Abbreviations and denitions
We use a number of abbreviations on the labels to save space. Here are the full words corre-
sponding to each abbreviation along with common battery charger terms and their denitions:
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.
SVC – Service. Used to indicate that either the battery or the device needs repair or replace-
ment.
CH – Charging
EQ – Equalize
PS – Power Supply
DEFINITIONS
CC – Constant Current. Typically the rst phase of a recharge cycle where a constant current is
delivered to the battery until the voltage reaches a specic 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 rst 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.
Equalize – A deliberate overcharge at low current to bring a weak cell up to the same charge
level as the good cells in a weak battery. Typically only performed once every few months, and
only if battery exhibits reduced capacity.
