Dell Latitude 5420 Battery
Your Dell Latitude 5420 battery allows you to move freely about so that you can use it where you want. The more power the battery has, the longer you will be able to use the laptop on a single charge. Buying a battery with a higher milliamp rating is fine, it simply means it is a stronger battery. What is truly important is the connection type and physical size of the battery. Not all batteries are the same, be sure to check the physical connection and size and compare it to the old one.
Major clues of a failing battery
- The laptop lasts way less than it used to before it dies
- The laptop will not turn on while not connected to the AC adapter
- The laptop battery is puffed up and looks like it will explode
