Hey guys, haven't posted in a while but just thought I'd share the results of the battery test that finished up last week: The test was started on April 1st at 09:00 CST (Not an April Fools joke) and PK-A Venezuela lasted 157 days at maximum brightness before the battery finally died. The runner up is PK01-VS at 153 days. Both of these are AA powered optics and are two of the most modern ones that I know of. I have to say I'm surprised at how long these two optics lasted at max brightness. My previous experience was that most of them seemed to day around 4-5 days but it's pretty evident the power technology has dramatically improved in these latest optics. As I always say I still prefer the collimator types over the red dots but these two are very impressive to say the least. Both are rare but I'm hoping we may see them imported more regularly in the future. *My Kobra was not tested due to circuitry issues. (A good test is HERE) PK-A Venezuela - 157 days / 3768 hours PK01-VS - 153 days / 3672 hours EKP-1S-03M - 37 days / 900 hours PK01-V - 21 days / 500 hours PK-AS - 125 hours PK01-VM - 120 hours PK-A original - 96 hours PK01-Vi - 96 hours PK23 - 80 hours Full Test ThreadMore info on the red dots hereZ

Very interesting. Thanks for posting this.
How did you determine when, exactly, the batter died, or did you round the time to the last day that it was witnessed as operational?
Also, I wonder what difference various types of batteries would have in another test; i.e. Lithium vs. Alkaline vs. Rechargeable, etc.
Nice collection, by the way.

I rounded to the previous day.
Because of my travel schedule it didn't really end up being feasible to check them twice a day like I had planned, but they both died when I was in town so the numbers are within 12 hours. I've heard the lithium batteries are longer life than the traditional AA types, I may do some research on the best brand and test again to see if they last even longer.
Thanks for the compliments :beer:
