Using Tips:
1.We recommend that you open the back cover of your laptop to check your original battery model and appearance before placing an order, especially the position of the connector and the length of cable.
2.Please check the interface to make sure it's clean enough before installing new battery.
3.Please discharge the new battery to 5% (not 0%), then charge fully and cycle 3-4 times to wake up the new battery.
