CHAPTER 5: BASIC OPERATIONS
5.7.4.3
EQUALIZING THE GPU BATTERIES
An “equalizing charge” is a controlled overcharge that brings up low cells and/or removes sulfur
from the plates in the GPU Batteries. This process is essential for obtaining full battery
performance. JBT LEKTRO, Inc. recommends performing an equalizing charge every month.
To do this:
1. Wait until the GPU Batteries are fully charged and the GPU Battery Charger has completed
the finishing cycles.
2. Disconnect the GPU Battery Charger from the incoming AC power supply.
3. Reconnect the GPU Battery Charger to the incoming AC power supply. This force-restarts
the charger, which will run for at least its 45-minute auto-timed base period up to
approximately two hours, depending on electrolyte and ambient temperatures.
Note
JBT LEKTRO, Inc. recommends repeating this sequence no more than two (2) times.
The supplied GPU Battery Charger has a higher designed finishing rate than manual
chargers, and too many restarts may damage the GPU Batteries because of excessive
heat.
Note
Some replacement chargers may have a different “equalizing” feature. Refer to the
manufacturer's instructions in this case.
