Sony VGN-TT190N Battery
Your Sony VGN-TT190N battery makes your laptop portable so as to work or play anywhere you please. The more power the battery has, 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 size and model number in order to make sure it is similar to the one you are going to replace. Getting a battery with a higher amp rating is OK, it just means the battery will go further on a single charge. What is truly important is the physical size of the battery as well as the connection.
Major clues the li-ion battery is going out
- The battery has its case swollen and looking like it is going to burst
- The laptop does not last longer than 45 minutes before it shuts itself down
- The unit will not turn on when it is not plugged in
