There's been a lot of press in recent years about how to recycle old batteries, but in some areas it's just not easy. So instead of going through packs of batteries, recharging might be the way to go.

Rechargeable batteries isn't a new idea, but this kit does make it pretty easy. Made by Sanyo, the eneloop Rechargeable Battery Kit contains AA, AAA and C and D adapters. And the USB Rechargeable Travel Kit allows you to charge your batteries using your laptop for energy. Not bad for frequent travelers. They supposedly retain their power for up to a year.

Similarly, Duracell offers rechargeable batteries that use a wall of car outlet, as well as a USB port. Its Mobile Charger will also be able to recharge devices like iPods and Blackberrys. And they're a little cheaper than the Sanyo selections.
