A lot of people carry extra batteries with them in case of power shortage on their device, but sometimes get confused between charged batteries and uncharged ones, and dont know which one to replace the dead batteries. We designed a smart battery that can be distinguished by the colors of the charged and uncharged batteries, making it easier for users to find the ones ready to use.
