Sony VGN-CR309E Battery
Your Sony VGN-CR309E battery allows you to move freely about so that you can use it anywhere you please. The more power the battery has, the longer you will be able to use the laptop when fully charged. It is OK to buy a battery with more milliamps, because it simply implies that the battery will last longer. What is important is the connection type and physical size of the battery. Because no battery is the same, be sure to check the part number of the new battery and compare it to the old one.
Signs of a poorly performing li-ion battery
- The laptop does not run longer than one hour while unplugged
- The battery is puffed up and looking like it is going to burst
- The laptop will not turn on while unplugged
