Sony VGN-CS220J Battery
Your Sony VGN-CS220J battery makes your laptop portable which gives you the opportunity to use it where you want. Because no battery is the same, be sure to check the physical connection and size and compare it to the one you are going to replace. More amps in a battery basically means the longer it will last when fully charged. 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 actual size of the battery and the connection it has.
How do you know if your battery is in need of replacing?
- The unit will not boot up while unplugged
- The laptop battery has its case swollen and looks like it will explode
- The laptop lasts way less than it used to while unplugged
