Dell XPS 14 L421X Battery
Your Dell XPS 14 L421X battery allows you to move freely about so as to work or play anywhere in the house or even outdoors! More amps in a battery basically means the longer it will last on a single charge. It is OK to buy a battery with more milliamps, 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. Because no battery is the same, make sure and double-check the part number of the new battery and compare it to the old battery.
Indications of a barely functioning primary battery
- The unit will not turn on at all when unplugged
- The battery gets puffy and looks like it will explode
- The laptop does not run longer than one hour before it dies
