Hm, weird, link is working here. I fixed it 2 times, iPad was acting up.
Perhaps you haven't tried after the 2nd fix?

The Ultratac K18 running the 3.7 li-ion battery is amazing for a light of this size. About a month ago, and after a fair amount of research, I decided on an Olight i3e. This is a fantastic, really bright keychain flashlight. A week later, I saw the K18. Being a bit of a flashaholic, or whatever you would call it, I knew I had to get it. Running a AAA battery, the K18 is comparable to the Olight i3e. Stick that 3.7 volt li-ion in, and it's fantastic. Much brighter. Shockingly bright for its size. For the people talking about the lockout feature, mine has it. Double-click and I'm all set.
Does anybody know how many ma are used from an nimh battery in high medium and low brightness modes.
Thanks
John
From a 1.2v nimh cell calculated using run times from this and other reviews- all are approx values but should be close.
High- 800mA
Med- 200mA
Low- 25mA
Thanks for the Information
EDIT: At 800ma how do they get 1hr runtime on an alkaline battery, Even at 400ma i doubt they would get 1hr even down to 10% light output.
John.
I would like to see an Lifepo4 10440 in the K18 with it`s virtually flat discharge profile, though at 280mah most likely 200mah it might not last long but it would be interesting to see.
EDIT: I decided to order a 4pack of Soshine brand just out of interest, hopefully i will get them in a month or so.
John.
I have been happy with the soshines, small button top, fits everything, hold their voltage well deliver plenty of current and charging them up from above 3v they show about 320 mAh of charge. I have many quality brands of li ion cells but these are the first 10440 i have owned and i rate them as very good so far.
I do not own or have any experience with Lifepo4 but because of their lower nom voltage, im guessing they might not drive the k18 to its max output if this is important and maybe someone who has tried them can comment.
What charger is best for 10440's these days? My only experience with small 4.2V was my old Quantum D2's 10180 USB charger, which was very handy.
I take it normal full-size 4.2V LiIon chargers like the Nitecore D2/I2 aren't great for small cells, even if they claim to be compatible?
And I presume the Ultratac 10440 charger also charges Efests IMR 10440's?
I'm trying to decide whether to just buy the K18 bundle on Amazon with the generic blue 10440 and USB charger, and/or buy a separate efest imr 10440 and some other charger.
Thanks for the info, Tinder and Capolini.
Just ordered the SS K18 for $28.85USD and Xtar XP1 for $9.49 from Amazon, and an Efest imr 10440 from illumination supply, they only had one in stock.
