"Piles" rechargeable actually delivered already loaded. I put them in the Wiimote controllers that are not used very often, hence the research reactors which discharge more slowly over a longer period between sessions. I was using previously Energizer Battery 2450 mAh I had to recharge every time. For now this is not the case with these Duracell 2000 mAh, we'll see if they meet their promise to use!
