Battery and Charger
• Unplug the charger from the electrical plug and the device when not in use.
• The battery can be charged and discharged hundreds of times before it eventually

replace the battery.
• 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.
• 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.
• 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.
