Beer and Urine Make 'NoPoPo' Batteries Last 10 Years
Leave it to our clever, if bizarre, Japanese friends to come up with the NoPoPo battery.
According to Unplggd, the battery gets power when one of several fluids mixes together with its magnesium and carbon components. Among those fluids are beer, saliva and -- that's right -- urine.
Apparently, those unlikely charging agents help the batteries to live for as long as ten years. And the bizarre charging method is much simpler and more sanitary than you'd guess. All you need is a cup, the batteries and the included eyedropper. You can, we're sure, figure out where to go from there.
Even if these AAA and AA batteries wind up being less than satisfactory, the novelty itself is well worth the $15. [From: Unplggd]

What do you do when it, like all batteries, starts to leak? Diapers? I love Japan!

That 10 years is the shelflife, right? I mean, if a battery keeps going for 10 years, that would be a major technological breakthru. It's almost like a baby reactor. A long shelflife is important in itself, however. My biggest question is, does it recharge if you add more urine or beer...and if you use the urine, can you use the beer next time?
---------------------------------------
Just a little interesting knowledge here I learned when in the Philippines: Did you know if a regular battery (not rechargeable) is very weak, not dead, you can boil it in hot water for 2-3 minutes...and you'll get about another 1/2 to 1 hour of full power? It loosens up and excites the electrolites. This is lifesaving knowledge in an emergency. Perhaps auto companies could cook their batteries by thermally insulating them to squeeze more mileage out of an electric?
Anyway...high 5's to Japan; that's quite an achievement!

Unfortunately, the amount of energy used to boil one 100mL (about half a cup) of water, ~33,000 Joules, is significantly more than the entire capacity of a brand new alkaline AA battery (about 5,000 Joules) much less the little tiny bit of extra runtime you get from the boil. I suppose in an emergency if you needed to use a radio or something, it could prove useful.

I KNOW boiling an AA battery or AAA for 3 minutes sounds dumb and
wasteful...but in some 3rd world countries...a battery store isn''t
always around the corner, or if you are deep in the woods. The joules
wasted are not even in the equation if it's an emergency. The idea is
to USE the battery because you don't have a replacement.
BTW - if you have a magnifying glass (with rotation and a glove) and
a bright sun, or a small torch, you might get similar but not as
efficient results. Peeling the label 1st is advised to avoid embers.
Natch, a red hot battery will not only will ruin the device, but the
electrolites inside may dry and clot, rendering your experiment into
overkill. Boiling is your 1st choice. Why 2-3 minutes? Just long
enough to HEAT the battery, not render it soggy or spring a leak.
What if you don't HAVE a good battery at all...and you're out in the
bush??? Look for citrus fruit or acidics...either in your supplies or on a tree if in a warm climate. A simple lemon can output 1.5 volts with the
right bi metal electrodes. The very best is the grapefruit, with high
acid content. Milliamps are as good as any AA battery. Also try starch, like in potatos or carrots, and salt water.

I used to stick my gameboy batteries in the sun to get a bit more charge on roadtrips. I live in california so it gets pretty how with just that.

I think I saw this on Manswers (on Spike TV) not too long ago.
I'd buy a couple.
