High Capacity Replacement battery.
Each Superb Choice battery was tested at an original laptop by the manufacturer.
If your original battery is a 6-cell battery, this 9-cell battery has much higher capacity and works longer hours after each charge. However, it is bigger, heavier and sticks out due to the extra 3 cells. It will still fit in your laptop.
