Performance and battery life can be severely affected if the battery gets too hot.
Do not use the battery in a location where static electricity and magnetic fields are
present, otherwise the safety devices may be damaged.
If the battery leaks and the electrolyte gets into the eyes, do not rub the eyes, instead,
rinse the eyes with clean water, and immediately seek medical attention.
If the battery gives off a strange odour, generates heat, becomes discoloured
or deformed,or in any way appears abnormal during use, recharging or storage,
 immediately remove it from the device or battery charger and stop using it.
