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 specically designed for service on cars
and trucks within a voltage controlled electrical system. Most Maintenance
Free Batteries are SLI, otherwise known as Flooded, Regular or Standard
Batteries.
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 ooded 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.
What is an AGM battery?
An AGM battery is an absorbed glass mat 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 bers.
uses a recombination reaction to prevent the escape of hydrogen and •
oxygen gases normally lost in a ooded 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.
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 STATE OF HEALTH?
It means how much battery capacity is left (%) compared with the marked
original battery capacity.
What is STATE OF CHARGE?
It means to what percent the battery is actually charged.
