Rechargable AA’s. What’s better than NiMH?

cam.pngbattery2.gifYou have one of the digital still cameras that uses rechargeable AA batteries because, in a pinch, you can always go buy some Alkalne batteries at the store and take a few more pics. This works around the world. I know because I was stuck in Germany without a way to recharge the AA’s I had there.

So we bought a set of four Alkalines. And then another. And then another. Etc. Given the cost of those things in Germany, it wold have been a helluva lot smarter to just go and by a AA recharger with batteries the first time, but we didn’t think Alkalines would die so quick. Then the problem was that we’re in a small town nowhere near a decent electronics store- but the gas station is right down the street. Being able to use Alkaline batteries enabled me to document this international trip.

Trouble is, when you’re not using it, you put the camera on the shelf, or in the drawer. Then, when you see something that would make a great picture, you run to get the camera, turn it on and it says “Change the batteries.”

How do they die so darn fast when they’re not doing anything?

It turns out that all batteries loose their charge just sitting around. Rechargeable batteries are the worst.
Now, there’s been a small undercurrent of “new” NiMH batteries that tout longer shelf life. Eneloop is one brand, but there are a few others. To do some tests, I bought one such brand, and a new charger that came with some new traditional NiMH batteries. I also have a few sets of older rechargeable NiMH batteries. I charged them all, and let them sit in little plastic cases for months.

Then I put them in the camera and tried to take pictures. Let me tell you what happened… Read more…
