Commonly Used Terms
Term Explanation
Milliampere Hour
(mAh)
Battery capacity or rating. A battery that provides a current of
1000 milliamperes for 1 hour is rated at 1000mAh (or 1Ah).
Battery
A combination of cells.
Capacity
The amount of energy that a fully charged battery is capable
of holding.
Configuration Code
(C-Code)
Battery parameters stored in Battery Adapters that tell the
Cadex analyzer how to service a specific battery type (see
Chapter 6 - C-Codes (Configuration Codes) page 41).
Cells
Individual items within the battery.
Cycle
One charge and discharge sequence, even if the battery is
only partially charged or discharged.
C-rate
A “C” number is a value that is used to calculate charge and
discharge times.
A battery rated at 1000mAh provides 1000mA for one hour if
discharged at 1C. A discharge of 1C draws a current equal to
the rated capacity. The same battery discharged at 0.5C
would provide 500mA for two hours.
Battery cycle
A charge followed by a discharge (or a discharge followed by
a charge). Even when batteries are partially charged and
discharged, a cycle is considered to have occurred.
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.
