over. Once successful, test other batteries with the same capacity, if possible, to ensure
that the SoH readings are within an acceptable range.
To create the most effective matrix, repeat the above steps with more batteries. It is
recommended to run the Learn program on at least three batteries: one with a capacity
above 90%; one with a 70-80% capacity and finally one at 70% capacity. The batteries
can be run through the Learn program in any order.
The battery matrix will be erased if anything in the C-Code is changed except for the target
capacity and the actual program (i.e Auto, Charge, Prime, QuickTest or any of the other
programs).
Q-Learn (Quick Learn)
Function: Q-Learn creates and stores a matrix in a C-Code for use by QuickTest. The Q-
Learn program is only run once on a battery. For more accurate results, use the Learn
program instead.
Sequence: This program assumes that the battery has 100% capacity. If a battery has
lower capacity, it will not make a correct matrix. The program consists of a charge and a
discharge and the OhmTest. The data obtained from the program profiles the battery’s
SoH (called a matrix) and automatically stores it with the battery C-Code.
Results: Detailed display shows the battery’s average cell voltage; analyzer charge or
discharge current (in mA); OhmTest results; battery temperature and duration of service.
If Q-Learn is successful, the C-Code will display a T in the upper right-hand corner to
indicate that a QuickTest matrix has been created.
Duration: Approximately 5 minutes for all batteries with a SoC (state of charge) level
between 20% and 90% of battery capacity. Batteries with a SoC level lower than 20% or
greater than 90% require additional time to bring their SoC to between 20% and 90%.
For most batteries, this takes an additional 5 minutes but in some cases, especially with
high-capacity batteries, it may take longer.
