Sony VPCW221AX Battery
Your Sony VPCW221AX battery makes your laptop portable so as to work or play where you want. Because no battery is the same, make sure and double-check the physical connection and size and compare it to the old one. Buying a battery with a higher milliamp rating is fine, it just means the battery will go further on a single charge. What is truly important is the connection type and physical size of the battery. The larger the battery, the longer you will be able to use the laptop on one charge.
What are some indications that my li-ion battery needs replacing?
- The unit will not boot up at all when unplugged
- The battery gets puffy and looking like it is going to burst
- The laptop lasts way less than it used to while unplugged
