Maybe these are a better choice for longevity and value IMO.

Will see if they're available at my local Costco.
Hopefully the price will be cheaper in the Warehouse. Generally, Costco Online prices are a little bit more compared to In-store.

My Pokémon Go Plus goes through CR2032 batteries like crazy so I recently got Rechargeable CR2032’s. So far so good and I think I will save so much money in the long run.

I’ve had nothing but great success with the dollarama 3 pack of sunbeam batteries.

I use them in ecobee sensors and garage remotes and they last almost 13 months before the sensors start giving a low battery warning. I feel that’s fair for $1.25 I paid.

Saw them in Burlington for $16.99, which is the same as the online price.

Fyi those are fakes along with cheap Panasonics, lots on AliExpress as well. Bought some before and package says made in Japan while batteries stamped Indonesia.

Been burning through CR2032s with some cork/fairy light strands - Dollarama ones weren't lasting all that long (IMO) so good to see some other options here.
I had seen an even better price at Princess Auto a couple of weeks ago but haven't had time to see if they still have them in stock. "Special Buy", seemed to me to be 5 for .88 or something, so probably nothing great, but at least cheaper than Dollarama's. Their website doesn't show anything for .88, though, at the moment.

Aliexpress rechargeable cr2032, get a kit that comes with the charger and batteries thrown in "free". Make sure the plug is usb or U.S.

The first time I bought Sony CR2032 from Ebay they were cheap and lasted long. The second time there were terrible. Not sure if they were fake or old stock. According to the expiry I think they might have been fake.

People here seem to hate on the Dollarama Sunbeam ones but they seem to work well enough for me.

I just found out some key fobs are like ~$400. I'd hate to have a cheap button cell leak in a fob.

(can these leak like an AA? I've been told all batteries *can* leak given the right circumstances)

These button cells don't leak. They are not alkaline.

Yes. As the Thread Title states: Lithium

I bought these "cheap" batteries from Dollarama for 3 or $4. They didn't have enough juice to power my key fob and are not returnable at Dollarama. Lesson learned.

I actually use rechargeable CR 2032 batteries from Aliexpress. You can buy a kit that comes with a charger AND rechargeable CR2032 batteries that can be charged hundreds of times. Search for "coin battery charger" and make sure the plug is USB or says U.S. Plug.

In your experience, how long do the batteries last before needing to be recharged again? This would be very useful to me, but what I need it for is kind of a pain in the ass to swap the battery out so if it's a short amount of usage before needing to be recharged then it might not be for me

I think ALL brands are hit or miss.

I've used Dollarama, Ikea CR2032 batteries and some were good, some were crap. Quality Control?

For me, Energizer and Sony batteries have been reliable and consistently good.

I asked a question, you're correct.

just like the person that posted the exact same thing, directly above you, 12 hours before you..

..so..

Go you?

I have no name rechargeable CR2032 ones from Aliexpress that I got with the charger. They last as long as the Dollarama ones in my Pokémon Go Plus ( a bluetooth device to play Pokémon Go, very high/heavy usage, 2-3 months in this device, again HEAVY drain hence the short life). The black charger has two slots and two UK Prongs, looks like it's going to catch fire at any moment. I suggest the more expensive looking one LOL.

You sure they are counterfeit Sony CR2032?

According to this, I have the package with the Blister over the number, it's original (*shrugs*):

Out of curiosity, I have purchased Duracell 2032 at Costco and these cheap LiCB batteries on Amazon. I have decided to test both batteries in order to compare the value as I was interested to know where to invest.


Here is some basic info:

Duracell
Price: $1.41 per battery
Expiry: 2030

LiCB
Price: $0.25 per battery
Expiry: 2022

Testing
For testing, I wrote a small Arduino program to log the time and voltage of both batteries every 30 minutes. The information was saved on the SD card and then imported into Google Sheets. The test lasted 53 hours but after 25 hours I already got enough data. To simulate real-world scenario as close as possible, I put a small load (2 LEDs) on each battery which provided around 10mA load. The cut-off voltage for this test was 2V. When the battery drops below 2V under 10mA load I would consider it dead.


Conclusion
The Duracell battery reached 2V after 26 hours, while the LiCB battery lasted only 12 hours. In this scenario, Duracell easily outlasted LiCB but I would still go for LiCB battery for non-essential devices. For example, my smart home door sensors use extremely low power and LiCB would last for long enough to justify 5.6 times price difference. When the battery is low, the sensor would notify me and it takes less than a minute to replace it. For devices like the bicycle light, I would probably go with Duracell as those batteries had higher voltage from the start and would provide brighter light for a longer time, which is important for safety. FYI: In many cases, these batteries would work even below 2V as some devices don't use much juice. Also, keep in mind that LiCB batteries had a short expiry date and that newer batteries could potentially last significantly longer.

That's it from me. Take a look at the chart below. I hope this would help you make your own conclusion. If you are interested I might test other batteries as well.

I think technically those aren't CR2032 anymore, they're LIR2032. Chemistry, discharge characteristics and most importantly voltage are different (3V vs 3.6V), so they might not be drop-in replacements.
