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.

14.3.6 Changing to Float Charge from Protection Charge (If applicable)  
Table 19 shows the manual procedure to change from protection charge to float charge.  
This operation applies to batteries which needs protection charge when over temperature.  
(1) The battery is normally being charged at float charge mode.  
(2) To prevent the battery thermal runaway, this mode will automatically be changed to protection  
charge when a "BATT FAULT1" (Battery over temperature) warning occurs.  
(3) In protection charge mode, the battery is automatically charged at a voltage about 5% lower than  
float charge.  
(4) If the "BATT FAULT1" warning message goes away and a programmed duration is elapsed (about  
24 hours), this mode will automatically be changed back to float charge. So, it is not usually required  
to change the recharge mode manually back to the float charge.
