  A short backup time on your Secure Power UPS can occur for several reasons: * 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. * The UPS may be overloaded. Check the connected devices and remove any unnecessary ones. * The battery may be old. Contact Secure Power Ltd for a replacement battery and assistance with assembly.

  If your Secure Power UPS fails to start after pressing the ON key, consider these potential causes: * You may not have pressed the combination keys correctly. Ensure you press both keys simultaneously. * The UPS may have no battery connected, or the battery voltage may be low with too many loads connected. Connect the UPS battery properly. If the battery voltage is low, turn off the UPS, remove some loads, and then try starting it again. * There may be an internal fault. Contact your supplier for servicing.
