Penny and Nickel Battery

Step 5 Troubleshooting

If your battery does not make any voltage, check the following:

1)Make sure the coins are stacked in an orderly fashion. Make it as upright as possible.
2)If your multimeter does not show any number, do #1, and also try switching the multimeter leads around.
3)Taste the paper to make sure it is quite salty.
4)Make sure the pieces of paper are not touching eachother.
5)Add more coins! If you don't see much voltage, just add ore and more coins to get it to a good amount of voltage.

how long do they tend to last

Until the juice dries up, however long that takes.

You can make them last even longer if you seal them in plastic wrap or large shrink wrap to keep the moisture from evaporating so quickly. Just a thought.
