Dry Cells? How do they work?

[Painless]

My two flat round monetary units on this:

Some leakage of current will occur because of the holes, however, the current is leaking into the next cell where it can be applied to production. There will still be some loss in the flow back up to the reservoir, however, this path will have an extremely high resistance which will dissuade electrons from taking this path.

As for the top and bottom vs just top hole scenario, I personally feel that the top only hole design is opening you up to the possibility of trapped air pockets in the cells which will hinder surface area for production.

The term dry cell comes from having all your electrical connections outside the cell so there is no chance of a short or arc in the cell causing an explosion.
