EQUAL CHARGE LED is On; FLOAT CHARGE LED is Off.

*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 has an automatic function to perform the equalize recharge after battery backup operation.
