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
