
Otherwise, it may lead to electrolyte leakage, overheating, fire,
or explosion.
If battery electrolyte leaks out, ensure that the electrolyte does

not touch your skin and eyes. If the electrolyte touches your skin
or splashes into your eyes, wash your eyes with clean water
immediately and consult a doctor.
If there is a case of battery deformation, color change, or

abnormal heating while you charge or store the battery, remove
the battery immediately and stop using it. Otherwise, it may
lead to battery leakage, overheating, explosion, or fire.
If the power cable is damaged (for example, the cord is exposed

or broken), or the plug loosens, stop using the cable at once.
Otherwise, it may lead to an electric shock, a short circuit of the
charger, or a fire.
Do not dispose of batteries in fire as they may explode. Batteries

may also explode if damaged.
