Sony PCG-F340 Battery
Your Sony PCG-F340 battery allows you to move freely about so that you can use it where you want. Not all batteries are the same, be sure to check the part number of the new battery and compare it to the old one. 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, it just means the battery will go further on a single charge. What is important is the actual size of the battery and the connection it has.
