Battery Settings
Battery parameter settings impact battery maintenance, battery lifespan, and UPS discharge
time. When you set battery parameters, note the following:

Retain default settings for Chg. cur. limiting coef. and Cell float voltage. Only
professional maintenance personnel are allowed to change the settings.
When you set parameters, ensure the following: Chg. cur. limiting coef. > Transfer-to-
equalized charging cur. coef.
Single batt. float chg. voltage deviation alarm thres. and Single batt. dis. voltage
deviation alarm thres. are used to check whether the batteries in each battery string have
the same charge voltage and discharge voltage. When a value exceeds the specified range,
an alarm is generated. The calculation formula is (Charge/Discharge voltage – Average
voltage)/Average voltage x 100%. The charge/discharge voltage and average voltage are
obtained from the BMU. If the BMU is not configured, these two parameters do not need
to be set.
