The Dell Latitude E5420 and E6420 batteries also lasted longer than the competition's batteries, increasing the time workers could use their systems by as much as 18.2 percent, or an entire hour of working time!
The Dell Latitude E5420 and E6420 withstood damage and protected data, even after three drops. Neither the HP EliteBook 8460p nor the Lenovo ThinkPad T420 emerged intact - each experienced system failure before we were able to finish our testing.
