I've got one of those Energizer battery chargers that plugs directly into the wall, kinda like those room deodorizer plug-ins. No cords getting in the way, it takes 2-4 AA batteries at a time. Think I paid about $30 for the charger and with 4 batteries. The Energizer rechargeable batteries seem to last at least twice as long as the disposable ones before I have to change them out for recharged ones. My camera takes 4 AA's, and I always have four new ones ready for immediate back up.
Sure beats the heck out of buying big blocks of batteries at Sam's Club! You'll be wondering why you didn't do it sooner.
Radio Shack used to sell a charger that would charge any size from AA to D. I used it for years till it died. Seems as if it was around 20-25 bucks. If they still make it is a was a good one. A bit bulky though if you only need AAs charged.
Also speaking of batteries. If you have a Big Lots nearby check their battery prices. I buy a 4 pack of Fuji Alkaline AA for $1.49!! I go in and buy 6-10 packs at a time. 2 D's are 1.49 and a 9 volt is the same price. I use them exclusivly now.
I buy out batteries for Church there now. We gave up on recharging because these are so cheap. And there good batteries. I have only had a couple that didn't last but a short time.
I have a Kodack Dc215. The only ones I found that lasted more than a few trips were the Kodak ones that they recommend and their charger. It is worth its weight in gold and lasts 10 times longer than any other I tried. I used one set of batteries, with recharging that lasted over 2 years. I have since bought another set with that has now been recharged and used for a year. I can't even begin to tell you how long they last. The best thing about them is, when it shows that the battery is low.....you have at least 15-20 pictures left before it gives out. All of the other "rechargeable batteries" once it showed that they were low....they died!
So, even if you don't have a Kodak Camera, you might want to consider their battiers (they are AA) and their recharger.
