Great Value and Reliable Power
Cayla—June 14, 2025
I needed these for a couple of small remotes, and this 4-pack was a great deal compared to buying singles at the store. As expected from Duracell, the batteries are reliable and long-lasting. They come well-packaged with a decent expiration date, so I know I can keep the extras on hand for future use. Definitely worth it if you use these types of batteries regularly. Highly recommend!

This product was exactly what I was looking for!
Rose—July 11, 2025
I recently purchased the A21/23 Duracell Battery for overhead ceiling fan and light remotes. While many brick-and-mortar stores were either sold out or did not carry the product, I was able to order a pack of four batteries for almost half the cost of competitors. Before I knew it, the battery quickly arrived with the packaging secure. Installation was effortless thanks to compact battery size—just 0.64" in diameter and 1.91" long, which fit perfectly in my remote. I expect to get plenty of life out of these batteries as previous purchases have come with longevity and durability. If you need a dependable, non-rechargeable battery for specialty electronics, the A21 is an excellent choice. It’s maintenance-free, easy to install, and offers great value for the price. I’ll definitely be buying this battery again for my other devices that require unique specifications. Read more
