Sony VPCZ21TGX Battery
Your Sony VPCZ21TGX battery makes your laptop portable so that you can use it anywhere you please. More amps in a battery basically means the longer it will last on a single charge. Not all batteries are the same, be sure to check the model number and compare it to the old one. It is OK to buy a battery with more milliamps, as it suggests the battery will last a bit longer on one charge. What is important is the physical size of the battery as well as the connection.
What signals that my li-ion battery is almost dead?
- The Sony laptop is unable to boot up while not connected to the AC adapter
- The laptop battery has its case swollen and looks like it will explode
- The laptop lasts way less than it used to before it shuts itself down
