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.
