Stop using the device
Power down and avoid touching leaked material with bare skin. Keep the area away from children and pets.
Follow product guidance
Battery chemistries use different electrolytes. Use the manufacturer’s cleanup and disposal instructions rather than improvising a neutralizer.
Inspect before reuse
Corroded contacts, swelling, heat or damaged insulation can require qualified service or device replacement.
Decision boundary
This guide narrows a battery decision but does not override the device manufacturer’s current manual or safety instructions.
