Figure 3.53 Battery Setting Screen 2
1. Battery Study: When battery aging occurs, this function is to calibrate backup time estimation. It’s a self-learning
function for battery. Currently, this function is not available.
a. Enable: When enabled, UPS will enter battery test mode one time. It will calibrate backup time estimation
by calibrating battery virtual capacity according to a complete charging and discharging process.
b. Disable: When disabled, the backup time will not be updated during the charging and discharging process.
2. Battery Initial:
a. Yes: When selected, the battery virtual capacity will be initialized to 100%. Because battery study is a self-
learning function, after the battery is used for a long time, the virtual capacity of the battery will be
continuously updated based on each full charging process. After replacing the new battery, the virtual
capacity of the battery needs to be initialized.
b. No: When selected, the virtual capacity of the battery will not be initialized.
3. BATT Cali Value: Calibrate backup time.
4. BATT TEMP Compensation: Compensate charging voltage according to battery temperature.
