Term Explanation
Intrinsically Safe
(I/S)
Batteries with built-in safety protection circuitry. These
batteries are used in volatile environments.
Memory Reversible capacity loss in NiCd and NiMH batteries
caused by an increase in the size of crystals formed
within the battery.
Matrix The set of battery parameters for a specific battery model
stored during the Q-Learn or Learn process and used for
testing batteries of the same model during QuickTest. A
matrix is stored with a C-code.
Recondition A deep discharge below 1.0V/cell with a controlled
current. Reconditioning helps break down large crystals,
which develop as a result of memory, to more desirable
small sizes often restoring the battery to its full capacity.
Applies to NiCd and NiMH only.
Residual Capacity Capacity remaining in the battery when it is inserted in an
analyzer.
Resistance Also called internal resistance. Opposition to current flow
and dissipation of energy in the form of heat.
Self-Discharge Battery capacity lost during storage because of internal
leakage between the positive and negative cell plates.
Smart Battery Battery equipped with circuits that can communicate with
a charger.
State-of-charge The current energy content of a battery.
State-of-health The battery condition that takes into account its capacity,
resistance and self-discharge.
Target Capacity The capacity level (in percentage of manufacturer-stated
battery capacity) that a battery must display to pass a
test of battery capacity. The target capacity is an arbitrary
benchmark set by the user. By default it is set to 80% but
it can be changed.
Trickle Charge Maintenance charge to compensate for battery self-
discharge.
