LR44

Used it for a frog terrarium humidity/thermometer. Works fine. I have no idea how long it will last, but it's a Maxell, it was in its original packaging and seal, and at 1/4 the price of Wal-Mart.

I bought these to replace button batteries not made any more. They fit and they work! Very happy.

Just what I needed, quick delivery, great service!

They came with 4 batteries as ordered. The price was half as much for 4 batteries as compared to a big boxed store 2 battery pack. Took a few days to get them but I saved dollars. The first 2 worked just fine in a toy I had here for my great-granddaughter.

This reseller cut four cells from a larger card. This is of no particular consequence.My issue is that the three remaining cells have a short shelf life through 2028. The thermometer utilizing the button call has been in use for over four years. I expect that I will need to discard / recycle all four cells at about the same time. I hope that the recycling can reduce the hazardous materials quantity from entering our water

Good item just what I was needed for

Purchased for use in my1970's and 80's era Pentax cameras. They work just as well as the more expensive Energizer equivalent at a fraction of the cost. No more power than what these cameras use, I suspect these batteries might be the last set I need for a very long time.

I have had experience on junk like this before. Often, Amazon never gets it and charges my card. I did request a replacement and sent the defective one back. Tried 3 of the 4 batteries in the pack and none would work to start up my thermometer. I tested each of the batteries and every one had low status reading. They put a stick on the back to cover up the date to trick you so you can't see I reckon.
