Sony VGN-SZ470N Battery
Your Sony VGN-SZ470N battery makes your laptop portable which gives you the opportunity to use it anywhere you please. Because no battery is the same, make sure and double-check the part number of the new battery and compare it to the old one. Getting a battery with a higher amp rating is OK, because it simply implies that the battery will last longer. What really is critical to a battery fitting your laptop is the connection type and physical size of the battery. More amps in a battery basically means the longer it will last when fully charged.
