Sony PCG-748 Battery
Your Sony PCG-748 battery makes your laptop portable so that you can use it wherever you fancy. The larger the battery, the longer it will last when fully charged. It is OK to buy a battery with more milliamps, as it signifies that the battery can last for a longer period of time on one charge. What really is critical to a battery fitting your laptop is the physical size of the battery as well as the connection. Because no battery is the same, make sure and double-check the physical connection and size and compare it to the old one.
What are some hints that my li-ion battery is in need of replacing?
- The laptop lasts less than half an hour while unplugged
- The laptop does not turn on when it is not plugged in
- The laptop battery is puffed up like its about to burst
