Homemade water battery. how to make a battery using water. produces free electricity. this “earth battery” is made with 3 items (metal screws, copper wire, a container) powerful 1.5 volts to 12 volts and more. runs lights, clocks, calculators, timers, digital thermometers and almost anything that runs on button cell batteries. hook a couple together and you can run small fans and radios. use lemon juice, lime juice, saltwater, vinegar or bleach to increase the amps. using more copper will increase the amps too
