## Description

## Where the Fulmen FB620 fits

The Fulmen FB620 is made for petrol and diesel cars without automatic engine stop. If your car has no Start-Stop and had a 62 Ah battery, the FB620 is a direct replacement.
At 62 Ah it is the usual size for compact diesels and mid-size petrol saloons. The FB620 belongs to the Fulmen FULMEN Formula range. [See all Fulmen batteries](https://bateriasonline.es/en/fulmen-batteries)

## Fulmen FB620 vs FA640, FB621 and FB602

The real differences between the FB620 and the closest Fulmen models:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Fulmen FB620 (this one) | 62 Ah | 540 A | 242 × 175 × 190 | right | 13.9 kg |
| Fulmen FA640 | 64 Ah | 640 A | 242 × 175 × 190 | right | 14.9 kg |
| Fulmen FB621 | 62 Ah | 540 A | 242 × 175 × 190 | left | 14.4 kg |
| Fulmen FB602 | 60 Ah | 540 A | 242 × 175 × 175 | right | 12.9 kg |
| Fulmen FA612 | 61 Ah | 600 A | 242 × 175 × 175 | right | 14 kg |
| Fulmen FK620 | 62 Ah | 680 A | 242 × 175 × 190 | right | 17.9 kg |

- Fulmen FA640: 2 Ah more, 100 A more cranking power, the same L2 case.
- The Fulmen FB621 is the same battery with the positive terminal on the other side: choose it if your current battery has the positive terminal on the left.
- Fulmen FB602: 2 Ah less, the same cranking power, a different height (175 mm instead of 190 mm, LB2). It is the option if your battery tray cannot take the 190 mm height of the FB620.
- Fulmen FA612: 1 Ah less, 60 A more cranking power, a different height (175 mm instead of 190 mm, LB2). It is the option if your battery tray cannot take the 190 mm height of the FB620.
- Fulmen FK620: the same capacity, 140 A more cranking power, the same L2 case, AGM technology.

## What to look at before buying the FB620

- Length, width and height of the FB620: 242 × 175 × 190 mm (European case size L2).
- Polarity of the FB620: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- Capacity of the FB620: 62 Ah; the same as your current battery or slightly more is fine.
- Check the EN amps on your battery: if it says 540 A or less, the FB620 covers your engine.
- If your car has Start-Stop, the FB620 is not the right one: it needs an EFB or an AGM.

## Inside the FB620: lead-acid technology

Inside, the FB620 is classic lead-acid: liquid electrolyte and lead plates. If the FB620 is left discharged for weeks it sulphates: a maintenance charger prevents this.
