liquids. Doing so may lead to fire, explosion, or other hazards.
•
If the battery leaks, ensure that the electrolyte does not make contact with your skin or eyes. If
contact is made, immediately flush with clean water and consult a doctor.
•
If battery deformation occurs, it changes colour, or it overheats while charging or storing, stop
using the device immediately and remove the battery. Continued use may lead to battery
leakage, fire, or explosion.
•
