Sony VGN-CS280J Battery
Your Sony VGN-CS280J battery allows you to move freely about so as to work or play where you want. Buying a battery with a higher milliamp rating is fine, as it suggests the battery will last a bit longer on one charge. What is truly important is the physical size of the battery as well as the connection. The more power the battery has, the longer it will last on one charge. Not all batteries are the same, be sure to check the model number and compare it to the one you are going to replace.
What warnings should I watch out for to know if my li-ion battery really needs to be replaced?
- The unit will not turn on while unplugged
- The laptop does not last longer than 45 minutes before it dies
- The battery is puffed up and looking like it is going to burst
