Lemon and potato batteries

How long do potato batteries last? How long do lemon batteries last?

Hi,

Potatoes and lemons contain electrolytes that transport ions in the battery. The battery also needs electrodes, usually zinc and copper. Potato and lemon batteries will last as long as the electrolytes are present and the electrodes are intact. The battery won't work if the potato or lemon dries out or if an electrode dissolves.

You might want to take a look at the project described here:

The background section describes how a potato battery works and there is a list of references that may be of interest to you.

I hope this helps. Please ask again if you have more questions.
