Sony VPCYB33KX Battery
Your Sony VPCYB33KX battery makes your laptop portable so that you can use it 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 actual size of the battery and the connection it has. The larger the battery, the longer you will be able to use the laptop on a single charge. Not all batteries are the same, be sure to check the model number and compare it to the old battery.
Some clues the li-ion battery will soon need to be replaced
- The laptop lasts less than an hour while unplugged
- The Sony laptop will not boot up while unplugged
- The battery gets puffy like its about to burst
