AGM: how it works

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.
- ✓ Rated 18Ah: check that the charger or alternator in your system can refill a battery of that capacity in reasonable time.
- ✓ For winter starts, 310A should at least match the old battery.
