Fitting and everyday care

Long-weekend sailors often run the fridge and nav lights all night. Set the mains charger, the solar regulator and any B2B charger to the AGM profile. Years of nightly cycling eventually take their toll on any leisure battery.

AGM: how it works

Many glass-mat designs tolerate sideways mounting, as long as the maker says so. Wheelchairs and scooters often use AGM for clean, sealed power. Too much voltage makes the valves vent gas that can never be replaced.

Five checks for a perfect fit

• ✓ A case of 330 × 173 × 237 mm must sit flat with the clamp closed.
• ✓ Rated 110Ah: check that the charger or alternator in your system can refill a battery of that capacity in reasonable time.
• ✓ Cranking power on cold mornings: 1100A. Big engines in harsh winters call for a generous figure.
