Recharge Batteries Using Solar Lights : No Electricity Required!
An AA battery is a standard size of battery. Batteries of this size are the most commonly used type of in portable electronic devices. An AA battery is composed of a single electrochemical cell. The exact terminal voltage and capacity of an AA size battery depends on the cell chemistry. But the power of a battery is limited. Charles Reyer, a normal human being uses the same AA battery unlimited times. He just uses solar power to charge his batteries. Check out his technique.
