Because this is a 17" laptop, you will experience shorter run times than a similar 15 inch or 13 inch MacBook model. The large lighted display is the main drain on this battery. You can expect about 2-3 hours of run time with this computer battery when new, depending on your energy use. The higher capacity battery cells inside this cartridge have an energy capacity of 95 Whr.
