Sony PCG-TR Battery
Your Sony PCG-TR battery makes your laptop portable so that you can use it inside, outside or anywhere your heart desires. Because no battery is the same, be sure to check the model number and compare it to the one you are going to replace. The more power the battery has, the longer it will last on a single charge. It is OK to buy a battery with more milliamps, as it signifies that the battery can last for a longer period of time on one charge. What is truly important is the physical size of the battery as well as the connection.
Important clues of a failing li-ion battery
- The laptop does not run longer than one hour before it dies
- The laptop battery is puffed up and looks like it will explode
- The Sony laptop is unable to boot up at all when unplugged
