Turned it on works as expected. Now let me digress for a bit. The optic unexpectedly creates a square pattern on one side. It's definitely the optic. I'm not sure what exactly is causing it. I think I'll start a thread later about it since this isn't about batteries.
That square pattern is the diode reflection, it's normal with G2 lenses (and a bit less so with G7). Which wavelength and power is it?
