dell precision mobile workstation m6400 laptop battery have two main ratings on them: Volt and Capacity. Please compare with your notebook computer battery's capacity, for example, 8800mAh laptop battery may have double runningtime than 4400mAh battery(actual running time may different depending on the program running on your laptop).
dell precision mobile workstation m6400 Batteries are also rated by Watt-Hours, perhaps the simplest rating of all. This is found by multiplying the Volt and the Capacity together.
For example: this dell precision mobile workstation m6400 laptop battery 10.8 Volts, 85WH (Note: 4400mAh is equal to 4.4 Amperes, 6600mAh is equal to 6.6 Amperes, 7200mAh is equal to 7.2 Amperes, 8800mAh is equal to 8.8 Amperes Etc.)
10.8 x 0.085 = 0.918 Watt-Hours (Watt-Hours)
Watt-Hours signifies the energy needed to power one watt for one hour. This dell precision mobile workstation m6400 battery can power 0.918 watts for one hour.
The higher the mAh rating, the longer the battery will hold its charge between charging cycles. An mAh rating larger or smaller than your original battery's will have no impact on the performance of your laptop computer.
