Yes, the screws on the bottom expose the battery pack. The problem is where to find this particular battery pack. It is a 6 cell blue plastic wrap: ICR 18650 4400mAh 11.1V 48 . 84Wh
It has a red and black wire on it that clips into the mother board. Pretty easy swap if the battery pack can be found. The only place to purchase seems to be wholesalers with large quantity orders.
