I'm quite liking my Olight H2R purchased this summer - it gets used frequently during the week for everything from surface-mount soldering to dusting. I was disappointed that the (Canadian) vendor said they were unable to sell me a spare battery for this lamp. I had initially hoped to use another spare 18650 I have but found that I could only get the two lowest settings to work, and the headlamp "blinked" indicating low battery (even on a freshly charged cell).
I think what was happening is that the button terminal on the + end of the 18650 was only touching the "ring" terminal in the Olight end cap (which on the proprietary Olight battery touches the negative ring terminal around the positive button) - the lamp was being back-fed through whatever charging circuitry is in the tail cap.
I cut out a little circle of report-cover plastic and cut a hole in the middle. I took a tiny magnet out of the drawer of magnets and put it on the batery terminal so it would touch the + contact of the tail cap. It works! I can cycle the lamp through all settings.
I did find that using the Fenix ARB-L2S that turbo mode (2300 lumens) only came on for a few seconds, then the lamp would go off for a minute or so. I surmise the ARB-L2S protection was coming on when the Olight H2R started demanding 4 amps. However, the 600 lumen setting seems to work well. I suppose I could pick up some kind of high-drain battery that would support the H2R load.
Anyway, this gives me a fall back. Until I can purchase a spare Olight battery, I can use this system to substitute an existing spare and still have usable output and run time. It's a bit more fiddly than I'd like, but acceptable for the gentle use cases I currently have. It's not like I'm caving with this light or even going on industrial site inspections.
