Tired of that constant low battery beep from your NBN unit? Call Battery Australia for a fast, reliable, and affordable NBN battery replacement service, available 7 days a week across Melbourne.
Our quick replacement process takes just minutes and ensures your phone and internet services stay up and running during power outages — giving you complete peace of mind.
Starting from just $129, we’ll have a technician at your door within 40 minutes. Don’t wait — contact Melbourne Batteries today for prompt, professional service!
The backup battery in your NBN unit is designed to keep your phone and internet running for up to 5 hours during a power outage. If the battery is flat or faulty, these services won’t work — which can be critical in an emergency.
When it’s time to replace the battery, a ‘Replace Battery’ light will appear on your NBN box, accompanied by a single beep every 15 minutes. If you hear four beeps every minute, it means the battery has less than 50% charge remaining and should be replaced soon.
Stay safe and connected — don’t ignore the warning signs.
Our technician will replace your NBN backup battery in approximately 10 minutes. Please note that your phone and internet services will be temporarily unavailable during this time, as the unit needs to be powered off for safety.
Once the new battery is installed, the ‘Replace Battery’ light will switch off, and the beeping will stop, restoring your system to full functionality.
