ABBREVIATIONS AND DEFINITIONS
We use a number of abbreviations on the labels to save space. Here are the full
words corresponding to each abbreviation along with common battery charger
terms and their definitions:
ABBREVIATIONS
POL – Polarity. Refers to the correct connection of the Positive and Negative
terminals of the battery to the charger.
DEV – Device. Refers to the charger. Used together with the Fault LED to indicate a
problem with the Device.
BAT – Battery. Refers to the battery. Used together with the Fault LED to indicate a
problem with the Battery.
FLT – Fault. Used to indicate a problem with the battery (BAT) or the device (DEV)
AC – Alternating Current
TEMP – Temperature. Used to indicate that either the Battery or the Device is too
hot.
LO V – Low Voltage. Used to indicate that either the Input Voltage or the Battery
Voltage is too low.
FAIL – Used to indicate that either the battery or the device needs repair or
replacement.
PRG – Program - Button used to initiate the Programming Mode
STG – Stage – Switch used to select between 2-Stage or 3-Stage charging profile
EOC – End Of Charge – Switch used to select Rest or Float at the end of a charge
cycle
SEL – Select – Button used to make choices during front panel programming
CH – Charging
EQ – Equalize
PS – Power Supply
DEFINITIONS
CC – Constant Current. Typically the first phase of a recharge cycle where a
constant current is delivered to the battery until the voltage reaches a specific level.
CV – Constant Voltage. Typically the 2nd or 3rd phases of a recharge cycle where
the battery voltage is maintained at a constant level.
Absorption – The first Constant Voltage stage in a 3 stage charging algorithm,
where the battery is maintained at an elevated voltage for a period of time to ensure
full and equal recharging of all cells.
