GLOSSARY
Memory
Term is commonly used to refer to Voltage Depression. Memory
is a dendrite deposit on the cell plates that causes an increase of
the internal resistance of the cell. If not corrected by periodic
cycling, memory can destroy the battery prematurely.

Negative Slope
Also known as Negative Delta V; the voltage drop that occurs
when a NiCd battery has reached full charge. This voltage drop is
applied to terminate the fast charge. Full-charge status is main-
tained with trickle charge.
Nominal Battery
Based on number of cells multiplied by cell voltage (1.25 V per
Voltage
cell for NiCd, 2V per cell for lead Acid).

On a battery with mismatched cells, each cell reaches full charge
at different times, counteracting
the negative slope. The result is
a flat voltage curve rather than a negative slope. The Plateau
Timer safely terminates the fast charge in the absence of the
negative slope.
If terminated by the Plateau timer Code 12 is shown, indicating
that the battery has mismatched cells.
A program that prepares new or stored batteries for field use by
repeatedly cycling until the optimum performance
is reached.
Random Access Memory. Used by computers for fast access,
temporary data storage.
Recondition.
A method proprietary to CADEX battery analyzers which reverses
damage caused by "memory". Method consists of controlled
deep- discharge applied below 1 volt per cell.
The amount of charge left in the battery after field use ...
Standard interface to serial printer and/or computer.
A battery adapter with a memory chip built into it for storing the
battery parameters.
