What to do if my Huawei UPS2000-A-6KTTL-S battery discharge time is too short?
- C
  Connie BurtonAug 17, 2025
  If the battery discharge time is much less than the standard time, it could be that the batteries are not fully charged. In this case, charge the batteries for more than 8 hours when the mains is normal. Alternatively, the battery performance may have deteriorated. Test the discharge time again, and if the issue persists, contact local Huawei technical support to replace the batteries.

  If the UPS does not start after you press the power button, it could be that the button was not pressed long enough. Press the button for more than 5 seconds until you hear a beep. Another possible cause is an overload. Disconnect all loads and restart the UPS.
