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.
I should've taken pictures, but didn't really think of it at the time.
