Some batteries being quoted todayhave already lost their approval.
A battery earns the federal certificates only while its exact model holds a current listing on the Clean Energy Council approved battery list. Listings expire. Stock does not. As at 2026-08-20, 158 of the 3526 registered configurations had already lapsed, and 82 more lapse within six months.
Quick answer
As at 2026-08-20, 158 of the 3526 configurations on the Clean Energy Council approved battery list had already passed their expiry date, and 82 lapse within six months. 35 product lines have no current listing left at all. A lapsed listing means that model can no longer earn small-scale technology certificates, so the federal discount does not apply to it — the hardware is not unsafe or recalled, it is simply outside the scheme. Eligibility is judged on the installation date rather than the contract date, which makes this a live risk on long lead times.

Why this is happening now
The requirements underneath the list are being replaced.
The approved list was built on the Clean Energy Council's Battery Safety Guide. In October 2025 Standards Australia published a technical specification for home batteries, SA TS 5398, which supersedes it, and the Council is phasing the new specification into the listing requirements. As part of that transition it brought the expiry dates of more than 700 listed products forward, and the effect is visible in the register today: 2947 configurations now share a single expiry date of 2027-12-31.
For a buyer that means two things. Products will re-list against the new requirements and most well-supported ranges will come through fine. And for a window, the register will carry more lapsed entries than usual — which is precisely when a quote is most likely to name one.
No current listing at all
35 product lines have lapsed entirely.
Every registered configuration of these lines has passed its expiry date. If one of them appears on a quote, the certificates are not available for it — that is worth raising before anything is signed rather than after the invoice arrives.

A product line is one family, andsizes is how many separate configurations of it are registered — modular systems are registered once per stack size, which is why some lines show dozens. Usable capacity is the figure the certificate tiers are calculated on, and it is always lower than the nominal capacity printed on the box.Listing expires is the date the Clean Energy Council approval lapses; after it, that configuration can no longer earn certificates. All of it is as published in the Clean Energy Council approved battery list, so you can look up any line yourself.
Lapsing within six months
Where lead time becomes the risk.
These lines still hold current listings, but at least one configuration lapses inside six months of 2026-08-20. Because eligibility is decided by the day the system is installed, an order placed now against a long lead time can arrive on the wrong side of the date. Sorted by how soon the first configuration goes.

How to check in ten minutes
Four things, off your own quote.
- Find the model number. Not the brand and not the series name — the model number. "A Powerwall" or "a SMILE system" is not specific enough to check, and that ambiguity is where the problem hides.
- Look it up on the register. The Clean Energy Regulator publishes the whole approved list as a free download. Search for the model number.
- Read the expiry date, not just the presence. Being on the list is not enough if the date has passed — or if it passes before your installation is scheduled.
- Compare the usable capacity. If the register and the quote disagree, ask why before assuming the quote is right. Usable and nominal capacity are different numbers and quotes mix them up.
Figures on this page are computed from the Clean Energy Council approved battery list, published by the Clean Energy Regulator as published on 2026-08-20, and are rebuilt whenever the register is.

Lapsed battery listings — common questions
What actually happens if the battery on my quote has a lapsed listing?
No certificates can be created for that installation, so the discount that was quoted on the assumption they could simply does not arrive. The battery itself is not illegal, unsafe or unusable — a lapsed listing is an approvals status, not a safety recall. It means the product is no longer covered for the purposes of the scheme. The practical result is a bill that is larger than the one you agreed to, and an argument about who wears it.
Why are so many listings expiring at once?
Because the requirements are being replaced. Standards Australia published a technical specification for home batteries, SA TS 5398, in October 2025, and it supersedes the Battery Safety Guide that the approved list was built on. The Clean Energy Council is phasing the new specification into the listing requirements, and in January 2026 it brought the expiry dates of more than 700 products forward as part of that transition. Manufacturers re-list products against the new requirements; the ones that do not, drop off.
Does a lapsed listing mean the battery is unsafe?
No, and it would be unfair to the manufacturers to read it that way. Products lapse for ordinary commercial reasons — a line is superseded, a company chooses not to re-certify an older model, paperwork moves at a different pace than the transition. What a lapsed listing tells you is narrow and specific: this configuration cannot generate certificates. Judgements about the hardware itself belong to the warranty, the specification and the installer, not to a date on a register.
How do I protect myself on a long lead time?
Two things, both reasonable to ask for and both cheap. Get the model number and its current listing expiry date written into the quote, so there is no ambiguity later about which product was agreed. Then ask for a clause covering what happens if the product is superseded or its listing lapses before installation — who bears the shortfall, and whether you can substitute an equivalent listed model. Since eligibility is decided by the installation date rather than the contract date, this is the buyer's risk by default unless someone writes down otherwise.
