Hello! does anyone know if there is a way to make them last for longer? if i am correct the only reason they stop working is because the electrolyte evaporates? so is there such thing as an electrolyte that is solid/longer lasting?
Hi, I'm wondering if anyone knows, if we can make batteries out of coins, why dont we do we even have normal batteries? could one make a battery that would power a lamp, lets say, out of pennies? How long would it last?
