Battery safety
•  
Do not connect battery poles with conductors, such 
as keys, jewelry, or other metal materials. Doing so 
may short-circuit the battery and cause injuries or 
burns.
•  
Keep the battery away from excessive heat and 
direct sunlight. Do not place it on or in heating 
devices, such as microwave ovens, stoves, or 
radiators. Batteries may explode if overheated.
•  
Do not attempt to modify or remanufacture the 
battery, insert foreign objects into it, or immerse or 
expose it to water or other liquids. Doing so may lead 
to fire, explosion, or other hazards.
•  
If the battery leaks, ensure that the electrolyte does 
not make direct contact with your skins or eyes. If 
the electrolyte touches your skins or splashes into 
your eyes, immediately flush with clean water and 
consult a doctor.
