5.10Battery Recharging

The illustration below shows a graphical representation of the UPS battery recharge process after a full discharge.

The recharge process usually consists of three steps. During the first step, the charging current is maintained at approximately 4.0 amperes for the 15/25/30/33kVA and approximately 11.5 amperes for the 50 kVA. This current is the maximum value that can be used to charge the batteries (for minimal recharge time) while assuring safety and long battery life. In the second step, constant-voltage control starts and current gradually decreases as the batteries charge to their normal fully charged state. In the third step, a slight "trickle" current continues to flow into the batteries to keep them fully charged and "floating" at the normal DC Voltage level. A full recharge usually requires approximately 24-72 hours (90% recharge in 10 hours) after a complete discharge.

The following chart shows the rated maximum and minimum battery voltages, and the charge current for each of the sizes while the unit is maintained in a 75°F (24° C) ambient.
