Getting the best from the Long WP4A-BS

An alarm panel beeping at three in the morning usually means its battery is low. Keep spare batteries charged if they are stored for a while. Alarm panels that keep reporting low battery need attention.

How AGM batteries work and how to look after them

Lead plates in AGM batteries are often slightly thinner than in flooded types. Cold starts are easier with AGM thanks to strong current delivery. If the original was AGM, the replacement should be AGM too.
