used in energy systems because of their price, local availability,
and ease of recycling. A properly maintained lead acid cell will last about
ten years. This type of battery will deliver about 1000 full charge-discharge
cycles. The drawbacks of Wet Lead Acid Batteries include the following:

AGM
is a newer
type of sealed battery uses "Absorbed Glass Mats", or AGM between
the plates. This is a very fine fiber Boron-Silicate glass mat. These
type of batteries have all the advantages of gelled, but can take much
more abuse.
AGM
batteries have several advantages over both gelled and wet (flooded)
batteries. Since
all the electrolyte (acid) is contained in the [...]
