CR2032 batteries 4 pack from Energizer. Probably the best batteries I have used. Back on sale for a limited time on Amazon!
CamelCamelCamel.
For 6c extra, I'd buy from Amazon. Ease of refunds, etc
More of do you rush to buy this if it can be had for this price. But could be fake i guess.
It's just that too many fake batteries on eBay. Almost all Panasonic CR2032s on eBay are fakes.
Looks sketchy to me - pictures are a mix of CR2032 and CR2032H cells, and top review pictures show old package variant.
Reviews seem good though
I use these on my devices. They seem to last as long as they should, about 18 months.
Yeah I always grab these Maxell 10-packs. much better having the individual strip packs too, not to mention way cheaper. have used them in airtags, tiles etc and they go for ages. plus it's amazon, so if you get a shit batch you just refund it.
4x pack Duracell CR2032 on Amazon AU is also at very similar price range ($9.90, or $8.91 S&S = $2.48/$2.23 per cell)
Though I bought MAXELL high-capacity variant from this long-running deal, which is about $1.25 per cell. Worked quite well, too. (at least in cheap Tuya Zigbee sensors) But I'm transitioning to sensors with AAA battery anyway.
I've bought that brand before, but not from that seller. I used them in the humidity and temperature sensors. They didn't seem to last very long.
Mine is in red, double-layered blister packaging (battery is sandwitched between plastics instead of the more common between plastic and cardboard), 5x per plate. That's the reason I draw a conclusion of why I say the one from Amazon above looks sketchy.
Compared to my geniue Panasonic, it has a higher initial voltage and works better on my Tuya sensors. Now I'm about 4 months in and so far so good.
The child proof packaging on these is ridiculous, how is it necessary? are children eating coins laying around?????? Dessicent packs are literally just labeled "do not eat" and tossed right in the mix with food.
The child proof packaging on these is ridiculous
I 1000% agree, it's insane
Yes they do swallow coins but swallowed batteries are a horror story.
"are children eating coins laying around??????"
Yes?
Desiccant packs (silica gel) are non toxic. Button batteries if swallowed can burn through the oesophagus in two hours causing internal burns, severe bleeding or death. At least three children have died from swallowing them.
I absolutely hate the packaging, and in addition the batteries themselves now have a bitter coating applied to them that can cause issues for some devices (for example making them think that the battery has a low charge or even might not work at all) - requiring the battery to be cleaned with something like IPA to remove it.
On the flip side, just do a quick google search (eg https://www.poison.org/articles/button-batteries) and you'll see some examples of what can happen when a child swallows a battery. Young children discover the world around them by putting pretty much anything they find into their mouths. One of these things can burn through a kids esophagus in 2 hours - and a parent might not even know their child has swallowed one until it's too late. In Australia (https://www.abc.net.au/news/2023-06-10/button-batteries-pare…) about 3 children are taken to hospital every day due to suspected battery ingestion. So yes, it does happen, and children do die and many more suffer horrible injuries in Australia alone.
If I spend the rest of my life hunting for scissors to open up these packages, and wiping that annoying coating off cells - but in doing so the packaging prevents just one child suffering from injury then I'm happy to put up with the minor inconvenience.
Live with the inconvenience to save children's lives.
Sold!
Great find, thanks!
Wow. Thanks. Never thought to look for batteries there.
Free shipping, so got two for $14 delivered, bargain!
Thanks, i also got CR2025 2 for $4 from TGG Commercial.
there was a independant CR2032 voltage test on a website that revealed everything other than genuine Panasonic and Maxell were terrible. with most brands measuring well under 3V. while panasonic still managed 3V even after being left for a period in a low current device (I think months for the test). I think I remember some of the terrible performers even measured below 3V out of the packaging. this is usually only the case when you buy coin batteries that are on clearance and close to expiry.
funny thing is searching for that test of like 10+ brands I can't find it. maybe a certain company paid for it to buried in google results??
anyway this is pretty standard price for CR2032 on sale. but you can buy genuine made in japan Maxell coin batteries direct from Maxell Australia. they are based in VIC so I am out of state and delivery was $5 so it makes more sense to time it right and order a bunch at once.
I was about to run out so ordered 10x CR2032H (high capacity) awhile ago and it's currently $2 per battery (if you buy 10x). also ordered some other coin cells I needed. so +$5 shipping but honestly paying $2.50 per battery and these will last much longer than other brands.
I ordered awhile ago so paid about $2.30 per CR2032H battery.
manufacture date was 2022 and expiry 2033 which is 10 years pretty standard for coin batteries but you are paying for the actual quality and performance of the batteries.
I always say especially for medical equipment don't get any other brand other than panasonic or maxell.
here's the link to CR2032H (info says direct replacement for CR2032) https://shopmaxell.com.au/shop/batteries/micro-batteries/cr-…
("high capacity" Maxell CR2032H is 240mAh, panasonic CR2032 is 225mAh - according to table under "models" here https://maxell.com.au/shop/industrial-batteries/coin-shaped-…)
don't think anyone other than businesses needs 100x, but they also have a listing for 100x at $1.65 per instead of the $1.80 per on the page linked above.

I think H in primary batteries refers to both high capacity and higher nominal discharge rate. in this case there is a "never recharge primary batteries" written on the page, so I think it's just high capacity and Non-rechargeable.
- aliexpress page for a charger says LIR2032H is rechargeable, CR2032H is non-rechargeable.
higher nominal discharge rate in table linked above says it can handle 0.2mA of current rather than the usual 0.1mA. this means the battery is less stressed when it requires more power, such as making the loud sound play on Airtags.
also just be aware out of state shipping was a bit slow and took a few days, I guess they are using cheap shipping but that's fine you just need to check a bit more often if they have arrived because you probably don't want to leave these tiny batteries out in the sun. table says they can handle 85 degrees C but I just think they will last longer if less stressed.
Just wondering whether these have an expiry date? (Can I stock up for the future or is that not advised?)
You never know when you'll need a CR2032, but trust me, you will.
You'll probably need more than four. Literally everything uses these batteries.
My car keys chew through them like lollies, having to change them every year

Is it much of a deal?
