I ended batteries when my mouse and remotes started losing power. So i went with these based on price. They are really good batteries and I like them a lot. I really like that they are wrapped every 5 batteries so you don't have open batteries sitting in a drawer. I did this with a huge thing of larger batteries in the same junk drawer and they all had dried battery acid all over the tips. I am not sure why but I guess they are all ruined from being exposed. So i am glad when I saw that they are shipped protected in sets. No problems, have had them for a month and like them a lot.
