Li-Ion CR123a - instant overcurrent protection?

[yellow]

Just got some Fenix CR123a,
they dont work in the light I got them for (SF A2).
Seems they instantly have the cells overcurrent protection kicking in.
?
Dont they work in actual high drain lights?
(is the A2 even high drain?)
The A2s led do light up, so low drain ... no problem


... funny thing noted: I bought them because I thought the more than 5 years old FourSevens batts are finally getting bad; but inside the only 1*CR123 light I have, the Fenix ones last about 53 mins each, the Foursevens about 48-50

The lamp has too much current for these batteries.

I didn't think you can run a A2 with 2 16340's. That's a 6 volt light. Could be wrong. It's happened before 😁

3 Keeppower RCR123 plus one dummy work OK in 2x18650 body with TL-3 bulb (1.2 Amp)
Once I tested same set up with FM1794 (3 Amp) bulb, nothing.
3 volt Li-Ion RCR123 are for low current devices.
I have stated this in some other threads too.

That's the setup we used to do with Strion socket in incand A2
No problem with incand bulb since it's regulated but will overdrive LEDs.

Do the foursevens RCR123s work in the A2?

Yes,
give about 30mins of Main beam.


PS: it was/is known that the A2 is a regulated light (one oft the very few incans, that were) and thus safe to be fed w. the rechargeable CRs. Thats why I did not give any thoughts when ordering new ones.
