Sony PCG-R505EC Battery
Your Sony PCG-R505EC battery makes your laptop portable so that you can use it anywhere you please. It is OK to buy a battery with more milliamps, it just means the battery will go further on a single charge. What really is critical to a battery fitting your laptop is the actual size of the battery and the connection it has. More amps in a battery basically means the longer you will be able to use the laptop on a single charge. Because no battery is the same, make sure and double-check the model number and compare it to the old one.
Clues to watch for in a failing primary battery
- The laptop lasts less than half an hour before it dies
- The Sony laptop is unable to boot up when not connected to the charger
- The laptop battery gets puffy and looking like it is going to burst
