This battery is going to be LARGER than the original battery and will protrude to the rear of the laptop but will not be noticed when the screen is open, it will still snap into your computer and power it up. The added run time is achieved with an additional 3 cells inside the cartridge. Users of this battery pack experience an additional 1-2 hours of run time over the standard battery. Estimated run time with this battery is 3-5 hours. Longer run times can be achieved by minimizing the power use, especially the screen brightness.
