Lead-acid technology in the FB712
Inside, the FB712 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 FB712
- If your car has Start-Stop, the FB712 is not the right one: it needs an EFB or an AGM.
- The FB712 delivers 670 A cold cranking (EN standard); do not go below what your original battery states.
- Your current battery should say about 71 Ah; a little more is also fine.
- Polarity of the FB712: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- The FB712 needs 278 × 175 × 175 mm of space (European case size LB3): measure it with the hold-down clamp in place.
