Sony PCG-F640 Battery
Your Sony PCG-F640 battery allows you to move freely about which gives you the opportunity to use it inside, outside or anywhere your heart desires. Getting a battery with a higher amp rating is OK, because it simply implies that the battery will last longer. What is important is the connection type and physical size of the battery. Because no battery is the same, make sure and double-check the physical connection and size and compare it to the old battery. The larger the battery, the longer you will be able to use the laptop on one charge.
Easy warnings of a declining battery
- The battery gets puffy and looks like it will explode
- The laptop lasts less than an hour before it shuts itself down
- The Sony laptop is unable to boot up when not connected to the charger
