Sony VGN-SR129E Battery
Your Sony VGN-SR129E 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, it simply means it is a stronger battery. What is 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 physical connection and size and compare it to the one you are going to replace. The more power the battery has, the longer it will last on one charge.
What symptoms are present when the primary battery is dying?
- The unit refuses to turn on when not connected to the charger
- The battery has its case swollen like its about to burst
- The laptop does not run longer than one hour while unplugged
