ABSTRACT
Bio-battery is an eco-friendly battery which made of natural ingredients, such as banana peel and lemon peel. Banana peel contain Potassium chloride, magnesium, and zinc, which allow it to conduct electricity. Lemon peel, on the other hand, contains citric acid, which also enable to conducts electricity. Furthermore, creating bio-battery is as simple as emptying a used battery and replacing it with banana peel paste and small pieces of lemon peel in two different battery tubes. Both bio-batteries have 1,1volts. The lemon peel bio-battery produces a dimmer incandescent lamp than the banana peel bio-battery. To sum up, bio-battery is useful for reducing waste in addition to conducting electricity, especially battery waste, banana peel and lemon peel waste.
