A battery shows signs of leaking and corrosion around its seams after a hard landing. What is the appropriate response?

• A.Stop using the battery and follow safe handling and disposal guidance for a damaged battery
• B.Wipe off the surface and return the battery to regular service
• C.Store it with the other flight batteries until it can be tested next month

Why

Leakage indicates the pack is damaged and potentially hazardous. It should be removed from service and isolated and disposed of safely rather than kept with serviceable batteries.
