Sony VGN-SZ740 Battery
Your Sony VGN-SZ740 battery makes your laptop portable so as to work or play wherever you fancy. It is OK to buy a battery with more milliamps, it just means the battery will go further on a single charge. What is important is the actual size of the battery and the connection it has. Because no battery is the same, be sure to check the size and model number in order to make sure it is similar to the one you are going to replace. More amps in a battery basically means the longer you will be able to use the laptop on a single charge.
Warnings Sony battery needs replacing ASAP
- The laptop lasts way less than it used to before it dies
- The laptop battery has its case swollen and looks like it will explode
