Using it day to day: practical tips
A caravan that spends the winter parked on the drive often comes back in spring with a flat battery. Fit a fuse close to the battery on the main positive lead. Draining a lead bank flat every night shortens its life drastically.
The AGM technology explained
Gas produced during charging recombines inside an AGM battery, so it loses almost no water. Many modern cars with brake energy recovery were designed around AGM from the start. Charge an AGM battery in a cool, ventilated place.
