Weird Asian News reports these as "pee-powered" batteries, though I can't see anywhere on the packaging the sign saying you HAVE to pee in them. "To use you just have to put water in" it says. It's nice idea, but they're only intended for use in small radios and LED lights.
Another fantastic Japan-only item.
