    True 1.5v AA and AAA batteries

    Measured at the pins, xenon minimag, fresh alkalines or Hixon 1.5V: 2.65-2.70V. So 10% overdrive, not 20%, and that's assuming it's a 2.4V lamp, which it may not be. Nor do I know at what point the "4-5 sets of batteries" cutoff voltage or time is. Bonus, the aluminum body shields all the RFI...

    What flashlight do you keep in your vehicle?

    I've certainly considered that. $60... and i'm sure I'd need a new NiCd (NiMH? Li?) battery for it. I put the money toward a ML150LR for now, but who knows.

    True 1.5v AA and AAA batteries

    Interesting. I googled further and it's all like 5% life at 20% overvoltage. That lamp must be different. It does have a REALLY short filament. ~8.2V to a 7.2V bulb? 14% overdrive. Yeah, I think the charts are for 12V indicators or 120V illumination. I'll have to try it. Weird I never...

    True 1.5v AA and AAA batteries

    Gads, yes. The new one craps out at about 1.4V! Just use 3 cells if you need more than 2.2V. My old thermostat ran a decade without asking for batteries. I didn't even know it had a (leaking) set of alkalines in it until I replaced it. I assumed it was wall-powered. Really should open my...

    True 1.5v AA and AAA batteries

    I tried a lot of putting higher wattage bulbs in lights, but I've never been a fan of overdriving LEDs or lamps. An exception is turbo modes for brief use. That was never a thing on any hot wire light I've used. 3V vs 2.6V, say, is extremely different as far as bulb life-span. But, sure, it's...

    True 1.5v AA and AAA batteries

    Yegads, yes, they definitely would put out 1.5V quite happily at a mini mag's ~300mA, which does smush typical alkalines down to about a 5 hour runtime (1500mAh, then?). But, um, wow... what kind of lamp life do you get out of that? I vaguely recall Mag saying "about 5 sets of batteries"...

    What flashlight do you keep in your vehicle?

    Pretty minimal, just a Thrunite Ti3 with an AAA Eneloop, and some backup alkalines that double for the tire pressure gauge, which takes two. I have a couple of Energizer Ultimate AAs in the ash tray and maybe a Sofirn SF10 in the glovebox. There are some ancient red LED blinkers with magnetic...

    True 1.5v AA and AAA batteries

    I guess they've improved. Good to know! The early EBLs I would never have run at 1A. I should do tests on the newer ones but, honestly, I don't care. I have no use for 1.5V LI AA at (sustained) high currents. Still, I'm curious. They are useful in motorized things. All those I've tested...

    True 1.5v AA and AAA batteries

    EBL and XTAR have newer versions that drop to a lower voltage (I have records but forget which) at the last 10% or so, for cases where a warning is important. I mostly use them in LED candles, so don't care. For radios, too much RFI/EMI. For flashlights, I'm not keen on the heat these generate...

    Store brand batteries or Energizers? - LED Flashlight

    Some recent informal alkaline testing on some off brands. 1 amp first discharge, two 200mA discharges, then a sum of those three. That was what I did in years past. For reference, in previous tests, major brands hit 1800-2000mAh in previous tests in 2010, 2014, 2021. Maha C9000. Back when...

    The Official Zebralight Thread .

    Assertion, not analysis. I'd bet I'm in the majority, if you count the ZL users who _aren't_ on this forum ;) But, who knows. Anyway, I'm happy to not have any double-click shut-off issues in G5 on any of the three new flashlight models (53n,65hi,700hi) that I bought.

    a what point do you stop collecting ?

    Most of the local mexican and burger/bar places have plates that were $10-12 now going for $13-16. I never order a soda or appetizer or anything else, so it's just that plus 7.5% NC tax and 15% tip. So anything under $16 is under $20. The nachos at one burger/bar just jumped from $11 to $14...

    The Official Zebralight Thread .

    So far no noticable issues in my 53ns, 65s, or the SC700HI that just arrived. I imagine the 65s are the missing-components version but that seems to only be significant at H1*, which I hardly use. No premature step-down or flickering. No double-click or mode-sequencing shutoffs - yet. "I'd...

    a what point do you stop collecting ?

    I'm with ya, when it comes to dinner _out_. Plate of nachos, water, tip, is too close to $20 vs $10 these days. I'd rather eat cheap and buy some gizmo.

    ZL SC53c N 14500 Issue

    For better or worse, I have to second this. The AA (esp N) is really not that bright, and the small 18650 model is really small. Running 14500 has been "overclocking" for quite a while, now. I'm doing it with one of my Ns but just because, hey, it's a hobby, I wanna have fun.
