I don't know about the green ones but I believe that (IMHO) that AW's red are good solid batteries that last. Friends have tried cheaper batteries and had cheap results. That said, maybe the green ones are great. Might want to test them on a charger and see how long they hold a charge. I date mine (tiny sticker), use in rotation and when they loose a charge quickly, drop below a certain level, or are around for more than a year, they are recycled and I get new ones.
