Issue:
BMS AP9921X-AP9922; alarms “Battery Low Chemistry Voltage”
Product line:
Battery Management System (BMS) AP9921X & AP9922
Environment:
All models, all serial numbers
Cause:
The voltage of a battery is below the threshold for the battery type.
Resolution:
Identify the listed batteries immediately so that system backup time is not reduced. Check for exterior causes of this alarm, such as a loose connection or corrosion on a battery post. If the battery has no external problems, perform a follow-up reading with a battery tester. If a specific battery causes repeated alarms (especially if the voltage continues to decrease), the battery is failing. Replace the battery.
