Remotes, keyboards, and mice are just a few of the battery powered items I use on a daily basis. Before I started using rechargeables, it was a pain when something needed a battery. Even though I would buy the large packs at the store, it seemed I was always out of the size I needed. Then I found Tenergy. They had the whole kit for me, and the batteries were already to go once I received them. I have had them for about 3 years now and what a relief. They have batteries for almost everything. Give them a try.
