All batteries need love and the BC-900 is a great way to show that you care. I'm constantly charging for my five digital door locks, flashlights, GPS and cordless mice. This charger has been one of my favorite devices not only for keeping my gadgets going, but for prolonging the life of my rechargeable AAs as well. It sports a display and charge-control modes for each battery. Find out more about what this device can teach you about your batteries after the jump.
