Each potato generates about 0.5 volts and 0.2 milliamperes. I connected groups of potatoes together in series to increase voltage and then connected these groups together in parallel to increase amperage. The entire 500 lb battery generated around 5 volts and 4 milliamperes.
How many potatoes equal a AA battery?
So one boiled potato would produce 5 volts of energy—the equivalent of about half the energy of an AA battery.
How powerful is a potato battery?
A couple years ago, researchers at the Hebrew University of Jerusalem released their finding that a potato boiled for eight minutes can make for a battery that produces ten times the power of a raw one.
How many potatoes would it take to replace the voltage from 1 AA battery?
I would just use one potato, at least for starters. If you want to get much current out of one of these batteries, you need to use lots of copper wire or sheet inserted in the potato, as well as lots of zinc-coated nails.
How many volts does a potato battery have?
You can read how much voltage you have available in this potato battery. It reads . 85 volts, not bad but not enough to do anything fun.
