Why choose the Fulmen FF1251

Getting the best from the Fulmen FF1251
Forestry machines work miles from the nearest workshop. Wipe mud and dust off the battery top to stop small leakage currents. Mixing a fresh battery and a worn one in a 24-volt set is a classic mistake: both fail early.
Care tips for lead-acid batteries
Charging turns lead sulphate back into active material. Flooded batteries offer strong starting current at a fair price. Clean terminal deposits with bicarbonate solution.
Before you order: a quick checklist
- ✓ Note which corner the plus post occupies on your old unit. Here it is positive on the left-hand side, and crossed cables rarely reach.
- ✓ Stored energy reserve: 125Ah. Going much lower than your current battery can leave you short on cold mornings or long stops.
- ✓ For winter starts, 850A should at least match the old battery.
