As far as runtime goes for our BG 15-21-130 these battery's capacity is 130Wh(Watt-hour). You can compare these battery's capacity with your internal battery capacity to figure out how long this battery can run your notebook. For example, if your notebook internal battery output is: 10.8V & 4000 mAh, then, your notebook internal battery capacity is: 10.8V x 4000 mAh = 43200 mVAh= 43.2 Wh (Watt-hour). This external battery capacity is about 130/43.2=3 times of your internal battery capacity. If your internal notebook battery can run 3 hours, then the external battery pack can theoretically run about : 3 hours x 3 = 9 hours. This is a rough estimate. Actual running time varies, depending on notebook computer's configurations and what kind of applications running . For example, screen brightness, the use of the CPU, the hard drive, the CD drive, and other peripherals results in an additional drain upon the battery, effectively reducing the battery's run-time. The total run-time of the battery is also heavily dependent upon the design of the notebook. To ensure maximum performance of the battery, optimize the computer's power management features.
