Try unscrew halfway the original switch, your 18650 battery could be oversized.It's back. In full power mode-gorgeous bright grass green! And yes- single 700 mm Long Protected "18650" Nitecore 3500 mAH battery changed to 4.2 Volts on my trusty Nitecore charger.
I took a deep breath and wanted to switch to low power mode and half power- After many trials I got it to switch modes- but only to SOS-where it was stuck. Then after several half press sequences it went DARK.
until I swapped the tail-Cap power button from my other Challenger 2. Then it was briefly stuck in STROBE. After more fumbling I got it to what is either half or full power.
So it looks like my tail cap switch may need replacing.
" Multi-operation mode (no safety lock)
Performs these sequences within the first three seconds after the laser is on to enter different operation modes:
Three half presses: Low power mode
Four half presses: Half power mode
Five half presses: Strobe mode
Six half presses: Full power mode
Seven half presses: SOS mode
The laser memorizes the operation mode that being used for more than five seconds so you don't have to enter the exact combination to switch to a specific operation mode in later use. "
Also the sequence you listed there is for the challenger laser, not for the challenger II, you should able to switch mode by doing one half-tap at a time.
