Dell Precision M20 Battery
Your Dell Precision M20 battery allows you to move freely about so that you can use it inside, outside or anywhere your heart desires. More amps in a battery basically means the longer it will last on one charge. Getting a battery with a higher amp rating is OK, because it simply implies that the battery will last longer. What is truly important is the physical size of the battery as well as the connection. 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.
Subtle hints the li-ion battery will soon need to be replaced
- The Dell laptop refuses to turn on at all when unplugged
- The battery gets puffy like its about to burst
- The laptop does not last longer than 45 minutes before it dies
