Sony VGN-NR398E Battery
Your Sony VGN-NR398E battery makes your laptop portable so as to work or play anywhere you please. Buying a battery with a higher milliamp rating is fine, as it signifies that the battery can last for a longer period of time on one charge. What really is critical to a battery fitting your laptop is the actual size of the battery and the connection it has. Because no battery is the same, make sure and double-check the part number of the new battery and compare it to the old battery. More amps in a battery basically means the longer it will last on one charge.
Red flags the primary battery is in need of replacing
- The laptop lasts way less than it used to before it shuts itself down
- The Sony laptop refuses to turn on while not connected to the AC adapter
- The battery has its case swollen and looking like it is going to burst
