Review on Duracell Rechargeable AA Batteries - Long Lasting, Multipurpose Double A Battery for Home and Business Use - Pack of 4 by Richard Cheng

UPDATE: I have used these batteries again, charged them fully and they have lasted longer than I needed. I don't know yet how long they will last without a break, but I like that they really work and are free from imperfections. Now I will charge them before using them for my camera flash. My only concern is the fact that if their batteries didn't work neither Amazon nor Duracel would do anything about it, so I guess they don't care about the bad reviews. Anyway, that's all goodbye. FIRST CHECK My return window for returning these items is closing before I can finally use them. I've been using them for my camera flash since I've been photographing weddings. Batteries died before the first hour was up. I have used Rayovac before and they have given me two full 5 hour events. They died before the first hour had passed. I switch them to a second pair of four batteries and they also ran for about an hour and a half. I'm really disappointed with these batteries. I will try to recharge and use them again. (Note: I fully charged all 8 of these batteries and they all failed to survive a full event). I switched to them, I didn't want to buy disposable batteries all the time. I am really disappointed.
