Reliable batteries!

I needed this size and was glad Walmart carried it. I ordered and it was here the same day! Energizer is a brand I use for those devices that don't get used much in my house, but that I know will last quite a while and be ready when I do need to use them!

I purchased these for light/fan remote controls. They have a long battery life. I recommend these batteries.
