The replacement and repair of UPS Batteries should be done according to the actual situation. These are some situations that may indicate the need to replace or repair UPS batteries:
Schedule regular maintenance: The manufacturer of the UPS should provide a schedule for routine maintenance. It may be necessary to perform tasks like testing the battery regularly, checking the battery wiring and cleaning terminals. The battery will need to either be repaired or replaced if the maintenance plan identifies a problem.
Battery test results that are abnormal: Whether you use automatic testing, load testing or any other method of battery testing, if your test results reveal problems like insufficient capacity, too little duration, abnormal voltage, or an increased internal resistance, it may be necessary to replace or repair the battery.
Reminder about the fault indicator light: Many UPS systems have fault indicator lights which will sound an alert when the battery experiences a fault. The fault light or sound may indicate that the battery is in need of repair or replacement.
Performance degradation: If your UPS system is not able to provide continuous power as expected during an outage or power outage, and UPS overloads or failures are frequent, this may indicate that the battery has degraded performance. The battery should be replaced or repaired.
Battery life: Batteries have a lifespan that is determined by the manufacturer of your UPS. Even if a battery is in good condition, it might need to be replaced if its life expectancy has been exceeded.
To ensure safe and correct operation, you should always seek professional help when replacing or repairing batteries.
