I have had these batteries for a while now, maybe for a little over two or three years now, and I can honestly say that they are really fantastic. I bought maybe three packs of these, since double AA are the most common batteries needed in my house, and they are really handy. I use them for my television remotes, for gaming console controls, and I even have some left over in case I lose any of them. They are quick to charge and normally I can place them charging somewhere over-night and they are good to go in the morning for use again. They were pre-charged when I first got them, which saved me the hassle of immediately having to put them to charge when I first got home. Not only that, but the battery last for a very long time. Energizer was a brand I had already trusted from previous battery buys, although those were not re-chargeable, and somehow I knew these were gonna be reliable. Honestly, these batteries are the only ones I would recommend to buy.
