Testing the 14500 IMR – AW vs. Lighthound

14500- 16340 batteries just score the rug. LMR will just barely kick the amps (depending on the quality) just a bit in this batt. size. So it's not all abot the mAh. I guess.

Here in the US get AW LMR to play with.

why the test are only at 1.5 amp?

we use imr batteries when we need too much highter currents

He'll be testing 3amp soon, possibly tonight. I think he mainly wanted to first test to see what, if any difference the batteries would show. Best to start slow, I guess. But yeah, 3 amps (and beyod, chuckle) would be more appropriate to see, but he knows that also. Remember this is his stuff though and these drain tests are hard on batteries. Then again, he mentioned his 14500's aren't of much use to him... >) <---- (BTW, why don't my 'devil horns' show up?)

Could people stop saying that the word "Lithium" starts with the letter i ??

Nice review just the same. I need to get me a few decent LMRs some time.

I sympathise, but I fear that you've lost that battle.

There's a southern suburb of this town called Footdee which is called "Fitty" by everyone (Including me). Originally it was called Futty, but some Victorian idiots thought that sounded indelicate and renamed it Footdee which immediately became Fitty.

Swimming against the tide is fun, but it tends not to get one anywhere...

Do you all really have so much free time that you find it necessary to argue about a series of letters on some batteries to entertain yourselves? I don't give a flying fig if its supposed to be an L or an I. The people who sell them call them IMRs. Apparently you all know one thing that they don't. With that and a dollar you can get a cup of coffee. Congratulations.

Because in cells this size 1.5A IS a “high current”. Regular 14500s sag more and have the same OR LESS capacity at currents approaching (or exceeding) 2C

Unless the particular Lighthound IMR I have is sub-par, this graph shows the clear superiority of the AW cells at this discharge rate. I decided to run these cells down to their recommended cut-off since the cells would quickly bounce back due to the high drain rate.

The Lighthound IMR falls on its face here, delivering only 255mAh before dropping below the recommended 2.75v cut-off. The AWs are, in my opinion, awesome. All of them delivered 600+ mAh at 5C! They are recommended to go as high as 8C, where the LH one is only recommended up to 5C.

These aren’t the results I was hoping for (and I’m sure some of you, as well), but I have to admit that I’m impressed by the AW cells.

Graph:

3 AW IMR 14500 and 1 Lighthound IMR 14500 @ 3A

True.

You should probably check where in the world people are before making statments like that.

I used to live in Altrincham, which is pronounced Altringham. It was spelt wrongly in The Domesday Book and has been spelt that way ever since.

I think the rates you're quoting only apply for destinations within the U.S.

For those of us who live elsewhere different and much higher rates apply. I find the one pound flat rate package (about $13.00) works best for me. A nice feature of the LH checkout process is that it shows the weight of your purchase to two decimal places. Based on that weight indication I have added or subtracted a cell or two from my order, trying to get as close to the one pound limit as possible without exceeding it.

Final test with the AW IMRs only:

Graph:

AW IMR 14500s at 4.8 amps

Capacity @ 4.8A - 296mAh - 335mAh

The variation between cells shows when you push them to their limit. I wouldn’t push them this hard in a light so this test is purely academic. In fact I doubt I’d ever use them at 3A. All of my use of 14500s is under 1.5A so I could be entirely happy with the Lighthound cells for a small EDC like a Quark Mini.

Your conspiracy theory is WAY off, for starters R doesn't stand for Rechargable but for Round type. It's the I that stands for "Lithium-Ion [Rechargable]" (or correctly, i for Lithium-ion). It's not supposed to be "L" for "Lithium" since that is incorrect and could be any other number of lithium chemistries.

This thread has attracted a lot of CPF-like assholeness/negativity uncharacteristic of BLF. I ask all to know that out and stick to the good stuf and leave out the jerk part. It's not welded onto your personality, even if it's in you. I suggest (if it helps) you write down your insult, go big too, then just delete it, and leave only the on-topic part.

As a student of conspiracy theories, I take it as an insult that you'd call my surmisement such. In fact, if you even know what a conspiracy is (look it up), my description would qualify as the opposite of a such a thing. Call it an "ignorance theory" or "incompetence theory", "herd mentality" theory, but no need to get jerky--and inaccurate at the same time. I'm always willing to learn. Your assertion is that I stands for Ion, and R stands for Round. What does the C stand for then? I freely admit that I was surmising a translation, but it made a lot of sense. Are you saying it's purely a coincidence that "iCR" is Lithium Cobalt Rechargeable technology, and ALSO 100% coincidence that so-called "iMR" is Lithium Manganese Rechargeable? And what does the R in RCR2 (rechargeable CR2's) stand for then? Because CR2's are already round. How about Panasonic's NCR? Just a coindience again, that the proprietary feature of that line of batteries is Nickel, in addition to cobalt and of course lithium?

And since I'm freely admitting I'm basing my assumption on the pure logic and strength of the coincidence of the above examples, care to back yourself up as to what you're actually basing your assertion on? (There's a lot of insult surround this, by people who don't back themselves up, I've noticed, nor admit when they're wrong.) There's nothing wrong with assumptions, but they should be disclosed, and the logic behind them solid. Your assertion that ICR stands for "lithium [something ?] round" seems wanting, and you did not bother to explain what "iMR" would stand for either. You neither backed yourself up, nor pointed out that you were only assuming either, nor did you seem to notice that your assertion did not fully define the acronym you seemed to think you were authoritative on.

CR2 is the name for a size of a primary cell: the 2 means that its 1/2 the height of an A cell, the CR stands for.... cylindrical.

My last post goes for you too Mitro. Seriously, go back to CPF if you're going to be like that. There are plenty of people like you over there for you to mingle with and belittle.

I've publicly praised/complimented you at least twice while you've been here, and really, all I've ever gotten from you is negative vibes or something close to an insulting, terse tone myself. And certainly you've never had a kind word toward me at all. Seems it doesn't matter what the topic is, for you to act like that. You didn't direct the above insult at me, but that shit is not welcome on this board--says me. And as the primary instigator of the "IMR is LMR" rebellion, it might as well be me you're talking (down) to.

I find it funny that you'd insult a member for having "so much time on their hands to entertain themselves" with such a trivial matter. What do you think you're doing? Do you really have enough free time to create a thread where you hook up not just one but four AA-sized batteries to an elaborate system, including a computerized chart, in order to eke out exacting, if not elaborate information on which obscure battery beats the other obscure battery, which you even admitted you don't even have much need for? Do you realize how ridiculous this would seem to people outside this hobby? Yet you find someone who is exacting and precise in their language, or a native English-speaker who refuses to write recycled Chinglish, and all you have is an insult?

Maybe I should phrase it differfently. Do you have any concept that someone would have an interest or care outside of flashlights? In life, I've found almost everything comes down to communication, including almost all problems in life--so being exact and precise in language is NO vice. And that last point is something which you could take a lesson from, wasting your own time entertaining yourself reviling against a fellow member who's done nothing wrong and who certainly outmoted you in terms of civility of discourse, whatever sin you perceived in his own communication.

Seriously, which is more ignorant: learning what a serif is (which you encounter in your life far more than flashlights), or measuring the difference in millimeters between a S7 and Z41 tailcap--which you yourself have done, posted about, and taken photos of? I could easily fling a similar insult, but the fact is, being exact and precise about what we do is one of the things which sets us apart as flashaholics... it's often in our personalities, and extends to other facets of our life... Like, with me: communication--I seek precision when I engage in that, outside of flashlights. With you, I'm sure some other positive trait you exact precision on outside of flashlights, which some may consider foolhardy. Doesn't mean it isn't.

You've made some great technical posts, and some great pictorials, and that input has been personally useful to me in my life (because I, like you, have nothing better to do apparently but play with flashlights to entertain myself). But if I had to choose between all I've learned from you, WITH the right you feel to be an overtly dismissive, insulting, know-it-all asshole on BLF, I'd take take no Mitro at all, and none of that knowledge--and that goes for any others of you who would and are starting to do the same. There is a place for behavior like that: it's called CANDLEPOWERFORUMS DOT COM.

And the post above mine is why I still prefer CPF to BLF, because of a few people. There are many valuable resources here, but.... The difference between the z41 twisty and l2-s7 is significant in the actual torch world- the s7 has more resistance, is shorter, so, many torches don't work with the s7. "who refuses to write recycled chinglish"? I'm sorry, but you can't expect the whole world to speak your language.

Have fun,

Dave

P.S. : Thanks for teaching me about serifs.

I won't waste anymore time posting anything on the subject this forum is supposed to be about. brjones, are you sure this is where YOU belong? I wanted to discuss flashlights and related hardware. Thanks for completely belittling my contribution of actual data.

Whoa! Guys, I don't have a dog in this fight... (for non-southerners: I'm not taking sides). But aren't y'all just putting a little bit too much weight on all of this? I've enjoyed posts by all of you...Brjones, Mitro, and srfreddy (mtm's kinda new....).

I've always just typed IMR, even though I know it's LMR. Here's why:

There are two types of folks out there,

-Those that know what an IMR battery is...

-And those that know what an IMR is but really know that it's LMR (and get ticked off).

I figure I cover both camps by using IMR. (Sorry, brjones, I don't mean anything by it... )


I was taught that there are three types of folks out there.

1.) Those that can count

b.) and those that can't.
