I have a Surefire 9P setup using 2-AA's and a low voltage XP-G 3 mode drop in. I was using 2 NIMH AA (Older Energizer type) batteries, and trying to get a gauge on run times. When the light finally ran out (lumens down below 10 approx), I took the batteries out and checked them both with a DMM. The bottom battery next to the tail cap was at about 1.02v. The top battery next to the drop-in was reading .01v. I thought that the batteries would run down together? Is this normal to have a battery go down that low? This is the first time that I noticed this, as I usually check every time. They are usually very close in the readings. Is it a bad cell? I charged them back up, and they both came off the charger at 1.24v.
