Tesla Powerwall 2 recall in Australia: what to do

Tesla has an open Australian recall on the Powerwall 2. It covers units sold between 1 November 2020 and 23 August 2025, and within that window it affects only some units. Tesla identifies affected batteries individually and notifies the owner through the Tesla app. If yours is one of them, the replacement is free and you book it through whoever installed it.

We install and service Tesla Powerwall around Canberra and the surrounding NSW towns, with more than 900 batteries on homes. Powerwall 2 owners ring us about this recall most weeks. Every fact below comes from the ACCC record.

What the recall covers

The record is PRA 2025/20611 on the ACCC's product safety register, published 16 September 2025 and last amended 12 August 2026. It names the Powerwall 2 battery itself, sold nationally.

The fault is in the cells, not in the installation. In the ACCC's words, Tesla identified certain lithium-ion battery cells from a third-party supplier in a subset of Powerwall 2 systems that may fail and overheat. Tesla has had reports of affected units smoking or emitting flames, resulting in minor property damage.

The register also records that no injuries have been reported, and that most affected units have already been discharged remotely.

The sale window was originally November 2020 to June 2022. An amendment in April 2026 extended it to 23 August 2025. Articles written when the recall was announced still carry the old date, so yours may be inside the window now even if it looked unaffected in 2025.

How do I know if my Powerwall 2 is affected?

You cannot work it out from a serial number, because no list is published. The ACCC record says only that each unit has a unique serial number, and Tesla determines affected status per unit.

What you can do:

1. Open the Tesla app and confirm your battery is online. Tesla cannot flag or discharge a unit that is offline.
2. Look for a recall notification against your system in the app. That's how Tesla contacts owners.
3. If it's flagged, ring the company that installed it and book the replacement.
4. If that installer is no longer trading, Tesla handles it directly on 1800 958 369 (8:00 am – 6:00 pm AEST), by email at PWNoticeANZ@tesla.com, or through Tesla's Powerwall 2 replacement page.

What Tesla does about an affected unit

Tesla replaces an affected unit free of charge. It discharges the battery remotely first, to lower the risk while the unit is still on your wall. You may notice the battery has stopped cycling before you hear anything else.

A discharged battery saves you nothing on your bill. Tesla will consider compensation for those lost savings, case by case. Ask for it, because Tesla does not apply it automatically.

Is the Tesla Powerwall 3 affected?

No. The recall names the Powerwall 2 only. The Powerwall 3 is a different unit built with different cells, and it does not appear anywhere in the ACCC notice.

If you own a Powerwall 3, nothing on this page applies to your battery.

The Powerwall 2 today

The Powerwall 2 is a 13.5 kWh battery that needs a separate solar inverter beside it. The Powerwall 3 has the inverter built in and takes panels straight into the unit as DC.

We install the Powerwall 3 now. If you own a Powerwall 2 and it's working, it's a capable battery. The recall changes nothing for a unit outside the affected window. If someone offers you a used or old-stock Powerwall 2 today, check its sale date against the recall window first.

What a replacement includes

A replacement unit and a working system again. The swap restores the capacity you bought.

You may be wondering whether to move to a Powerwall 3 at that point, or to add capacity. The answer depends on your existing inverter, your switchboard and what you want from the system. An Energy Geek can work through that with you. Your replacement is free either way, so ask for any upgrade to be quoted separately.
