Quark Moonlight Runtime Test

[flatline]

I've just started a moon mode run time test on a SAFT 3.6v 14500 Li-SOCL2 2600mah primary on the same Quark AA (XP-E R2) that got 300+hrs on an Eneloop.

I tested current draw at the beginning - 1ma. Do the maths

If you're taking tail cap current readings, could you do all of the modes (moon, low, medium, high, max)?

Sounds to me that it is a primary cell (think I found a website about $5 each) so not sure if Amigafan has/wants to do a lot of tests (and probably could only do moon and low right? sounds as if this type of battery can't take barely any current output). Sounds like it is made really for micro amp current.


from a website I see :
"[SIZE=-1]The LS14500 cell is designed specifically for long-term (3 to 15 years) applications, featuring a few UA based currents and periodic pulses, typically in the 5-150 mA range. "[/SIZE]

The reason I asked is that when playing with ER14505 cells which are supposed to be able to handle sustained currents up to 100mA, I could run moon-mode indefinitely, but nothing higher for more than a second or two, not even low mode. So I assumed that low mode had more than a 100mA draw at the tail...but sadly, I never confirmed that with a multi-meter.

I guess my earlier post was a victim of the database debacle.

Anyway, as I said before I feel silly reporting this but....

Quark MiNi AA: 41hrs it was still on, at 46 hrs it was dead.:shakehead

D10 GDP: 68hrs it was still on, at 73 hrs it was dead.

Both lights died while I slept.

I did get better results in the Qmini from the KS alkie (5 hrs). Still disapointed.

I am happy with the D10. Compared to most lights it did very well....but not against the Quark AA.

OK that's done so............GO QUARK AA!!!!



(I can't remember how I worded my original post but this is pretty close.)

...and I said that sleeping is overrated

Quark now at 419 hours continuous, no changes, no flickering, nada... still going.

61 hours to go until we get 200% rated runtime. :duh2:

 

[mitro]

I feel like I'm re-inventing the wheel.

264 hrs. on the Eneloop. Still flickering slightly.

EDIT: Scratch that. I clicked it on and off again and it wouldn't come back on.

Eneloop pronounced dead at 264 hours. Ending voltage was .91v 60 seconds after last light. Previous break-in of this cell reported 1943 mAh capacity. I am running the cell though another break-in cycle to get a more recent test of the capacity. This cell is about the midrange of my Eneloop/Duraloops.

I've decided to move on to test low with an AW 14500. Still trying to figure out my methodology on the best way to preserve the battery. I'm probably going to pull it and test it at regular intervals and just stop when it gets sub 3v (In case the protection doesn't kick in).

I had to terminate my L91 test today. My son asked me for a flashlight to take with him on a trip to Spain and that was the best one to give him. Sorry. I can restart on one of my Ti AA's. I think they are R5 bin, but I'm not positive.

 

[amigafan2003]

Amigafan2003: are you seriously going to see that through? pretty long time without being able to use that light on anything else than moon mode :nana:

Plenty of other flashlights to use, inc a Ti AA

Whoa!!!! Do these charge in the Pila IBC charger

No, they are primaries.

So I assumed that low mode had more than a 100mA draw at the tail...but sadly, I never confirmed that with a multi-meter.

Measured tailcap current was 1ma on moon, 11ma on low and 55ma on med - so the SAFT 14500 should be able to do those three modes without issue.

Hmm...I may need to try the ER14505 again in my QAA. At those currents, it should have been able to support modes higher than just Moon...

The Quark has passed 432 hours (18 days continuous) with no changes to report.

 

[Darvis]

The Quark is at 442 hours with no changes to report. In two hours, it will be at 444 hours, or as some may say...

444: Sign of the Quark :devil:

SO close to 480 hours... come on, you can make it!

(I never thought I would be cheering on a flashlight :nana

 

[Darvis]

Well going to start a little thread with the 4Seven lights and the info from these tests (and mini tests) - Darvis, Amigafan, Mitro, I am taking the info from this and putting it in there. Everyone else if you see other places with more testimonial/run time tests for 4seven lights, point them out to me so I can add stuff to it! I think it will be great to have at least all the 4seven light information in one place.

take a look at the format and if you have any suggestions lemme know!

Just had a look at this, really well done!

 

[wantsusa]

Thanks, it's just leg work really.

Plus every time I update it...it makes me want to get more flashlights!

[Beacon of Light]

Wow I forgot about this thread way back before it was at 100 hours or so. 400+ hours is remarkable. Like Darvis said, this circuit with a AAA would still get over 100 hours on a similar low lumen light. Let us now pray the E01 killer will have a super long runtime. haha

 

[guiri]

Sure but why do AAA when there is AA and it's not that much bigger?

Because one can

As good a reason as any..
