Terry Knight's video: Lightors Batteries Recharge Through Built-In Micro USB

Lightors are rechargeable batteries, which is not amazingly new technology however these rechargeable batteries eliminate the need for a wall charger. The batteries are designed around the double-A and triple-A form factors and contain a nickel-hydride battery that is charged through a micro USB connection built into the cell. The double-A cell has a 1500 milliamp-hour charge capacity, 600 for the triple-A, which is about equal to most general purpose batteries or about half that of an alkaline battery. There are several factors that affect the life of a rechargeable battery, and Lightors estimates that these batteries will be good for five hundred charges. Check them out: http://www.lightors.com/
