Expected Result
When the UPS is backed up,
discharge a battery to the
undervoltage alarm threshold
to refresh the capacity of the
battery.
1. When battery strings are
powered off, check the
reliability of each
connection point from
positive terminals to
negative terminals. All
points are connected
reliably.
2. Use a torque wrench to
check the tightening
torque for each battery
screw. The torque meets
the requirements of the
battery manufacturer.
After checking that the
battery screws meet the
requirements, mark the
screws for later check.
