I have two sets of rechargeable batteries here at home. I used to charge them a lot when I was still using my Olympus camera which requires rechargeable batteries. That's one reason why, we bought the Sony digital camera. I am glad I have it though because we use it on our remote controls and my wireless mouse. There are different kinds of lithium batteries that you can find online. The two battery sets that I have has each own charger when we bought it.
