The NI-MN AA Panasonic Enelope Pro mentioned above, are the most used and recommended AA battery for cameras by the photo fans. I have had several for at least 10 years and they are very good, much better than other brands I have.
Recently, after 10 years or more, a couple of mine have only been holding the charge for a few weeks and when new, they held charge for many months. I use an old time charger and I often leave then on for many hours probably contributing to there deterioration.
