GLOSSARY
WHAT IS A VRLA BATTERY?
WHAT IS A SLI BATTERY?
WHAT IS STATE OF HEALTH?
WHAT IS STATE OF CHARGE?
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.
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. Those SLI batteries which are intended for heavy
haulage vehicles tted 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.
It means how much battery capacity is left (%) comparing with the marked original
battery capacity.
It means how many percent of the battery is actually charged.
WHAT IS CCA (COLD CRANKING AMPS)?
WHAT IS AMPERE-HOUR?
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 reects the ability of
the battery to deliver engine starting currents under winter conditions.
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.
