Battery security
● Please use the original battery. The warranty will be invalid by using any other accessory. The manufacturer will
not take any responsibility for any damage caused by not using the original battery.
● The new battery can realize the optimal performance after fully- charging for 2 or 3 times.
● The battery can be used for hundreds of times, yet it will wear out eventually. When its talking time and standby
time shrinks sharply, you need a new one.
● Cut off power supply when not using the charger. Don’t charge the battery for more than one week, since over
charging will reduce its using time.
● Do not short-circuit the battery with metal stuff (such as the key in your pocket)
● Do not bend or open the battery.
● Do not put the battery into water or fire.
● The battery should never be charged at temperature below 0 degrees or above 45 degrees Celsius.
