Which RCR123a Chemistry should I use? IMR vs ICR vs IFR

Lighthound has them. I get my 16340 AW ICRs and LiFePo4s at a couple different online Ecig stores. They seem to like AW.

Thank you ‘Ouchyfoot’ for the excellent description! Right, I knew that with the ICR I would loose medium mode on the Eagletac d25c (it does still retain low) I just didn’t know that it was called direct drive. I will have to keep this in mind. I might use a ICR for tactical use e.g. night in the city and IFR for longer use e.g. camping.

Would anyone suggest a good IFR?

Will the i4 intellicharger charge an IFR? Does it still have to be 3.7v to charge it?

No, the intellicharger will not charge IFR cells. As was recommend above, the MP2 will charge both ICR and IFR CR123 sized cells.

Thank you. I just read in your review that you suggested the MP2. Thank you again for the great review and advice!! A+

Yep, it's a good charger. There is a review here.

I have many chargers, and the MP2 is the only charger I use for RCR’S (16340) batteries. The 250mA charging rate is ideal for these smaller capacity cells. The fact that you can switch between 3.0v and 3.6 v makes it extra handy. Plug it into the wall, or a USB port. This is a safe and dependable charger.

I’ve been telling everyone who will listen about this charger, and I never saw that review.

I think I’m set on the MP2 charger because I like the benefits of accepting all rcr123a chemistry’s. I am trying to narrow my battery search down so that I have the best batteries. Tell me what you think.

(AW RCR123a Protected 3.7V 750mAh $9.5) VS. (Nitecore RCR123A 2-Pack 3.7V 650mAh $15). And I had a hard time finding IFR batteries in a name brand? (Tenergy RCR123A 3.2V 750mAh LiFePO4 $7.5)

Those are all good batteries.

Thank you! I read that AW123 protected Overcharge protection is at 4.35V - Overdischarge protection at 2.45V and Advertised Capacity: 750mAh, Measured Capacity: 563mAh but I’m not sure how many amps it supplies or how many recharges they claim. The Nitecore123 calms to supply 4amps and 500 recharges but i can’t find anything else as far as specs. I’m told anything less then 2.8v you start impacting battery life. Quickly searching I heard tenergy might have problems :-/

Review on AW123 here if you scroll down his blog a little. I’m still trying to find a 3rd party comprehensive review for nitecore123, although they do give a lot of information on there website.

AW RCR123 750mAH Actual Capacity! | Candle Power Flashlight Forum!

Far fewer options out there in IFR. Their lower capacity usually means people only use them when the light really can’t take the higher voltage of other options. I’d trust the Scaru’s opinion on these more than mine.

what do you think about the xtar mp2 vs. ultrafire wf138 charger?


Yeah, tenergy LFR I’ve heard mixed reviews on but It might be my only option to have a medium function on my Eagletac d25c and have have rechargeable.

Solarforce blue-white 16340 are currently the best.

Looks good. I guess it is between nitecore (2 for $15) and solarforce (2 for $11). Leaning towards solarforce now. Good performance and cheaper.

I heard size might be a problem with the Solarforce. I’ll be putting it in an EagleTac d25c… might be hard to make sure they fit given I haven’t bought it yet.

Solarforce DIA = 16.7mm, Length = 36.1mm
NiteCore DIA = 16.6mm, Length = 34.8mm
Tenergy DIA = 17mm, Length = 34.5mm
AW DIA = 16.62mm, Length = 34.29mm

*EDIT: EagleTac d25c compatable battery size: Diameter : 16-16.9mm, Length : 34-34.9mm
So Solarforce wont work for this flashlight. Do you have any thoughts on nitecore vs Aw

1. SF

2. Efest

3. Trustfire

4. AW

Nitecore cells are good in general, but I dont know about the 16340.

Ualnosaj wrote something about them here:

Nitecore 16340 650mAh = 668mAh

Nitecore 14500 750mAh = 782mAh

So they should be fine.

AW or Sanyo are both good. The Nitecores use Sanyo cells. Sanyos are a little fatter, and I have a couple lights the wont fit in. AW fit in every light I’ve ever tried them in.

I havent seen 16340s from Sanyo.

My bad! Sorry. Ignore that. I was thinking about the 14500 Sanyo cells. Sometimes when I’m thread hopping…I get mixed up.

I've seen websites state that the Nitecore 16340 does use a Sanyo cell, so I thought thats where you got that info. But there is no 16340 by Sanyo..^^

So you were not wrong, just confused. Thats fine. :D

Thanks for the info and links! Does anyone have info on the trustfire rcr123a. I have found some that are priced very well and am curious to there quality/performance.
