Energizer's Next Gen Zinc Air Batteries to Triple Run Time

The technology for Energizer's Zinc Air batteries may go back 35 years, but it's certainly being used well. These new batteries, which we'll see this summer, will be smaller and have three times the run time of prior versions.

The downside of these batteries is that they're not rechargeable, but they're still smaller than other standard batteries and will be great for newer, tinier gadgets. [Tech On via Engadget]
