Charging principle of UPS battery in computer room

1. When charging UPS float, please use a charging voltage of 2.275V/cell (set at 20 ℃) for constant voltage charging or a current below 0.002CA for constant current charging. When the temperature is below 0C or above 40C, it is necessary to correct the charging voltage. Starting from 20C, for each degree of change, the voltage of a single cell changes by -3mV.

2. During cyclic charging, the charging voltage is set at 2.40-2.50V/cell (set at 20 ℃) for constant voltage charging. When charging at temperatures below 5C or above 35 ℃, starting from 20 ℃, adjust the charging voltage by -4 mv/cell for each degree of change.
