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 ins
ide 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 0OF 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.
