Inverter/UPS Battery Not Charging
A Inverter/UPS with the "Battery Not Charging" fault usually shows it through the charge indicator never reaches full, backup time keeps shrinking day by day, and the battery feels warm even when idle. This is typically traced back to a battery that has reached end of life and no longer holds charge, a faulty charging circuit, and loose or corroded battery terminals. A technician resolves it by load-testing the battery, checking the charging circuit output, and cleaning or replacing corroded terminals.
