About batteries:

  • How about the battery’s lasting or working time?
    Actually battery’s run-time is dependent on the device's total power consumption rate.
    It related to following factors:
    ●the speed of the laptop’s processor
    ●the amount of application software
    ●the number of wireless interface devices
    ●the brightness of the screen
    ●the amount of cycle that you’re using it for
  • How to maintain battery life?
    We suggest that you do the battery activation at least once every two months, as it will extend the working time and life of your battery.
     If you won’t the battery for a month or longer, we suggest you charge the battery to 50%-80% capacity and then remove it from the laptop. Store it in a clean, dry place until you need it again.
  • How long is the battery life?
    Our battery was tested and checked well before shipment. Under the normal using condition,the life of the lithium battery is about 500 time of cycles, so that usually as far as possible to use the fast end (5-7%) in charge, the average use time is 2 to 3 years.
