Over-discharge protection voltage 2.5V ± 0.08V

These are the main parameters measured by the monitor:

Total battery voltage
Half battery voltage
Current (Integrated Hall-effect sensor)
Temperature (Submersible probe)
Electrolyte level (Submersible probe)
Ah charged/discharged per cycle
Ah charged/discharged in total
State of Charge (SOC)
Number of cycles

In addition to battery-backup support, the monitor equiment performs the important function of monitoring the remaining capacity of the lithium battery and providing a warning before the battery reaches end-of-life. Because the open-circuit voltage of a lithium backup battery remains relatively constant over the majority of its life, accurate battery monitoring requires loaded-battery voltage measurement.
