A Powerware 9120 2000 is an uninterruptible power supply (UPS) device that provides power backup to connected devices in case of power outages or other power issues. If the UPS is shutting down at 50% charge and showing low power alarm, there could be several possible causes:
The battery is failing: The UPS is designed to shut down when the battery charge reaches a certain level to prevent damage to the battery. If the battery is failing, it may not be holding a charge and may need to be replaced.
The battery is not compatible: Make sure that the battery you are using is compatible with the Powerware 9120 2000 UPS. Using an incompatible battery can cause the UPS to shut down or display error messages.
The battery cable is loose: Check the battery cable connections to ensure that they are tight and secure. A loose battery cable can cause the UPS to shut down or display error messages.
The UPS is overheating: Check the UPS for any signs of overheating, such as a hot feeling on the top of the unit or a burning smell. An overheating UPS can cause the UPS to shut down or display error messages.
The UPS firmware is outdated or corrupted: Check to ensure that the UPS firmware is up to date and not corrupted. Outdated or corrupted firmware can cause the UPS to shut down or display error messages.
If none of these solutions solve the problem, it's recommended to contact the manufacturer or a professional technician for further assistance. They will have the knowledge and expertise to troubleshoot and diagnose the issue with your Powerware 9120 2000 UPS.
Did your UPS display "Battery disconnected" or did it display "Battery Failure"? If it was "Battery Failure", for some reason the Powerware 9120 will take almost 18 hours after plugging in to power after battery replacement to correct the Battery Failure indication. Charger has to charge up the batteries, followed by an automatic battery test by the UPS. If the indication was "Battery Disconnected", you will need to check the internal fuses to see if they are blown. If the UPS keeps blowing fuses, it will require a board repair.
1st, the 9120 is a 700, 1000, 1500, 2000, 3000, 5000 or 6000 Va
if it is a 6000 Va that voltage sounds ok, and the ups as no problem, each battery will be around 12,75 Volts, it will be higher and the charging circle ends.
sometimes the battery tester is not enough to check the battery. battery also prone to tear and wear.because of charging ang discharging. replace the battery
I replaced the batteries but i still get
