䢇 Use the AC power supply defined in the specifications of the
charger. An improper power voltage may cause a fire or a
malfunction of the charger.
䢇 Don’t use the battery charger in direct sunlight or in high
humidity areas, such as the bathroom.
䢇 Unplug the charger from the electrical plug and the device
when not in use.
䢇 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.
䢇 Never dispose of the battery by incineration.
䢇 Keep the metal contacts on top of the battery clean.
䢇 Do not connect two poles of the battery with conductors,
such as metal materials, keys, or jewelries. Otherwise, the
battery may be shortcircuited and may cause injuries and
burns on your body. Don’t attempt to disassemble or short-
circuit the battery.
䢇 Avoid dropping the device or battery. If the device or battery
is dropped, especially on a hard surface, and the user
suspects damage, take it to a qualified service center for
inspection.
䢇 Do not modify or remanufacture, attempt to insert foreign
objects into the battery, immerse or expose to water or other
liquids, expose to fire, as any damage to the battery may
result in a fire, explosion or other hazard.
䢇 Do not disassemble the battery or solder the battery poles.
Otherwise, it may lead to electrolyte leakage, overheating,
fire, or explosion.
䢇 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.
䢇 The battery may need recharging if it has not been used for
a long period of time.
䢇 It’s best to replace the battery when it no longer provides
acceptable performance. It can be recharged hundreds of
times before it needs replacing. Danger of explosion if
battery is incorrectly replaced.
䢇 New batteries or batteries stored for a long time may take
more time to charge. When charging your battery, keep it
near room temperature. When storing your battery, keep it
uncharged in a cool, dark, dry place. Some batteries perform
best after several full charge and discharge cycles.
䢇 Don’t store the battery in high temperature areas for long
periods of time. It’s best to follow these storage rules:
䡲 Less than one month: -4° F to 140° F (-20° C to 60° C)
䡲 Less than three month: -4° F to 104° F (-20° C to 40° C)
䡲 Less than one year: -4° F to 68° F (-20° C to 20° C)
