How AGM batteries work and how to look after them
Each AGM cell is packed so tightly that the plates barely move, even on a bumpy road. Glass-mat batteries recover well after a deep discharge compared with flooded ones. Old-fashioned chargers without automatic cut-off are a poor match for glass-mat batteries.

If you prefer another make, these fit the same space with the same terminal side.
