Zebralight SC52 & Nitecore EA4 Change in Throw Over an Hour

Should not be surprised 1 battery vs 4 batteries. As for the SC52, of course 1 Duraecll can't do what 1 Eneloop can do.

No, that was not the point. What surprised me was how close the EA4’s performance with Duracells was to its performance with Eneloops. Four Duracells vs four Eneloops in EA4, little difference; one Duracell vs one Eneloop in SC52, huge difference. Thus my comment that in relative terms the SC52 squeezes a lot more out of its single battery.
