If the battery fluid gets into eyes, do not rub your eyes.
Otherwise, your eyes can be hurt. Wash with clean water
and go to see a doctor immediately.
If there is battery deformation, color change or abnormal
heating while you charge or store the battery, take it out
immediately and stop using it. Otherwise, battery leakage,
overheat, explosion, or fire may occur.
When installing the battery, do not push the battery by force
lest battery fluid leak out or the battery crack.
Do not take out the battery when the phone is turned on.
If you do not use the battery for a long time, store it in normal
temperature after charging.
Charger
Use the charger approved by the phone manufacturer only.
Any violation of this rule may result in fire or malfunction of
the charger.
Do not short-circuit the charger. Short-circuiting the charger
may cause fire or malfunction of the charger.
If the power cord is damaged (for example, the lead is
exposed or broken), or the plug becomes loose, stop using
the cable at once. Otherwise, electric shock, short-circuit of
the charger, or fire may occur.
Keep the charger dry. Once water or other liquid leaks into
the charger, electrical leakage or other faults may occur.
Do not use the charger in a dusty and damp environment.
Keep the power cord away from any heating appliance.
Ensure the charger is properly plugged into the power
socket properly when charging the battery. Improper
insertion may result in electric shock, fire, or explosion. To
unplug the charger, pull the plug off rather than tear the
power cord.
