The standard bearer for rechargeable NiMH AA's.
The eneloop AA's have been around awhile and have weathered the storm of competitors with huge mAH ratings in comparison by simply demolishing them in one category; longevity of charge. I've had rechargeable AA batteries for use at work and home for years now and the most frustrating thing is loading up a pair out of a drawer and they are dead or near dead. Sanyo has that solved and in doing so has made me phase out all of my other brands in favor of the eneloops. These are the new Rev A version that supposedly have a longer lifespan due to being able to handle more charging cycles but I haven't managed to wear out the old version yet! I use quality chargers like LaCrosse and Maha's that charge each cell individually. I also have enough batteries now that I can afford the time necessary to slow-charge them instead of the 1-hr quick charge cycles that are infamous for reducing lifespan.<br /><br />I really can't emphasize enough the importance of knowing when you turn a device on that the battery inside still has juice in it! Same goes for having batteries stored up for a rainy day. Having a storm sneak up and knock the power out but having ample battery life on tap from batteries charged over a year ago is good peace of mind.
