This is an aluminum and copper battery that uses salt water and few droppers of household hydrogen peroxide. It makes more electricity than about 1,000 lemon batteries. It can power an LED to shine brightly. With 8 of these battery cells you could recharge a cell phone or run a radio for several days. To recharge the battery, simply add another dropper of hydrogen peroxide to each cell.
