D10 "rescue me" feature ?

[mr_maurice]

Today I noticed a funny thing on my D10, and I could not find any previous report of it on cpf.
It had a low eneloop inside (multimeter says less than 1v)
When fully tightened, it emitted a quick flash roughly every 1-2 second, no matter what I did with the piston
I made a short videos that shows it.

Note that it works like a charm otherwise, but it's still an unexpected behavior.
Undocumented feature ?

My guess is that the battery has just enough voltage to activate the LED and when it comes on the voltage drops the LED goes out and the battery recovers some voltage and it repeats. When you twist it tight that turns the D10 on and for the piston to deactivate it there has to be power to the driver which it only has in short bursts so it stays in the on position from memory. Just a guess though. When I ran a primary 123 dead in my Nitecore Extreme after the very long moon mode it would do the same thing.

When I did runtime tests on my D10 and EX10, they did the same thing at the end of the run.

That's like the NDI's low voltage indicator feature. Maybe the D10 has it too?

Yeah, my NDI does it after 10min of runtime........ and there's no way to SHUT IT OFF! :hairpull:

I just remembered selfbuilt's runtime tests, and he clearly states that D10 and NDI shared the same circuit.
While the NDI has a low battery indicator, maybe the D10 has the same.
