Lenovo ThinkPad Edge E520 Battery
Your Lenovo ThinkPad Edge E520 battery makes your laptop portable so that you can use it where you want. 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 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, be sure to check the physical connection and size and compare it to the old battery.
How do you know if your primary battery needs replacing?
- The laptop battery is puffed up like its about to burst
- The laptop does not run longer than one hour before it shuts itself down
- The Lenovo laptop refuses to turn on when not connected to the charger
