Panasonic’s EVOLTA Robot Uses 12-AA Batteries to Travel 317 Miles [Video]

Considering it is the day after Thanksgiving, how about a little publicity stunt from Panasonic to tide you over during your extended weekend? Even if batteries are one of the most commonly used items in the world, it seems Panasonic doesn't think they get enough attention. That's why they put together the EVOLTA robot, and decided to send the little robot on a 500-kilometer trek across Japan.

Microsoft InstaLoad Batteries Don’t Depend on Polarity

Have you ever had your power go out in the middle of the night, whether due to electrical issues or a natural disaster, and found that putting a new pair of batteries into your flashlight is a remarkably frustrating ordeal, due to the fact those batteries have to be inserted in one particular way for the flashlight to work.

Horizon MiniPak Brings Hydrogen Fuel Cells to the Masses

Horizon MiniPak Brings Hydrogen Fuel Cells to the Masses

We're all looking for alternate, better, and more powerful ways to charge all of our gadgets. That's half the fun of owning all these shiny things: finding ways to actually keep them powered. And while double-A batteries, or any of their brethren, work great for some things, and those AC wall chargers are constantly plugged in, we're always in the market for something that we can take with us, doesn't kill our batteries in the process of charging, and can last longer than we probably need it to. That's why we're happy to hear about the Horizon MiniPak.

Energizer ‘D’ rechargeable battery cracked open: cheaper, low-power AA lurks inside

Energizer ‘D’ rechargeable battery cracked open: cheaper, low-power AA lurks inside

For most people, a battery is a mysterious little pack of magic, containing the juice that makes our gadgets flash and bleep (and then run out just when we really need them).  For Energizer, it seems, batteries are an opportunity to perform some mild deception: it turns out that inside the chunky, D-sized casing of an Energizer rechargeable is a spacer-clad sub-C cell AA battery offering far less power than you'd expect.

Update: Commenter huskyboy1978 points out that's not an AA battery, but a production-sized sub-C cell.
