Sony PCG-GR290 Battery
Your Sony PCG-GR290 battery makes your laptop portable which gives you the opportunity to use it anywhere you please. 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 physical size of the battery as well as the connection. Because no battery is the same, make sure and double-check the model number and compare it to the old one. More amps in a battery basically means the longer it will last when fully charged.
