Battery Boasts USB Rechargeability

The batteries, which recharge by plugging into a USB port, are already for sale in the United Kingdom and will be available soon in the United States.
U.K.-based Moixa Energy Holdings Ltd. has launched a USB-rechargeable battery, the USBCell.

The AA battery opens to reveal a USB connector. It can be plugged into any PC USB port to charge. The batteries are already for sale in the United Kingdom, two for about $24, and will go on sale soon in the United States.

When you plug them into the USB port, a light around the rim means they're charging. A slow flashing light indicates they're 90 percent charged. The batteries are ready when the light shuts off. Each takes five hours to charge.

AAA batteries, 9-volt, and lithium-ion batteries will follow shortly, the company said. Moixa Energy also will release USB-rechargeable cellular phone batteries.

Moixa Energy launched the batteries at DEMOfall 2006 in San Diego, Calif., earlier this week.
