What buyers say about Nightkonic 20 pcs Pack - CR2450 Battery 3v Lithium Button Cell Coin 2450 Batteries
I have been using these batteries for a month now and am happy to report that they have worked as I had hoped.
Nightkonic batteries are well above the average producer and their package sizes, price per battery, and number that arrive full charade has been very above my expectations.
I use a lot of CR2450 batteries in my home automation door/window sensors and replace them frequently, they last almost as long as the brand names, but without the high price and quantity.
I feel like I'm being crazy by running this test, but I want to know if these are worth the money, and if I can help others with their crazyness.
I have never used batteries from this brand before, but they seem to be very well made and charged, and are a lot bigger and thicker than the most common CR 2032 batteries.
