Using it day to day: practical tips
Three nights at anchor with the fridge running show quickly what a battery bank can really do. Turn off the main isolator when leaving a boat for more than a few days. A bank that cannot get through one night with the fridge running needs replacing.
AGM: how it works
Glass-mat batteries are sealed, with small valves that only open if pressure builds up. Wheelchairs and scooters often use AGM for clean, sealed power. Too much voltage makes the valves vent gas that can never be replaced.
