40 Pack CR2032 Batteries, 3V Lithium Coin Battery for Small Electronic Devices, 5 Year Shelf Life

I don't know for sure, but I would bet that virtually all coin-cell batteries sold under numerous brand names are made by a small handful of companies that track each other and any improvement to the technology by one, is readily incorporated by all, so that all the batteries are virtually identical. Consequently, shopping by price, which I have done for years with very few disappointments, makes sense. At the time of purchase, these PGSonic CR2032 batteries were the best deal I could find on Amazon, or anywhere for that matter, and so far, the few I have used are working fine. With a 5-year shelf life, buying in bulk makes sense as well.

My ring alarm sensors were needing to be replaced and this value pack was exactly what I needed. So far I've used about 16 and all worked well and seem to have enough power to last a few years.

Fast delivery and the price is much better than I have seen in stores.

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 @ $9.99POWEROWL (20) batteries x 72 hours = 1,440 hours @ $8.98POWEROWL (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.

Great for my battery candles
