Cadex C7400ER - Selfdch (Self-Discharge Test)

Program Does this Is used for this
Boost Applies a 100mA trickle
charge for 3 minutes.
Reactivating batteries that are not
recognized by the Cadex analyzer
because of low voltage or an open
protection circuit.
Q-Learn
(QuickLearn)
This program assumes that a
battery has 100% capacity. It
profiles the battery and saves
the data to the QuickTest™
matrix in the C-code.
Rapidly establishing an accurate
QuickTest™ matrix based on the
SoH of a new battery that is known
to be good.
Learn Applies a charge-discharge-
charge cycle to determine
battery capacity, profiles the
battery, saves the data to the
QuickTest™ matrix in the C-
code.
Establishing or modifying
QuickTest™ matrix using a
spectrum of batteries with various
SoH.
Increasing QuickTest™ accuracy
(confidence grade) for a given
battery type.
QuickTest™ Tests battery SoH by
comparing battery data to
data from other batteries of
the same model stored in the
QuickTest™ matrix in the C-
code.
Gives an estimate of battery SoH
to help sort batteries.
A matrix is required to run this
program (see Q-Learn Procedure,
page 43).

SelfDCH (Self-Discharge Test)
Function: Identifies the self-discharge or the amount of charge a battery loses if it
is left alone for a period of time. The standard time is 24 hours.
Sequence: The battery is charged and discharged to obtain its first capacity. The
battery is then charged and left for a 24-hour rest period (instructions to change this
