Tenergy 1.5 Volt Battery Button Cell LR41, ag3 Batteries Equivalent, Ideal for thermometers, Watches, Laser Pointers, Small Toys, Portable Electronics, 20 Pack

The batteries work great/but for a very short time! Problem is MOST OF THEM WERE DEAD WHEN I RECEIVED THEM AND OTHERS WENT DEAD A FEW WEEKS later! IN MY thermometer they went dead after the thermometer was only used only twice!!!Will NEVER BUY FROM THIS COMPANY AGAIN!

Tested 5 batteries brand new right of the package with Klein 660 volt meter all measured .8-.9 volt.None measured the advertised 1.5 volts.More Amazon recommended garbage.

First 3 batteries I pulled were completely dead. Next 3 were fine. I guess they send this many because HALF OF THEM ARE DEAD ON ARRIVAL. Buy Duracell instead.

I've used Teneegy for a few years and batteries are dependable from medical devices to solar light batteries.

Got these to swap out my daughters little toys. Lamps in her doll house, annoying voices on the cars, lights on bracelets...these button batteries are 3to5 each in stores so grabbing bulk was a no brainer. They dont seem to be as bright when in lights or last as long, but for the price i ain't complaining.

Work great have them in about 9 diffrent items and all work great

These were just what I needed for several Christmas decorations. They cannot be found anywhere in the stores. Batteries + is too far from me.

I have a small flashlight that has a whistle for safety. The light wasn't working so I removed the batteries and found the battery number I ordered these batteries. Everything worked perfectly. The item is also delivered before the time it was promised.
