NBN Battery Relacement

NBN battery replacement Melbourne

Have you got NBN Fibre to the Premises (FTTP)?

Next to your NBN fibre NTD (Network Termination Device), there will most likely be a battery backup.

The battery backup is installed in the event of a blackout to give you the advantage of still using your home phone and internet.

Once the battery has lost its charge a red light will appear followed by an annoying “beep” every 15 minutes.

This means the battery is out of charge and must be replaced.

Phoneworks is the No.1 NBN Battery replacement company in Melbourne.

⚠️ WARNING: Installing the wrong battery or attempting a DIY replacement can damage NBN equipment and void compliance. Always use a licensed cabler for battery replacements.

How the NBN Battery UPS works

Although blackouts are uncommon they do still occur during a storm or electrical failure. It’s important to understand what your battery back up does and how to use it.

Once the main power has been interrupted the NBN battery back up will automatically switch on and run the NBN NTD for up to 2 hours
Once the battery has depleted 50% of its charge it will “Beep” telling you it’s about to turn off to sustain a charge for an emergency
to Utilise the rest of the battery press and hold the “emergency button” for up to 5 seconds until you hear a “beep”. This means the emergency back up will run your NBN equipment for up to another 2 hours

Note: This only powers the NBN NTD and not your devices i.e Router, Phones and computers. A separate Uninterrupted Power Supply (UPS) should be installed to power your devices.

What to Do If Your NBN Battery Goes Flat

If your NBN backup battery is flat or showing warning lights, you have two options:

1. Replace the Battery

If you rely on a landline for emergency calls, the battery must be replaced. A licensed technician can install the correct battery and restore backup power.

2. Remove the Battery Backup Unit

In most cases, the battery unit is no longer necessary. Phoneworks can remove it and install a 240V power supply, keeping your NBN equipment powered from the mains.

⚠️ Note: During a power outage, your NBN unit will stay on—but your modem/router won’t unless it’s connected to its own backup power.

Phoneworks technicians carry genuine NBN parts and can quickly replace your battery or convert your setup for a more reliable, modern solution.

Getting Your NBN Backup Battery Replaced

NBN-supplied backup batteries typically last up to 24 months. After this period, the battery is no longer covered under warranty, and it becomes the customer’s responsibility to replace it.

When you book Phoneworks, our licensed technicians will:

✅ Inspect your existing NBN equipment

✅ Supply and install the correct replacement battery

✅ Test for proper operation and continuity

✅ Issue a Certificate of Compliance for your records

Installing the wrong battery — or attempting a DIY replacement — can risk damage to NBN equipment. That’s why battery replacement should always be handled by a licensed Cabler.

What our clients are saying

Called peter to connect my NBN, these guys always amaze me they are great to talk to on the phone and always on time. Nothing is too much trouble for them Nick even fixed my Foxtel for me, something he didn’t have to do but that’s the type of guys they are. Thankyou Peter and Nick for another great job you did for me

We always had issues with our internet speed that other technicians were unable to fix. Your technician was proficient and carried out his work meticulously. Our speeds have increased from 3,500 kbps to 21,000 kbps on one ADSL service. The other back up service increased from 3,150 kbps to 19,000 kbps. Needless to say, the problems were solved and we have had no internet issues since.

It is a rare thing for me to want to take the time to comment on service, but I must say that your recent work done at our Cheltenham office was really excellent. The friendly can do attitude of your staff is what sets you apart from the rest. Well done and thanks again!

Mindsystems Pty Ltd, Cheltenham, Vic

Our internet was not acceptable, so i rang the lovely lady at Phoneworks. Juanita was very understanding and assured one of the boys would come out later that day.

Before i knew it a lovely guy by the name of Nick arrived at my house and replaced my wiring which he said was not suitable for NBN. Now I have a fast, reliable connection.
Thank you so much, Juanita & Nick 🙂

Joanne Sommers

What can I say – your phone technician was brilliant! Clearly a highly qualified professional. I will be recommending him and Phoneworks whenever possible, especially to other newcomers to my building.

Just a great service! Your phone technician certainly “went the extra mile” to please and make sure things were done just right.

Your Phoneworks technician came out on Saturday and was fantastic. Telstra came out onsite this afternoon to do their part and we are up and running!
