Managing your Battery Backup

Quick answer

If your connection box is installed with a Power Supply Unit with Battery Backup, you may be required to replace the batteries for your device and our below guide explains how this can be done.

Power Supply Unit with Battery Backup

If your home is connected using Fibre to the Premises (FTTP)/ Home (FTTP/H) technology, your connection box may be powered using a Power Supply Unit that includes a Battery Backup.

In these instances, the Power Supply Unit provides power to your connection box, with the Battery Backup designed to provide your connection box with backup power.

Keep your Backup Battery charged
  • Make sure your Power Supply Unit is always plugged into an electrical outlet and avoid using extension cords or other secondary plug types.
  • The nbn also recommends keeping the power supply plugged in at all times to ensure the battery remains fully charged in case of a power outage.

During a power outage

In the event of a power outage, the battery backup allows a Fibre Phone to be plugged into an active voice port on your connection box and can work for up to 5 hours.

It is important to note however that in the event of a power outage, the backup device won’t support your amaysim internet service and will only support a telephone service. This means you’ll need to have a separate home phone service if you want the option of being able to call during a power outage.

In the event of a power outage, the Power Supply Unit will beep and automatically switch to the backup battery power. Once the battery charge has depleted to 50%, the Power Supply Unit will start beeping four times every minute and then turn off to preserve power. To turn the Power Unit back on after the unit has switched off, follow the below steps;

  1. Press and hold Battery Emergency Use until the unit beeps once and all 4 lights flash
  2. Once this is done, you won't be able to turn the Battery Emergency Use off again and the remaining battery charge should last for approximately 2-3 hours
  3. If the battery runs completely flat, your phone service will not work until the power has been restored

Replacing your battery

If your battery is running low and needs to be replaced, the alarm in your Power Supply Unit will beep and as the battery continues to gets lower, the beeping will become more frequent.

What type of battery will I need?

The battery required for your device must be identical to the current battery in use and you'll need to purchase a 12V/7Ah (or 7.2Ah) AGM sealed lead acid battery (6 Cells) that has a 5+ year design life. Typical battery dimensions are 94 x 151 x 65mm.

These can be purchased from most specialist battery retailers.

Once you’ve purchased the new battery, below are the steps to remove and install your new battery.

Remove the battery
  1. Turn off at the power point and disconnect the power supply from the mains power
  2. Open the front cover of the Power Supply with Battery Backup
  3. Disconnect the red ‘+’ plug from the battery
  4. Push the tabs holding the battery, one above and one below, outward and then lift the battery out
  5. Disconnect the black ‘–’ plug and remove battery
Install the new battery
  1. Reconnect the black ‘–’ plug to the new battery
  2. Push the battery retaining tabs outward and insert the battery into the Power Supply with Battery Backup
  3. Reconnect the red ‘+’ plug to the new battery
  4. Make sure the wires are not being pinched by the battery or front cover
  5. Close the front cover and plug the power supply back into the power point and turn the power on
  6. The new battery will take 24 hours to completely charge. Please retain the old battery as a precaution during this time unless its charge was completely exhausted
  7. Please note, your broadband and/or phone service delivered over the nbn™ network will be unavailable while the battery is being replaced and for up to 10 minutes afterwards
