Sony PCG-R505GL Battery
Your Sony PCG-R505GL battery makes your laptop portable which gives you the opportunity to use it anywhere in the house or even outdoors! The more power the battery has, the longer it will last on one charge. Buying a battery with a higher milliamp rating is fine, as it suggests the battery will last a bit longer on one charge. What is important is the connection type and physical size of the battery. Because no battery is the same, make sure and double-check the model number and compare it to the old one.
