Troubleshooting NBN Backup Battery Issues

Troubleshooting NBN Backup Battery Issues

Battery backup information for Fibre to the Premises (FTTP)

New MyHomeFone NBN services are installed without battery backup. Your premises, however, may be equipped with battery backup from a previous installation.

If you have a Power Supply with Battery Backup, your NBN Connection Box will continue to be powered for approximately five hours during a power outage.
  1. When approximately 40% of the battery charge is remaining (after about 3 to 3.5 hours), the power supply will automatically turn off to preserve the remaining charge for emergency use.
  2. When you need to use the remaining charge press the emergency reserve button and within a few minutes your services will operate for the remaining approximately 1.5 to 2 hours.
  3. Extremely cold conditions (less than -1 degrees Celsius) may cause the battery to run out more quickly.

If your Power Supply with Battery Backup is showing a red light next to the ‘REPLACE BATTERY’ symbol or you hear an alarm (beeping once every 15 minutes) this either means that you need to replace your battery with a new one or that the battery has been removed. NBN provides the first battery free of charge when the Power Supply with Battery Backup is initially installed. It is your responsibility to purchase subsequent replacement batteries from a reputable supplier. Be aware of inferior batteries with short lifespans.

For more information regarding battery warning lights, tones and how to replace, please refer to the NBN Fibre User Guide available at nbn.com.au/battery

For your own safety, never perform maintenance on your NBN Power Supply with Battery Backup (including disconnecting or replacing the battery) without first reading the detailed instructions in the NBN Fibre User Guide.
