During setup, a battery is found to be swollen and puffy, although it still powers the aircraft normally. What should the crew do?

• A.Remove that battery from service and do not fly with it
• B.Fly a shorter mission so the battery is stressed less
• C.Squeeze the battery back to shape and charge it fully

Why

Swelling signals internal damage in a lithium battery and a higher risk of failure or fire. A battery in that condition should not be flown, even if it appears to work normally on the ground.
