Next Gen Oxyride Batteries Coming Soon
marksilverman writes "The New York Times is reporting that Panasonic will start selling (Biometric scan required to prove your value as a human being) next generation Oxyride batteries soon. They last twice as long as premium alkaline batteries, they deliver more power, and they're cheaper. They're already popular in Japan. The downside? They have a shorter life in a "rundown test" where you put the batteries in and leave the power on until they're drained. In real-world scenarios (like how many digital pictures you can take) they do really well."

Did you read just a little further down? The article mentions that these batteries put out 1.7V vs. 1.5V for a regular alkaline.
NiMH batteries don't have a charge memory; you're thinking of NiCads. Plus, the best NiMH batteries store almost as much energy as alkalines, and in AA format they're not too expensive due to volume and competition.
Li-ion, on the other hand, is a very expensive format due to the need for internal circuitry to protect the battery, and as a result it doesn't come in the standard sizes, which can guarantee a high cost as each manufacturer can rip you off for their own format...
For many many applications, NiMH is by far the best way to go.
