Let us know if you require further assistance.
As per NBN co., when it’s time to replace the battery, you will see a red light appear next to the ‘Replace Battery’ marker on the nbn™ connection box. You’ll also hear an alarm tone, which will beep every 15 minutes to indicate your battery needs replacing. Four beeps per minute means there’s less than half of the battery charge remaining.
If possible, avoid turning your main power on and off as this will significantly reduce your battery life. This also applies if you’re disconnecting the Power Supply unit for a significant amount of time.
