Sony VPCEE21FX Battery
Your Sony VPCEE21FX battery allows you to move freely about which gives you the opportunity to use it where you want. The more power the battery has, the longer it will last on one charge. Because no battery is the same, be sure to check the model number and compare it to the old one. Buying a battery with a higher milliamp rating is fine, because it simply implies that the battery will last longer. What is important is the connection type and physical size of the battery.
What warnings should I watch out for to know if my li-ion battery has to be replaced?
- The Sony laptop refuses to turn on at all when unplugged
- The laptop does not run longer than one hour while using the battery only
- The laptop battery is puffed up and looks like it will explode
