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.

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.
What is a SLI battery?
These initials stand for Starting, Lighting and Ignition, which are the three basic
functions which a battery has to perform on all normal vehicles. Batteries given
this description will have been specifically designed for service on cars and trucks
within a voltage controlled electrical system. Those SLI batteries which are
intended for heavy haulage vehicles fitted with large diesel motors may often be
