Dell Latitude E5420M Battery
Your Dell Latitude E5420M battery makes your laptop portable so that you can use it where you want. The larger the battery, the longer it will last when fully charged. Buying a battery with a higher milliamp rating is fine, as it just means the battery will last longer. What is truly important is the connection type and physical size of the battery. Not all batteries are the same, make sure and double-check the size and model number in order to make sure it is similar to the old battery.
Simple signals your battery is in dire straights
- The battery has its case swollen and looking like it is going to burst
- The laptop does not run longer than one hour while unplugged
- The Dell laptop does not turn on when it is not plugged in
