Sony VGN-Z790D Battery
Your Sony VGN-Z790D battery makes your laptop portable which gives you the opportunity to use it anywhere you please. The more power the battery has, the longer you will be able to use the laptop on a single charge. Getting a battery with a higher amp rating is OK, because it simply implies that the battery will last longer. What is truly important is the connection type and physical size of the battery. Not all batteries are the same, be sure to check the physical connection and size and compare it to the one you are going to replace.
