What action should be taken if a battery shows signs of swelling or leakage?

• A. Continue using with caution.
• B. Isolate the battery, tag as unserviceable, and follow disposal or replacement procedures.
• C. Charge it to full to see if issue resolves.
• D. Ignore and monitor without action.

Answer: (B)

Swollen or leaking batteries are damaged and can vent hazardous gases or ignite. The priority is safety and preventing a bigger hazard. The proper action is to isolate the battery from all equipment and personnel, tag it as unserviceable, and follow your established disposal or replacement procedures. Do not charge, use, or continue to operate the system with the suspect battery. Handle it with appropriate precautions, place it in a nonconductive, fire-safe container, and route it through approved disposal channels. This approach stops the risk and ensures the device is repaired or replaced safely.
