Function: Determines total battery life by the number of cycles. Checks whether
the battery meets the standard life for its chemistry. This is an accelerated aging
test and the battery cannot be renewed after this test.
Sequence: The battery is charged and discharged continuously until the battery
fails (i.e. battery capacity falls below target capacity) or the maximum number of
cycles has been reached.
Results: Global display shows failure-warning message. Detailed display shows
percentage capacity for the first cycle and the last three cycles run. It also displays:
average battery or cell voltage; analyzer charge or discharge current (shown in
mA); OhmTest results; battery temperature and duration of service.
An additional display screen (press from detailed display) shows cycle number,
percentage of battery capacity achieved and OhmTest results for the first and last
cycles run.
Look for the number of cycles (a cycle is a charge followed by a discharge).
Batteries should provide the number of cycles as specified by the manufacturer.
Typically, with a target capacity of 80%, NiCd batteries should provide about 1500
cycles, NiMH 500 cycles, Li-ion & Li-Ph 500 cycles, and SLA 300 cycles.
Duration: Approximately one month or more depending on the chemistry.
To edit the Life Cycle Test settings
The program uses the target capacity set in the C-code to determine when the
program should end (see Target Capacity, page 49). To terminate the program
after a certain number of cycles, do the following:
1. From the global display, press MENU.
2. Press or to scroll to PROGRAM SETTINGS, then press ENTER.
3. Press or to scroll to LIFECYCLE COUNTER, then press ENTER.
4. Press or or use the number pad to select the number of cycles.
5. Press ENTER. Press or scroll to YES to accept changes and press
ENTER.
