More runtime, higher ampacity, lower output resistance (voltage droops less under load), and higher chance of releasing magic smoke when first plugged in (as the batteries equalize).

I can certainly attest to there being less voltage drop under heavy load.

Our forklift cart runs 2x deepcycle marine batteries (70AH each) and only drops 100-200mV under full load of its drivetrain, moving ~1000lbs.
