Sony PCG-FX401 Battery
Your Sony PCG-FX401 battery makes your laptop portable so that you can use it anywhere you please. Not all batteries are the same, be sure to check the size and model number in order to make sure it is similar to the one you are going to replace. More amps in a battery basically means the longer you will be able to use the laptop when fully charged. 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.
