Duracell 21/23 12V Battery, 2 Count (Pack of 1), 21/23 12 Volt Alkaline Batteries, Long-Lasting, Key Fob, Alarm Sensor, Garage Door Openers, and More

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.

Great batteries & long lasting

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?

Reliable an did the job!

The product was exactly what I needed and works great. I knocked off one star due to Amazon's slow delivery. It arrived several days after it was supposed to.

These can be hard to find so I appreciated being able to buy a 2-pack so I have a spare on hand. Appears to be long lasting so far.

Good quality battery.

Now the final crunch days before Christmas, I diagnosed my entire yard’s light display failure had to be due to the master remote’s battery (even though the remote’s red light kept working). When I popped the remote that controlled it all open, I discovered the tiniest cylindrical battery I’d ever seen. I thought, no company on earth could possibly sell that size. I went onto Amazon, found the closest size (“21/23”), and ordered it with overnight shipping. A half day later, the package was on my porch. 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.
