This item is brand new but the package has been opened. It will ship the generic box as the box was severely damaged so I replaced it with a brand new box.
Please open the back cover of the laptop before ordering and make sure that the original battery model is consistent with the listing. After getting the battery please install the battery correctly make sure the battery connector is firmly connected to the laptop motherboard and use the original charger to charge the laptop. Discharge the new battery to 5%, not 0%, then charge and recycle 3-95 times to wake up the new battery
