Why does my MAKELSAN UPS have a short backup time?
- A
  Andrew RussellAug 1, 2025
  If your MAKELSAN UPS has a short backup time, it could be due to several reasons. First, the battery may not be fully charged. To resolve this, keep the UPS connected to mains power for more than 8 hours to recharge the battery. Second, the UPS might be overloaded; check the connected devices and remove any unnecessary ones. Lastly, the battery could be old. If you need to replace the battery, contact an authorized dealer to obtain the correct battery and assembly.

  If your MAKELSAN UPS doesn’t start up after pressing the ON key, consider these possibilities: 1. You may not be pressing the correct combination of keys. Ensure you press the two keys simultaneously. 2. The UPS may not have a battery connected, or the battery voltage might be low with too many loads. Connect the UPS battery properly. If the battery voltage is low, turn off the UPS, remove some loads, and then try starting it again. 3. There may be an internal fault within the UPS. In this case, contact your supplier for servicing.
