I was waiting for these dang things to finally wear down to the point I had to recharge them so I could let everyone know how long they last. I thought I might die first, it took forever compared to regular AA's. I've got a canon a75 and the regular AA's that came with it lasted about 1 1/2 days with me messing around trying to learn the camera. Everyone suggested rechargeables. I was at Wal Mart doing some Christmas shopping with my wife and found an Energizer 15 minute charger with four 2200 Mah batteries for about 28 bucks. I bought it for myself that day, charged them that evening and have been playing with the camera for the last week and a half or more and they finally went out today. I've taken pics around the house, pics of my wifes new cat as well as used the video mode for about 5 minutes of video at my sons Christmas program the other day. I just thought I'd pass it on for anyone looking for a very handy charger with incredible batteries for your digital camera. And I love it that they only take 15 minutes to charge. Cya'll, Greg
