batteries can only be discharged to 50%, whereas the lead acid battery can be discharged to 80%. battery is considerably more expensive.Ģ. The deep cycle A.G.M. batteries can stand very low temperatures without freezing.ĥ. These batteries are also very resistant to vibration, due to their sandwich construction. This allows them to be used safely inside a motorhome.Ĥ. A.G.M. batteries do not give off any gas (hydrogen) when being charged, so there is less concern about ventilation when charging them. battery never needs any water, and is considered to be maintenance free.ģ. A.G.M. This means if you turn the battery upside down, the electrolyte will not spill out of an A.G.M. battery is seen as a rectangular shape case, the plates themselves can be changed into any shape, including flat or even cupped.Īs manufacturing processes have become cheaper, these Deep Cycle Batteries (Leisure Batteries) are now used in Motorhomes. These glass fibre mats do not absorb the electrolyte, but simply hold the electrolyte preventing it from spilling when the battery is tipped over. battery will not freely flood the plates, as the glass mats will prevent this happening. battery to work like a lead acid battery, although the electrolyte in the A.G.M.

It was given this name because these batteries are made up of mats, in which the glass fibres are woven to increase the surface area. is the abbreviation of absorption glass mat.

battery was originally designed to be warm weather and vibration resistant.Ī.G.M. This was an alternative to the then very expensive Ni – Cad batteries, which were used in naval helicopters and fighter jets. During the 1980s the aircraft industry developed the A.G.M.
