That battery will not drop to 3 volt because of load. It's electronically dropped to 3 volt without load or 2.5 volt under load of 1.5A very similar to primary CR123AOK. Did not realize they dropped that much underload. Quite surprised. I would assume that if a battery was designed to be regulated at 3 V, it should output 3 V. Regardless of the load. Within reason.
BTW, primary CR123A has nominal voltage of 3 volt without load. It will drop to about 2.5 volt under load of 1.2 Amp (P60) or about 2.2 volt under load of 2.4 Amp (P61)
