Brightown 20 Count CR2032 Lithium Coin Cell Battery, 3V Blister Packed CR2032 Button Battery for Small Devices, Long Lasting Power, 8-Year Storage Shelf Life, Child Secure Packaging, Pack of 20…

For the amount of batteries you get it's a great value. I have used 2 so far and still more to go to use the rest. I think this will last me at least a couple of years. Used one in a brand new car key and the other in a red dot optic. Both worked perfectly.

The batteries seem to be fully charged. I would buy them again.

What can I say...They work and they’re reasonably priced although I do wish they would last longer. I don’t use them 24 hours a day... about 4 hrs. I wish I could find some fairy lights that used AAA or AA batteries and you could use a remote with them I have my bottles on top of my cupboards, near the ceiling so changing the batteries is quite a hassle.

First set of batteries we purchased, not ONE battery from the package worked. However, their customer service dept did send a replacement and the second package seems to be fine (the first battery we pulled out worked, haven’t tested the rest of the package). It’s a good price and customer service ensured that we were satisfied.

Muy útil

package was easier to open they fit fine i guess your just supposed to know that the waffle design is the minus side and clear is the plus side having never bought this type before was a learning expierence

I don't know why I have not learned the lesson yet, that purchasing off-brand or unknown-named manufactured batteries often leaves me disappointed. These batteries advertise an 8-year-shelf-life, however, it is not apparent when the 8-year countdown begins. I should have noticed while scrutinizing the pictures accompanying the advertisement that there seems to be a contradiction with the "8-year shelf-life" guarantee. The picture under the title Efficient Leakage Proof, it clearly indicates "3-years" shelf-life. I'm confused. How did this item receive an average 4.4 rating? Did I just receive a bad pack? After less than two years, stored in a case designed for battery storage, in a cool walk-in closet, the batteries tested at almost 3-volts. We're good, right? Not necessarily. The battery test meter places almost no load on the battery when reading voltage, however; if you leave the battery in the tester while holding the button down, the voltage will quickly drop to almost nothing. How did we discover this tragedy? Subsequent to replacing the battery in our vehicle security fob. Three days after, we were stranded as the battery didn't have enough of a charge to operate the security fob. When we got home, I tested around a dozen of the remaining batteries. No surprise, same result. Dead within seconds of being put under test load. BTW, we just happened to be near a wholesale club where we purchased a pack of Duracell batteries for over $30. You get what you pay for. As a result of our unfortunate experience, we tested every one of the Duracell batteries once we got home. All tested at or above 3-volts even under a load. DO NOT BUY CHEAP BATTERIES UNLESS YOU WANT TO EXPERIENCE THE CIRCUMSTANCE WE DID. Very Disappointed!

These last as long or longer than the name brand and for about 25% of the cost. I normally a name brand battery buyer all the way in fact I buy the energizer lithium batteries for everything I own but I was using a laser level at work and was going through batteries like crazy which was costing me about $80 a week so I took a chance and baught these. I was skeptical but figured that if I even used 3 times the batteries it would still save me money so they just had to fall within those boundaries and I would be fine and to my surprise they held their ground and ended up only having to spend $15 a week compared to $80. A huge savings! I will now see what other sizes of batteries this company produces and try them because if they perform as well as these then ill be saving money left and right.
