Practical advice for trucks and farm machinery
Snow ploughs start in the small hours on the coldest nights of the year. Recharge a battery that has stood unused for a month before relying on it. Ignoring overnight cab loads when choosing a battery leads to flat starts on long-haul trips.
What lead-acid means for you
Serviceable batteries have caps for checking the acid. Lead-acid suits trucks and farm machinery where simplicity and value count. Avoid deep discharges, which encourage sulphation.
Before you order: a quick checklist
- ✓ A case of 353 × 175 × 190 mm must sit flat with the clamp closed.
- ✓ Same box, opposite posts? Many sizes exist in both layouts. This one is positive on the right-hand side.
- ✓ Stored energy reserve: 100Ah. Going much lower than your current battery can leave you short on cold mornings or long stops.
Frequently asked questions
Can a battery be stored before use?
Yes, but all batteries self-discharge slowly. Check the voltage every few months and recharge if needed.
Will the Fulmen FJ1000 fit my battery space?
Length, width and height are 353 × 175 × 190 mm, and the weight is 21.8 kg. Compare with the space available, including clearance above the posts.
How do capacity and cranking amps compare with my old battery?
Rated 850A for cold starts and 100Ah in capacity, it will suit engines whose manufacturer specifies equal or lower values. Big diesels in cold climates benefit from extra margin.
What voltage and amp-hours does this model have?
Nominal voltage is 12V and capacity 100Ah. Wiring two in series doubles the voltage, while parallel wiring doubles the capacity.
