Sony PCG-731 Battery
Your Sony PCG-731 battery makes your laptop portable so that you can use it inside, outside or anywhere your heart desires. Getting a battery with a higher amp rating is OK, as it just means the battery will last longer. What is truly important is the physical size of the battery as well as the connection. More amps in a battery basically means the longer it will last on one charge. Because no battery is the same, be sure to check the physical connection and size and compare it to the old battery.
Easy warnings the li-ion battery is in need of replacing
