What it means that the FB621 is lead-acid
Inside, the FB621 is classic lead-acid: liquid electrolyte and lead plates. It is a robust, well-known technology with a good capacity-to-price ratio, and still the basis of most cars, trucks and traction equipment.
Check this before ordering the Fulmen FB621
- If your car has Start-Stop, the FB621 is not the right one: it needs an EFB or an AGM.
- The FB621 delivers 540 A cold cranking (EN standard); do not go below what your original battery states.
- Capacity of the FB621: 62 Ah; the same as your current battery or slightly more is fine.
- With the terminals facing you, the positive terminal of the FB621 is on the left.
- The FB621 needs 242 × 175 × 190 mm of space (European case size L2): measure it with the hold-down clamp in place.
