Warnings and Precautions  
• Do not connect two poles of the battery with conductors, such as metal materials, 
keys, or jewelries. Otherwise, the battery may be short-circuited and may cause 
injuries and burns on your body.
• Do not disassemble the battery or solder the battery poles. 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. When 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.
Cleaning and Maintenance

the charger with a wet hand. Otherwise, it may lead to a short circuit, a malfunction 
of the device, and an electric shock to the user.
• Do not place your device, battery, and charger in places where they can get 
damaged because of collision. Otherwise, it may lead to battery leakage, device 
malfunction, overheating, fire, or explosion.
