Battery Care 

• Your device is powered by a rechargeable battery. When the power 
is weak, please charge the battery. In order to extend the lifespan of 
the battery, use all the battery's power before recharging. 
• Unplug the charger from the electrical plug and the device when not 
in use. Do not leave the battery connected to a charger more than a 
week. Overcharging may shorten its lifespan. 
• Extreme temperatures can affect the ability of your battery to 
charge. Battery needs the fit temperature. If the surrounding 
temperature is over 40°C, the battery cannot be charged. 
• Use the battery only for its intended purpose. Never use any charger 
or battery that is damaged. 

Do not short-circuit the battery. Accidental short-circuiting can occur
