    What to do if the Huawei UPS battery discharge time is too short?
    • S
      Susan CameronAug 14, 2025
      If the Huawei UPS battery discharge time is significantly less than expected, it could be due to a couple of reasons. First, the batteries may not be fully charged; in this case, charge them for at least 8 hours with normal mains power, and then test the discharge time again. Second, the battery performance may have deteriorated, requiring you to contact local Huawei technical support to replace the batteries.
