Care tips for AGM batteries
Oxygen formed at one plate travels through the mat and recombines at the other. Low internal resistance lets AGM deliver strong bursts of current on demand. Store AGM batteries charged and disconnected.

A motorhome parked on the drive slowly loses charge to its alarm and tracker. Check the charge splitter or relay after fitting new batteries. Leaving a caravan battery flat all winter often ruins it.
