Sony VPCZ1390L Battery
Your Sony VPCZ1390L battery allows you to move freely about so as to work or play anywhere you please. Buying a battery with a higher milliamp rating is fine, as it just means the battery will last longer. 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 when fully charged. Not all batteries are the same, be sure to check the physical connection and size and compare it to the old battery.
General indicators that your Sony battery is not going to last much longer
- The laptop battery has its case swollen and looking like it is going to burst
- The unit is unable to boot up when it is not plugged in
- The laptop lasts less than an hour while unplugged
