Like last year, Battery World will be running a 9v battery swap program nationally over 3 days. I've confirmed this via their HQ and a number of stores. Only difference is they've dropped the limit to 10 batteries per customer. These are heavy duty carbon-zinc batteries that are (according to Battery World) perfectly suited for smoke alarms. Enjoy :)

The pun force is strong with this one
minor adjustment for next time: "keeping us in the eneloop" -> "keeping us eneloop"
Time to stock up on batteries now?
You can't stock up, it's new for old, and they are carbon batteries so you wouldn't want to store them anyway.
What’s the difference between carbon zinc batteries and alkaline (presumably the existing battery for smoke alarm)?
different battery tech obviously. zinc-carbon good for slow draining type such as clocks or smoke alarms etc. alkaline suitable for power hungry fast draining ones such as toys.
All the advice about smoke alarms I've ever read says to use alkaline or lithium batteries, not carbon zinc. Seems like a dud deal to me.
Read the same and in other countries as well saying always replace with an Alkaline battery.
If you replace the battery prophylactically every year, carbon battery is gonna be fine.
If you want it to last a long time, buy an alkaline battery.
Max 10 per customer? BRODENS to the front of line.
No large public gatherings,no deal
Wont be able to go if this gets 500 or more +votes so only + if you are going 😀
I've spent all this money on smoke alarms and we have not even had a single fire.
Be careful what you wish for… :x
So, do people replace their batteries while they still have life in them? Or wait for the low battery alarm?
The usual advice is to replace them once a year. Some people suggest doing it when daylight saving starts or ends so you’ll always remember.
1st of April is the date the firies recommend.
I know the advice is to always change batteries at the daylight savings time changeover. There was an ad campaign a few years ago "Change your clock, change your smoke alarm battery". That ad is still in my head. But despite the messaging, I wait until the low battery alarm sounds.
I just wait until the smoke alarm chirps at me. I do keep a spare just in case the smoke alarm chirps at 2am.
No dealers within cooee of me. Maybe if I do a day trip, cut lunch, etc.
But good on ya for posting the info.
FYI a few moons ago I bought the Aldi two pack 9V alkaline expiry 2024, put it in my smoke alarm, no good still beeping, swap to next Aldi 9V same thing. Maybe a bad batch, maybe higher than normal internal resistance. Can't stand the beeping went out to Woolies instead got the Chevron 9V expiry September 2024, works nicely.
Original battery is a Duracell industrial 9V alkalinr lasted whooping 8 years but then again this is a 240v mains powered smoke alarm with 9V battery backup.
Let's see how long this Chevron will hold up. The price difference too tempting.
You can get a Duracell Industrial (Procell) Battery battery for $2.18. If that lasted for 8 years why would you go to the WW Chevron brand?
i got a bunch of green rechargable Chevron batteries on clearance from BigW, they seem to last longer than my eneloops.
This would be cancelled right? Max 10 ppl social distancing etc?
2 people now . not sure if store will still be open?
looks like still on - with no limits to buying batteries:

Good deal. I had 8 expired 9V batteries that I was originally going to take to Aldi for recycling, until I saw this deal. This morning at Battery World they were happy to exchange them all for new ones. I can easily use that many in smoke alarms at my place and other family & neighbour households.
Must pop into Aldi to see if there are any 9V batteries in the recycling bin before taking up this offer😉 Only have 3.
Great deal, just be aware that smoke detectors are also meant to be replaced every 10 years (https://www.fire.nsw.gov.au/page.php?id=9218)
how does this work exactly? just walk in with old batteries?
Yes, they will swap them for new ones (up to 10 batteries).
"Customers can bring in up to 10 of their old batteries for us to recycle and we will give them new batteries free next week from April 1 to 3,"
Asked $1 each at my local shop. (Wantirna)
So they didn't honour this deal to you?
Nah but didn't mind pay $1.
Went to Batterie World O’Connor WA and asked to exchange 3 batteries for free. Apparently they had never heard about it. After confirming with the manager they charged $1 per battery.
Right, so just got back from Battery World Wantirna (VIC). A couple of friendly gents behind the desk eyed me suspiciously as I approached with my bag of old batteries. They told me it's not a real thing, head office confirmed it wasn't a real thing, and I'm the third Ozbargainer in there after the same deal… but very generously did the swap anyway (sorry they charged you, Pilmarion)
So, the staff not knowing about it and the complete lack of promotion of the deal leads me to ask: is this a well-planned Tightarse April Fools joke?
Not at all. I called their HQ on March 13 and had confirmation it's nationwide. That's why I posted on the same day.
Well I don't know what to do with that- trust the internet stranger who appears adamant, or the staff at the store who were adamant?
What triggered you to ask on March 13? There's been no promotion of it at all.
TA has helpfully posted this Deal before. This annual promotion has been running for a few years. I've never had any problem picking up free batteries.
Mt Gravatt Brisbane store was prepared for the promotion, happily asked how many I wanted to swap, & handed them over. The computer was set up to charge $0 for each battery. Too easy!
The joke is with the shop. My local battery world is staffed with people who would not give you anything for free, regardless of what head office said. It is also one of the reason why I’ll never buy anything from them due to past experiences.
picked up 13 they didnt even bother counting them just asked that i throw them in their recycle bin. they reminded me it was only meant to be 10 and asked how many smoke alarms i had. i said it was also for my mums house too as she is isolated. it was all good this time round. some staff dont know about promo and give you a hard time as in past years.
Just to save myself and others the effort…
