Make your Dell Latitude E6420 XFR battery last longer:

1. Should I totally discharge and recharge my Dell Latitude E6420 XFR battery occasionally to make it last longer?
   A: No, discharging and charging does not increase the life of a Li-ion Dell Latitude E6420 XFR. And with current Li-ion batteries this practice does not improve the runtime of the battery. This practice is a holdover from the days in which NiMH batteries were used.
