Why Your NBN Battery Matters

Your NBN connection relies on a battery backup unit (BBU) that keeps your internet and voice services running during power outages. Without a working battery:

You cannot make emergency (000) calls during a blackout
Home businesses lose connectivity and productivity
Remote workers lose access to essential services
Elderly or vulnerable residents may lose safety-critical communications
Smart home devices and alarms may fail

  • Flashing or red indicator lights on the battery unit
  • NBN or phone stops working during power outages
  • Battery is older than 3–5 years (recommended replacement interval)
  • NBN provider has sent you a replacement reminder
