Sony VGN-NS290J Battery
Your Sony VGN-NS290J battery makes your laptop portable so as to work or play anywhere in the house or even outdoors! Getting a battery with a higher amp rating is OK, as it signifies that the battery can last for a longer period of time on one charge. What is truly important is the actual size of the battery and the connection it has. The larger the battery, the longer it will last when fully charged. Because no battery is the same, be sure to check the physical connection and size and compare it to the old battery.
Symptoms of a weakening Sony battery
