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.
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 called COMMERCIAL
batteries. They have to be much more powerful and more
robust than batteries intended for cars.
What is STATE OF HEALTH?
It means how much battery capacity is left (%) comparing
with the marked original battery capacity.
What is STATE OF CHARGE?
It means how many percent of the battery is actually
charged.
What is CCA (COLD CRANKING AMPS)?
The current in amperes which a new fully charged battery
can deliver for 30 seconds continuously without the terminal
voltage falling below 1.2volts per cell, after it has been cooled
to 0 O F and held at that temperature. This rating reflects the
ability of the battery to deliver engine starting currents under
winter conditions.
What is AMPERE-HOUR?
The unit of measurement of electrical capacity. A current of
one ampere for one hour implies the delivery or receipt of
one ampere-hour of electricity. Current multiplied by time in
hours equals ampere-hours.
