Motorhomes with roof solar may still run short in November when the days are short. Check the mains charger setting each spring. A bank that cannot get through one night with the fridge running needs replacing.

How AGM batteries work and how to look after them
Lead plates in AGM batteries are often slightly thinner than in flooded types. Glass-mat batteries shrug off vibration, which is why bikes and boats use them so often. Recharge an AGM battery promptly after deep use.
