USB Rechargeable AA Battery

Take a look at these rechargeable batteries. It is the 1450mAh AA size rechargeable batteries that can be charged via USB. When low-batt, just open up the cap and insert it to the USB port for charging, a blue light will appear to indicate that it is charging and will turn off when it is fully charged. More pictures after the break. The USB rechargeable AA battery is available for $20.40 each. Alright, I’m okay with the normal rechargeable batteries.
