Duracell MN21B2PK Watch/Electronic/Keyless Entry Battery, 12 Volt Alkaline

Works great and a good price.

Works as designed

Great batteries for the Minka Aire remote! Long lasting.

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.

They are Duracell they are always good

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.

Everything is great.

Works perfectly with my MinkaAire fan remote.

Good

Muy buena batería pero algo elevado en el precio

I bought these for the quality and reliability. I won't know that until they have been used for a few months.

Good!
