    How tough are Surefire's incandescent bulbs?

    I've never had a SureFire light die on me or blow when dropped, but I don't use SureFire incandescent much. I did drop a first generation G2 onto carpet from about 5' up and the beam ended up slightly distorted, ie had ring artifacts.

    Eneloop AA: leak? rust?

    Looks like rust, but who knows for sure. Some of my eneloops looked like that after using them in an R/C boat.

    Why do rechargeable produce more light?

    I believe many rechargeables produce more light (than disposables) despite lower voltages because of their lower internal resistance.

    Ene/Dura-loop roll call - how many?

    I have 0 Duraloop AAs I have 20 "shiny label" (new) eneloop AAs I have 26 "clear label" (original) eneloop AAs I have 12 "clear label" (original) eneloops AAAs

    Fast chargining and heat

    Gotcha Thanks again for your help.

    Fast chargining and heat

    So then besides a partially charged battery (false peak), what's the disadvantage of externally cooling a cell while it charges?

    Fast chargining and heat

    Ahhhh, ok. But if the charger detects the peak earlier due to the lower cell temperature, how would that harm the battery? Thanks for all the great information everyone! :)

    But if temperature could be externally lowered, would oxygen generation be lowered as well?

    Fast chargining and heat

    I understand that. I wouldn't expect external cooling of the cell to completely counter all the heat generated from extreme charging rates. However, assuming a fast charge had to be done, would external cooling be better than nothing? Perhaps JWP_EE has answered my question?

    Fast chargining and heat

    Hmmm, that's the best explanation I've heard so far. It certainly makes sense.

    Fast chargining and heat

    Thanks. I came across that thread, but I don't think they directly addressed my question. Still a good read, though.

    Fast chargining and heat

    I use eneloops (AAA and AA) in my primary lights. However, if I wanted to recharge the cells very quickly, say at 2 amps with AAA or 5 amps with AA eneloops, I'm sure most of you would not recommend it due to heat build up. But can't I use cold air when charging the cells to ameliorate this...

    NIZN VERSUS NIMH

    Thanks for the suggestion Anthony, but can you explain where you got that information from? I thought on the website (at least one of them for NiZn) it called for CC until a certain point, then CV until the end of charging. I have been told this is how Li-Po and Li-Ions are currently charged...

    NIZN VERSUS NIMH

    So I take it NO ONE knows how to charge these cells in series?

    AAA vs AA

    I like AA batteries for their ability to handle high current draws more efficiently than AAAs (someone might have alluded to this earlier).
