If a battery fails, what are the indications?

Indications include lower performance, low voltage, inability to charge/recharge, swelled container, and acid corrosion.

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 exist, 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.
