has the positive terminal on the right: compare it with your current battery.
- Your current battery should say about 100 Ah; a little more is also fine.
- Check the EN amps on your battery: if it says 900 A or less, the FL1000 covers your engine.
- The FL1000 is an EFB: it suits cars that had an EFB or a conventional battery. If yours had an AGM, fit another AGM.

## What it means that the FL1000 is EFB

The FL1000 is an EFB: flooded lead-acid with reinforced plates and separators for Start-Stop. Compared with a conventional battery, the FL1000 withstands far more starts and partial discharges.

## Frequently asked questions about the Fulmen FL1000

### Fulmen FL1000 or FK960?

Compared with the FL1000, the Fulmen FK960 has 4 Ah less, 50 A less cranking power and AGM technology. The FL1000 cranks harder; the FK960 is only a good option if your original battery says 850 A or less. Both measure 353 × 175 × 190 mm, so they fit the same tray.

### Can the Fulmen FL1000 be used in a car with Start-Stop?

Yes, the FL1000 is an EFB: it suits Start-Stop without brake energy recovery, or cars that already had an EFB. If your car left the factory with an AGM, fit another AGM.

### How much does the Fulmen FL1000 weigh?

The FL1000 weighs 25.5 kg. For reference, the Fulmen FK960 (96 Ah) weighs 26.1 kg.

### Which battery is equivalent to the Fulmen FL1000?

In EFB or AGM, with its dimensions and polarity: Exide EL1000, Tudor TL1000 and Varta N95. A conventional battery does not replace the FL1000.

### What case size is the Fulmen FL1000?

Case size L5: 353 × 175 × 190 mm. The FL1000 fits any standard L5 battery tray such as the Exide EL1000.

### Which side is the positive terminal on the Fulmen FL1000?

The FL1000 has the positive terminal on the right, looking at the battery from its long side with the terminals closest to you.

### Can I fit the Fulmen FL1000 if my car came with an AGM battery?

Only if the FL1000 is AGM. A car that leaves the factory with AGM must always run AGM; an EFB in its place will not last and may trigger dashboard warnings.
