Dell Inspiron N4020 Battery
Your Dell Inspiron N4020 battery makes your laptop portable which gives you the opportunity to use it anywhere in the house or even outdoors! More amps in a battery basically means the longer it will last on one charge. Buying a battery with a higher milliamp rating is fine, 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. Not all batteries are the same, be sure to check the physical connection and size and compare it to the old one.
Warnings your battery will need to be replaced
- The laptop lasts less than half an hour before it dies
- The laptop does not turn on while not connected to the AC adapter
- The laptop battery is puffed up like its about to burst
