NOTE
In equalize charge mode, the battery is
charged for a programmed period at a
specified voltage (depending on the battery
spec), rather than the float charge, in order
to prevent voltage deviations among battery
cells. This should be done once every six
months if possible.
The G8000 UPS will automatically perform
the equalize recharge after battery backup
operation.
