GLOSSARY
What is a GEL battery?
A gel battery is a lead-acid electric storage battery that:
■ is sealed using special pressure valves and should never be opened.
■ is completely maintenance-free.
■ uses thixotropic gelled electrolyte.
■ uses a recombination reaction to prevent the escape of hydrogen and oxygen
gases normally lost in a flooded lead-acid battery (particularly in deep cycle
applications).
■ is non-spillable, and therefore can be operated in virtually any position.
However, upside-down installation is not recommend-ed.
■ Connections must be retorqued and the batteries should be cleaned
periodically.
What is an AGM battery?
An AGM battery is a lead-acid electric storage battery that:
■ is sealed using special pressure valves and should never be opened.
■ is completely maintenance-free.*
■ has all of its electrolyte absorbed in separators consisting of a sponge-like mass
of matted glass fibers.
■ uses a recombination reaction to prevent the escape of hydrogen and oxygen
gases normally lost in a flooded lead-acid battery (particularly in deep cycle
applications).
■ is non-spillable, and therefore can be operated in virtually any position.
However, upside-down installation is not recommended.
■ Connections must be retorqued and the batteries should be cleaned
periodically.
