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.
Quick Learn
(Q-Learn)
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 37).

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 time are given
below). During this time, the battery loses energy through self-discharge. After 24 hours,
the battery is discharged to determine the second capacity. The difference between the
second and first capacity is the self-discharge.
