very good batteries and cheap
Hi, I needed some new batteries for my ceiling fan remote and was going to get the while I was in a hardware store. But then I realized they were selling them for almost $11, and Walmart had them for only $5. Ordered them and arrived the next day and saved a lot of money.

Duracell still remains the top battery in my household. They last forever in everything from remotes to scales. Sure they are a little more money but worth every penny! I have even experienced them lasting new in larger packages (that I unfortunately misplaced) working well BEYOND the expiration dates. As with any battery I have occasionally experienced leakage but these incidents are very few and far between. Will continue to remain loyal to this brand.

Dependable - reliable.
Dependable! This is my 'goto' brand when I want and need dependability! I use this battery to power my remote controls to turn on/off my table lamps next to my bedside - I can turn on the bedroom lamp from another room using a remote activation module which I purchased thru Walmart online. the remote uses 12volt battery which my local stores don't carry.
