Compaq NC6400 Battery
Your Compaq NC6400 battery allows you to move freely about so as to work or play inside, outside or anywhere your heart desires. Buying a battery with a higher milliamp rating is fine, it simply means it is a stronger battery. What really is critical to a battery fitting your laptop is the actual size of the battery and the connection it has. Not all batteries are the same, make sure and double-check the model number and compare it to the old battery. More amps in a battery basically means the longer you will be able to use the laptop when fully charged.

- The unit does not turn on while not connected to the AC adapter
