Discolor Battery / Battery

Discolor Battery
Discolor Battery

We often retained a lot of batteries at home. These batteries mixed together, so that it is difficult to determine which battery still can be used. This design added materials which can change color according to induce the amount of charge to the outer layer of the battery. With the reduction in battery power, the color of the battery faded, and eventually it turn white. We can know the battery’s power, by the color of the battery.
