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 posi-
tion. However, upside-down installation is not recommended.
• 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 posi-
tion. However, upside-down installation is not recommended.
• Connections must be retorqued and the batteries should be cleaned
periodically.
What is a VRLA battery?
Valve Regulated Lead Acid Battery – This type of battery is sealed
Maintenance Free with a "Bunce" Valve or Valves in the top of them
that opens when a preset pressure is realized inside the battery and
let's the excess gas pressure out. Then the valve resets itself.
