  mark57Aug 15, 2025
  Several factors can cause a short battery discharge time in your Allsai UPS. It could be due to the battery being undercharged; in this case, keep the UPS battery recharging for more than 3 hours. Another reason might be the UPS being overloaded; check the load level and disconnect any non-critical equipment. Lastly, the battery may be aging and losing capacity, consider replacing it with a new one and contact the supplier to get the new batteries and spare parts.

  If your Allsai UPS fails to start, make sure you press the power key for more than 2 seconds. Also, check if the input connection is ready or if the UPS internal battery is disconnected; connect the input well, and if the battery voltage is too low, disconnect the input and start the UPS with no-load. If the problem persists, it may be due to an internal system fault.
