why buy at store? quality and fast delivery

I ran a little test. The results were pleasantly surprising. I bought Duracells at ≈$3 each (pictured right), and these Nightkonics at ≈$0.50 each (pictured left). I put 9 of each brand into 18 candles, and set them to run 4hrs everyday. After about 40 days I noticed many of them had either died, or gone dim, so I decided to gather them back up and group them by brand to see how it went. The results told me I don’t need to spend nearly 6 times the money for the same battery life in my little candles. These Nightkonics seem to be the real deal. I feel a little ridiculous running this test, but I wanted to know for sure if these were actually worth the money. And hey, if I’m able to help others with my ridiculousness, well that’s pretty cool too. Cheers!

Ordered them, used them in some welding helmets, working just fine.

These batteries are pretty useful for remote controls, weighing scales, etc. I've used them for just over a month now and wanted to see if I ran into any issues but I am happy to report that they have been working as I had hoped. In the past, I have experienced certain batteries to have some discharge/leakage and while I cannot remember the timeline for something like that, in the 6 weeks I have used these I have run into no issues whatsoever. I also love that it comes in a 20 pack because I hate when they are sold in the 2 packs as they often are at Walgreens or similar stores. This is particularly useful if you have many devices that require this type of battery. it is also really nice to have them stored up just in case you need one on a moment's notice.

I needed these batteries to replace the worn out batteries in my sensors. Walgreens were sold out. So I tried the Amazon product. Great deal. For the price of 2 Walgreens 2450 batteries, I got 20. How long these batteries will last, only time will tell. But so far it's held up.

You can't beat the price! Great value for the money . They cost 3x more in some of my favorite stores out there. They worked perfectly. However, I cannot comment on the longevity yet.

I use these in my battery operated timed candles. They are timed for 6 hours on and then off. One battery lasts for at least two weeks!!

About a month in the PIR sensor and 2-3 months in door sensor (zigbee)
