This isn’t your ordinary AA battery. Called the USB Cell, it’s a clever little device. Inside, it’s a rechargeable Ni-MH battery. However, to recharge the USB Cell, you simply plug them into an USB port. The top green part of the batteries can be flipped over to reveal the USB plug. Recommended charging time is 5 hours via USB or 7 hours in an approved 250 mA Ni-MH charger. The product page claims that these Ni-MH batteries provide 10-25% greater capacity than NiCD batteries.

Get the USB Cell for £12.95 ($26) at I Want One Of Those.
