The Powerwall 2 recall: is yours one of them?

The 30-second take

• It is a real, current recall. Tesla Motors Australia issued a voluntary product safety recall for certain Powerwall 2 home batteries, listed by the ACCC as PRA number 2025/20611.
• The dates matter. The notice covers units available for sale from 1 November 2020 to 23 August 2025 — an update in April 2026 extended that window.
• The cause is cells, not installation. The notice describes lithium-ion cells from a third-party supplier that "may fail and overheat", with a stated risk of fire that could cause serious injury, death or property damage.
• It is a subset, not every Powerwall 2. Owners are told to check the system is online and look for a notification in the Tesla app.
• Check the live notice, not a news article. It has been updated twice in 2026 — most recently on 12 August 2026 — so any summary written earlier may already be out of date.

What the recall actually covers

On 16 September 2025 Tesla Motors Australia Pty Ltd issued a voluntary product safety recall for certain Powerwall 2 home batteries. The ACCC lists it under PRA number 2025/20611, and the notice has been updated twice since — on 13 April 2026, which extended the range of affected sale dates, and again on 12 August 2026.

The affected units are those available for sale from 1 November 2020 to 23 August 2025. That is a wide window covering a large share of Australia’s installed Powerwall 2 fleet, which is why the notice is careful to say the fault sits in a subset of systems rather than in all of them.

• The defect. Certain lithium-ion battery cells from a third-party supplier "may fail and overheat".
• The stated hazard. The notice warns of a fire that "could cause serious injury, death or damage to property".
• The product. Powerwall 2 only. Powerwall 3 is not named anywhere in the notice — including, contrary to a good deal of secondhand reporting, as the designated replacement unit.
• The remedy. Affected units are replaced at no cost to the owner.

How to check whether yours is affected

You do not need to work this out from a serial number yourself. The notice sets out a short check, and the identification runs from Tesla’s side.

• Confirm the system is online. A Powerwall that has dropped off the network cannot receive the notification, which is why this is step one.
• Check the Tesla app for a notification telling you whether your specific unit is affected.
• Contact your original installer to schedule the replacement — that is the action the notice directs owners to take.
• Read the notice itself, linked in the sources below. It is the only version guaranteed to be current, and it has already changed twice this year.

If your original installer is no longer trading — a real problem for anyone who bought on price from an operator that has since folded — you are relying on finding another business willing to take on someone else’s warranty work. That is the cost of a cheap install showing up years later, and it is worth knowing before you choose who fits your next system.

What a recall does and does not tell you about a brand

It is tempting to read a recall as proof that a product is bad. The more useful reading is closer to the opposite: a recall is the visible part of a regulatory system doing its job. The Clean Energy Regulator made that point directly when it covered this one, framing it as evidence the safety framework around home batteries is working.

Cell-level defects from a component supplier are a manufacturing risk every battery brand carries. The honest comparison is not "which brand has never had a recall" — it is how quickly a fault is identified, how clearly it is communicated, and whether the fix reaches owners without cost or argument. A documented recall with a free replacement and an in-app notification is a better outcome than a quiet fault nobody publishes.

“A recall is the visible part of the system working. The invisible part — whether the person who installed your battery is still in business to do the replacement — is the part you actually chose.”

Where this leaves your next battery

If you are buying now, this recall is not a reason to rule out Tesla, and it is not a reason to relax about anyone else either. What it should change is how much weight you put on the installer relative to the badge on the wall.

Battery installation quality in Australia is measurably uneven. The Clean Energy Regulator inspected 1,278 home battery installations between July 2025 and April 2026 and classified more than 60% as substandard and 1.2% as unsafe. Most substandard installs keep running and need paperwork, labelling or signage rectified — but the spread tells you the install is where the variance lives, not the cell chemistry.

Get matched with 2-3 vetted solar installers — businesses with typically 2+ years of trading history, a track record of decent reviews and a written workmanship warranty. Which is another way of saying: someone who will still answer the phone if a notice like this one lands on your system in year six.
