    Rechargeable AA batteries and such

    Howdy.

    I've used lots of AA rechargeable batteries.. more Lithium Ion lately.

    Who has experienced quick "fallout" of these batteries? Which are best in your experience/application?

    If by "fallout" you mean becoming unusable, I have. Actually I have given up on aftermarket batteries. Usually the original ones that came with the device worked great. Any replacements were about 1/2 the life-and I'm careful about charge cycles. Most any device requiring batteries I now lean towards the one you can substitute alkaline in. Gary

    For AA I've had best luck with Sanyo Eneloops. They are NiMH hybrid batteries that do not self discharge. A normal NiMH will be mostly dead after 6-8 weeks of sitting. The Eneloops will have 80% of their charge (or more) left after a full year of sitting. I've switched things like my camera stobe which isn't constantly in use to the Eneloops so there will be power when I need it. I've also some in AAA size for the headlamp that sits in my tank bag.

    The Lithium has a higher voltage than NiMH. That may be important for some uses. Also, I don't think the Eneloops come in a capacity larger than 2000 mAh. That may not be enough juice for your use.

    After years of using rechargeables, I have also given up on these. I buy Lithium for some equipment and Energizers batteries. The only rechargeable that I can count on are those that I use with my professional camera equipment.

    Lithium batteries are great in cold temperatures.

    Rechargeables

    I am with Marchyman on this - Eneloops. They hold their charge.
    The flashlight nerds over at the candlepowerforums.com are all gaga over them, too. I use them in any device that has to work after sitting for long periods (flashlights, for instance). I also use them in my digital cameras since they have a tendency to sit for extended periods of time.
    Ritz camera usually has them, and candlepower has links to order them.

    I gave up on AA and AAA rechargeable batteries years ago. This was mostly because they were one more thing to keep track of when I wasn't using them for a long period. For the money they cost and the amount I use them, I'd just as soon keep a supply of good quality lithium batteries handy. They have a shelf life of years, and I don't have to think about it.

    For touring purposes, they also mean I don't have to carry a charger, and replacements can be had at any drug store while on the road.

    I've been using Panasonic NiMH batteries for about 5 years.

    Although I have two batches of those batteries, the older ones when I conditioned them on a Cadex charger, came back to 90% capacity and they've been recharged countless times in 5 years.

    Whenever possible I try to buy devices that use AA batteries instead of proprietary batteries, otherwise you are carting numerous chargers along.

    Casio watch battery

    A little off the subject, but has anyone else experienced anything like this ?
    In 1989 when we got married, my wife gave me a Casio watch that according
    to the paperwork that came with it, had a 5 year battery in it. The strap on it
    broke more than 10 years ago and I put it in my dresser. Every 6 months or so, I
    look at it and can you believe that it is still running on the original battery ! It still
    has the correct date but is about 15 minuets fast.

    I have had the best all around luck with Energizer batteries. When I install them I usually write on them, with a Sharpie, the install date. A new twist that seems to be occurring is, for example, the flashlight going dim. Usually in what seems not enough on time for their use to be over. I have taken to testing each battery by itself and find one of the group has gone bad-less than 3/4 of a volt. I just replace one and I'm good to go. A good way to test them is with the Radio Shack meter #22-813. It's not a real precise meter but for quick all around use I can recommend it. HTH Gary
