What are the indications if a battery fails?

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?

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

Why might 'zero voltage' happen?

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