At last, I get to eat! But I am not as hungry as Saturn was at the end of HIS runtime. Here is why.....
Using my fully charged AW 750mAH R123 cell, my light ran for 68 minutes before the first double level drop.
Then the drops came at one minute intervals, and my luxmeter confirmed each drop with a 50% drop in reading.
I can also confirm that my light blinked once a minute, which I confirmed by noting that the meter reading did not change.
Saturn,
Considering that my cell is a lithium ion and yours is a lithium primary, I wonder why you got 105 minutes to my 68 minutes? Could you elaborate on what was YOUR indication that you should stop the clock at 105 mins.? If you kept the clock going after the first double level drop, then it is possible that your 105 min. reading was made when the light blinked once a second telling you that the battery is about to die. That is not the standard we have been using, to determine the integrity of Henry's lights.
I am hoping that like me, you stopped the clock at the first drop. This shows that a BS primary is a respectable battery and will do well in Clickys.
