Sony VGN-NR140E Battery
Your Sony VGN-NR140E battery makes your laptop portable which gives you the opportunity to use it where you want. The more power the battery has, the longer you will be able to use the laptop on one charge. Getting a battery with a higher amp rating is OK, as it signifies that the battery can last for a longer period of time on one charge. What really is critical to a battery fitting your laptop is the physical size of the battery as well as the connection. 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 old battery.
