If you receive an email from TPG indicating your NBN backup battery may have an issue then you need to decide if you wish to replace the battery. Replacing the backup battery is optional and is done at your own cost. The guide below will help you decide if you want to replace the battery, what type of battery is needed and where to get it and walk you through the process of actually replacing the battery
Will the NBN battery backup work at my premises?
To make calls during a power outage for up to five hours, you need to make sure you have all the following:
Power Supply with Battery Backup
A phone service connected on the NBN connection box’s UNI-V port
A standard corded phone that doesn’t need to be plugged into a power point
If you have a cordless phone or a phone that connects to a router, then these devices will not work during a power outage and you will not be able to make calls
What type of battery do I purchase if I choose to replace the backup battery and where do I get it?
