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

Check for defects like broken circuits, shorts, or broken containers. If no outward issues, check capacity using measuring techniques.

Why might 'zero voltage' occur?

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