Using it day to day: practical tips
A car parked outside through a cold snap asks far more of its battery than one kept in a garage. Lift the battery straight up, never by the terminals. Ordering a battery whose plus post sits on the opposite corner is the most common mistake, and the cables simply will not reach.

What do 41Ah and 370A mean for this battery?
Rated 370A for cold starts and 41Ah in capacity, it will suit engines whose manufacturer specifies equal or lower values. Big diesels in cold climates benefit from extra margin.
Can I connect several of these in series or parallel?
It is rated 12V and 41Ah. Check your equipment's voltage first: a mismatch can damage electronics or simply not work.
Which corner holds the positive post on the Fulmen FC412?
This model is positive on the right-hand side. If your old battery is the mirror image, choose another reference.
How should I charge a battery like this?
Most smart chargers have a mode for lead-acid. Select it before charging; an unsuitable programme can shorten battery life.
Check before ordering
- ✓ Sticking with lead-acid avoids surprises, unless your vehicle maker approves a change.
- ✓ Tape measure time: 207 × 175 × 175 mm is the footprint and height of this case. Leave a little clearance for the clamp and the cable lugs.
- ✓ Plus pole position: positive on the right-hand side. Mixing up orientation is the most common reason a battery of the right size will not connect.
