I KNEW it had to exist somewhere.

For automotive - Strings = Battery (a battery is a string of cells)

Nice article.

However, I think the author "lost it" in his last few paragraphs, and I'd like to see more information. How good is your research technique?

Perhaps it's a simplification, but I don't see how one (healthy) lead-acid cell can recharge another (healthy) lead-acid cell. (The scenario with two strings and one shorted cell is different - I agree with that.)

It's a chemical process. During discharge, one reaction is happening and electrical energy is released.

During recharge, electrical energy is used to reverse the chemical reaction (electrical energy is "stored" chemically in the cell.)

If the normal discharge reaction is reversed (the cell is "recharged") by applying a higher voltage than the discharge reaction generates, how can the discharge reaction in one cell produce a large enough voltage to reverse the SAME reaction in another cell?

It's like releasing a ball to roll down a small hill under gravity, and expecting it to roll to the top of a taller hill. It just doesn't work.

Am I missing something?

I have another one coming from the current head of the IEC Secondary (rechargeable) battery committe. Should have it next week. Same topic.
