How can you tell if a battery is good or bad?

First check for defects like broken circuits, shorts, or broken containers. If no outward problems, check capacity using known measuring techniques.

Why might 'zero voltage' happen?

Zero voltage indicates a broken circuit, possibly due to broken electrode columns, partition welding defects, or terminal welding defects.
