Duracell 21 23 12V Battery 2 Count Pack of 1 21 23 12 Volt Alkaline Batteries Long-Lasting Key

These batteries have been hard to find for me so I'm glad to have them here. They work well in the remote for my camera so that I don't have to run back and forth taking pictures I need to be in. They have a pretty good use life as well and the price lines up with what I see in stores. Read more

Great ceiling fan remote replacement! Our ceiling fan has a remote to control operation, but with a dead remote, there is no controlling it!!! Amazon delivered new batteries over night and at a great price! These are a special size battery, probably won’t find easily in a store. Maybe at a camera shop? Read more

I opened the package, opened the blister pack inside, and compared it to my likely-dying battery. The new ones looked an eighth inch longer. Holding my breath, I was still able to slip in the new battery, and pressed “On.” To my delight, my entire yard display lit up like a beacon. Read more
