Sony PCG-K47 Battery
Your Sony PCG-K47 battery makes your laptop portable so that you can use it where you want. The more power the battery has, the longer it will last on a single charge. Because no battery is the same, be sure to check the size and model number in order to make sure it is similar 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 is truly important is the connection type and physical size of the battery.
Major clues the primary battery is failing
- The unit will not boot up when it is unplugged
- The laptop does not run longer than one hour while unplugged
- The battery has its case swollen and looks like it will explode
