Can anyone please tell me how I would go about changing the battery over in my light please!!! I have so far taken off the lens cover and have undone the 3 x 1.5mm Allen screws to release the outer housing but still can not get to the battery :-( Thankyou

Have you read the user manual for this light? Is there a section on changing the battery? What about that section is unclear?– Paul HJun 13, 2019 at 20:24

I have read the user manual and to my knowledge Paul there is nothing on changing the battery. Please correct me if I'm wrong!!– user43985Jun 13, 2019 at 20:29

Do you a have link to the manual? It's difficult to verify your assessment without it.– Paul HJun 13, 2019 at 20:31

A quick google search turns up this forum entry by user “RNAV”: https://www.bikeforums.net/electronics-lighting-gadgets/1085170-knog-arc-5-5-battery-replacement.html
Remove the trim that surrounds the lens. There are four phillips screws holding the lens in place -- Knog fills these in with epoxy so you can't use them. I dug out the epoxy with a razor blade. Unscrew and remove the lens, and you'll see the LED circuit board. There are three black 1.5mm allen bolts; unscrew these. This loosens the heat shield from the body of the light that holds the battery. Gently slide the heat shield (with the circuit board still attached) forward, and it will reveal the 18650 battery compartment (spring loaded on negative end). Remove / replace battery, and perform steps in reverse to reassemble.
As you can tell, it’s hard to get apart (not intended by the manufacturer) but at least it uses a standard 18650 Li-Ion battery.
Hey bud thanks for the tutorial. I had a big problem getting the heat body out enough. The ribbon cable popped off the led board. But at least it came off clean, and not off the button board!
I want to add real quickly that even though I haven’t replaced the battery yet, I have ascertained the original assembly procedure. The ribbon cable on the led ripped off and I will have to re-solder it. The wire was really just a little too short to get the housing off.
Given that, once you do actually get the light apart and the battery out, you will see that the entire battery tray can be removed. It’s held in by two tabs that grip two notches in the case by the side pressure of the battery. Put it all together first, then firmly snap the entire assembly into the light housing. Prestochangeo!
