GutAlkaLi CR2450 Lithium 3V Battery, Electronic Coin Cell Button for Toys Calculators Watches (40 Pcs)

Good generic batteries. They seems to work just as well as the name brands.

We used these for some LED tea lights. They seem to suck batteries down pretty quickly, but these lasted a decently long time.

Not sure if it's the battery or the little puck light LEDs I'm using them in, but they don't seem to last very long. Should mention that I haven't found any that last any longer than these

I have to purchase these pretty regularly since I sell flower crowns with fairy lights in them and the customers often need fresh batteries with their purchase. These came well packaged and look very quality. I haven't tested their life span since I use them for customers. I am just happy that they are so affordable!

I’m not sure about battery life yet. I will update as I test them out. But great value for as many as you get. So far all that I’ve used were charged and without. Of course I didn’t use them all so it will be interesting to see how long shelf life is as well

They work great in my wife’s outdoor candles

These come in what they describe as childproof packages. However, in my experience, they're just plain people proof. Each individual battery has to be cut from the packages that have 2 layers of protective plastic encased in the cardboard boarders & backings. This is challenging to do with hands weakened by tendonitis and arthritis. The batteries themselves are also slightly smaller than others of its own class. I've purchased many different brands of CR2450 's & these are the first ones I've come across that don't quite fit inside product battery compartments. But the battery life is adequate. I have no complaints there. I decided to keep them because I have some LED tea light candles that have extremely tight battery compartments, making the removal of batteries difficult. These work quite nicely for those candles, once I can surgically extract them from their mothership. So, all that said: Decent battery life. Small size. Tyrannical packaging. 3/5 stars.

Great value. Of course I wish they could last for months. But must have candles and much safer than flame candles. Must have!!
