Love these batteries!!!
I initially ordered these for small tea lights with dead batteries. I actually thought the lights were disposable because I figured it would be cheaper to buy new ones than get “specialty batteries”. I was pleasantly surprised to find these CR2032 at such a reasonable price. I didn’t really need “40” but what a great deal! Well, who knew I needed these batteries more than I knew. My dad’s talking watch for visually impaired individuals needed a new battery. Guess what? It takes CR2032 and I was able to replace it for him rather than take it to jeweler. Not long after my key fob needed a new battery and guess what? Yes, it takes a CR2032 battery and I replaced it myself. I will now be keeping this battery size in my arsenal! I love being able to do these small tasks and saving a lot of money in the process.

Surprised of out of the packaged
So these are not your name brand battery and was expecting for some to be dead out of the package and they were not. Had to replace 10 of my alarm sensor batteries and all reported back full strength. No issues going on a couple weeks now and a couple of the sensors get used quite a bit and the sensor still show full strength

For Those Who Use These Batteries For Tealights
My primary use for these CR2032 batteries is for tealights. If you’re like me in enjoying many tealights for creative lighting as well as not wanting to spend top dollar for premium lithium CR2032s, then read on. My review below contains general data on these batteries re: Usage ( hours of light ) / Price . The kind of basic and pertinent data that I find helpful when seeking out Amazon reviews on lower-cost items, though such items bought frequently can add up! Hopefully, this review will aid in your decision-making.My Test: Comparison of Usage / Cost of PGSONIC VS POWEROWL CR2032 batteries.Simple Usage: I inserted (1) battery into (1) functioning tealight and observed over days how long each burned brightly and clearly until dimming to 1/2 as bright or lower of visibility. I never turned the tealight off during each test.Results: (1) PGSONIC battery lasted around 48 hours +/- 5 hours lit brightly, then soon dimmed to 1/2 as bright, finally fading out by around 58 hours. (1) POWEROWL battery lasted around 72 hours +/- 5 hours lit brightly, then slowly dimmed to 1/2 as bright. finally fading out around 80 hours.Usage / Price: PGSONIC (40) batteries x 48 hours = 1,920 hours @ $9.99 POWEROWL (20) batteries x 72 hours = 1,440 hours @ $8.98 POWEROWL (40) batteries x 72 hours = 2,880 hours @ $13.98 [ 6.99/(20) pack x (2) = $13.98 ]***The price of $6.99 / (20) pack on the POWEROWL batteries is the price I saw recently on Sale. Of course, include Tax in your calculations / cost as well.***Bias: For my preference, I counted the hours where the tealight burned clearly and strongly up until it was 1/2 as bright. At that point it is not so enjoyable of an accent light, i.e. time to change out the battery. My preference. You might prefer how much longer the POWEROWL batteries last even when 1/2 as bright and slowly dimming down further, thus, something to consider in terms of the enjoyablility-usage factor.Disclaimer: I only tested (1) of each brand’s battery. Sorry, I wasn’t about to test (20) of each. I’ve purchased the POWEROWLs a few times and found them relatively consistent, though not perfectly so in longevity. This review is a general overview and experience with their batteries and now the PGSONIC. Basic reflections to consider. As I use the PGSONICs I will return to edit this review if there is any remarkable and consistent difference in longevity-usage.Conclusion: For those who care about longer hours of clear, bright light and lower cost, PGSONIC gives you around 500 hours more of light for a dollar more when purchasing (40) of PGSONIC VS (20) of POWEROWL NOT on Sale. When the POWEROWLs are on Sale for (20) @ $6.99, then it’s around the same cost when adjusting for a reasonable expectation of 2,880 total hours of clear, bright light from either brand. (40) Powerowls on Sale bring you 2,880 hours of enjoyable light. You would have to purchase roughly $5 more of PGSONICs, [ (60) total ] for that many hours worth.

Best Value for the $$
These button cell batteries are fantastic, can be used for so many things. I bought them for tea lights & then discovered that they are also the right size for scope on hunting rifle. I craft a lot & these work in fairy lights I have as well, easy to install too!
