The LCD meter can show you real time voltage/wattage with real vapor conditions. With traditional voltage meters, it only can show the voltage of the battery in a no-load condition, although it will not show you the drop of the voltage during real-time usage.
The benefit of testing with on-load condition with a quality battery is the voltage will remain as advertised during usage, as compared to a bad battery where the voltage will drop significant during usage.
