    That's a good point. There are a lot of factors that determine the exact size of the cell. With any production environment, you have plus and minus on everything.

    Yea typically I just look up the light in question on Candlepower Forums or Budget Light Forums and see what people are using. If the cell is satisfactory I just go with that. Most my cells are AW Li-co's or IMR's and those are generally small compared to the high capacity other brands.

    About RCR123A

    There are a huge amount of troubles with rechargeable RCR123A batteries. Overheating, defective, leaking, exploding . .
    Reason is that the main (quality) manufacturers like Sanyo and Panasonic donít produce cells in the format usable for RCR123A. Therefore the batteries that are made in this format need to come from lesser manufacturers and are mostimes mediocre.

    Second reason is the low C-rating of these batteries. Too low for powerful flashlights we have today. That means they are underperforming (low endurance) and also overheating easily.

    - - - - - - - - - - - - - - - - - -

    The right way of choosing a flashlight should begin by choosing the battery-type.

    1] First ask yourself how you will use it? In what way?
    2] Then you choose a battery-type that fits your use.
    3] Now you are able to look which flashlights are available to choose from.

    Pushing a RCR123 at 2c or a CR123 at 1c with some is very easy. As you mentioned this can be dangerous. I don't think even with Panasonic or Sanyo's touch it would be any safer; Lithium cobalt cells like AW are extremely well made but are against capacity and chemistry limitations.

    The real answer with any high-current light and smaller cells is to go with an IMR. In theory you could run a IMR16340 at 4 amps with no problems besides abysmal runtime. In reality something with more than 550 optimistic Mah would be a wiser route. Your flashlight would burn for longer than a birthday candle.

    I want to believe reputable brands that recommend CR123/RCR's as an option are doing so with some foresight. Still, I'll take a 18650 in replacement any day.

    Here is some testing by HTJ on small cells and 18650's.

    So last week I bought some 18650's (marked Nuon) from BatteriesPlus (BP) store, got them home to find out their too long!! Won't function in my Fenix PD35. I have something called Trust Fire's running in them now, and they seem to work fine. The BP's are about 3/16inch longer than what I'm currently using.

    I call up the manager (the store is an hour from my house) and tell him this, he says he has seen this happen before, and one option I have is to cut the outer wrapper off and inside their would be a smaller battery. Well I did that, and all it revealed was a pink battery with Samsung printed on it, but there is nothing else to be done to make it smaller.

    I go to the store yesterday, was able to return the one I didn't cut into but not the other, which kind of ticked me off because I followed the managers advice, which turned out to be not correct. Anyways, this info might be helpful to some.

    That happens. CPF has a lot of threads about 'does battery X work in light Y?' I used to always check those out, but recently, everything I've bought has fit and I've gotten lazy. That will bite me one day soon, I'm sure.

    Mostly AWs but I have a couple of the Fenix ones as well.

    That PD35 rocks, BTW. From my upstairs window, I can light up the whole backyard with ease.

    Yeah I'm enjoying TURBO mode, and the strobe is quite intense.

    I ended up selling my brass Macs SST-50 EDC. The heavy three-mode light was great but I have one very similar in copper that rides in my winter coat.

    This is a Peak Eiger Ultra High CRI, keychain body with a Dark Sucks titanium clip:



    I also grabbed a Oveready Eiger Mule head with a Nichia 219 High CRI LED. No reflector so it's all flood with no reflector, similar to a Zebralight H501 or H502.

    I just reflowed a Nichia 219 onto my Maratac Cu AAA.
    The color rendition of these emitters are amazing.
    I just love this little copper light, running off a 10440 and now high CRI.

    Blerv, nice tritium. I have a few just like it. Justin (I'm pretty sure that's his name, iknitsteel) does very nice work.

    Thanks Donut It's quite bright but a little bulky.

    I was looking at these. Really cool idea and I like that you can easily change out the vial. Just not sure I wanna spend another $40 on something that glows.
