50 Pack CR2450 3V Lithium Coin Cell Batteries - Long Lasting Power for Watches, Calculators, Key Fobs & Medical Devices

Well for the money they seem to be fine but they don't last very long when you think I these kind of batteries you think watch batteries last a long time day and night these batteries lasted about 3 days tops so they don't have a life long period but they still work for the price I guessThe batteries did not last long. I used them in party lights. The type of battery should have lasted about 36 hours in those lights (based on previous uses and directions). These ones only lasted about 8 hours. Would not buy them again. They were cheap dollar store quality.haven't had them long enough to tell how long they'll last, however they are slightly different from other brand of same sizeI received the generic Wama CR2450 instead of the Powertron. These were pretty weak and only lit my flameless candles at ~ 75% brightness. The CR2450 batteries by EmazingLights are slightly more expensive but deliver more power.I like to buy them, they are cheaper and last much longerI started with replacing the battery in my window sensor for my house alarm system. I went through ten batteries, and they all have no or very low charge and will not work. Don't waste your money or time purchasing these useless things. I don't know what they are, but I know they are not useful batteries, they are garbageTried numerous batteries for my car remote and all the batteries were dead. Reached out to return them for a refund & I was going to have print a label & box these things back up to ship back. They were only a couple bucks. Not worth my time. They should have offered to refund my cost without returning DEAD batteries!! Will not buy from them again. Lesson learned!The batteries didn’t work, period. The Seller asked why I wanted a replacement if I wasn’t satisfied with the batteries. It’s not worth the fight. Terrible Seller. Be wary.
