Sony PCG-R505TEK Battery
Your Sony PCG-R505TEK battery makes your laptop portable so as to work or play where you want. Because no battery is the same, make sure and double-check the physical connection and size and compare it to the old one. Buying a battery with a higher milliamp rating is fine, as it suggests the battery will last a bit longer on one charge. What really is critical to a battery fitting your laptop is the connection type and physical size of the battery. More amps in a battery basically means the longer it will last on one charge.
Easy warnings to watch for in a bad primary battery
- The laptop battery gets puffy like its about to burst
- The laptop lasts way less than it used to before it shuts itself down
- The Sony laptop is unable to boot up while not connected to the AC adapter
