My TK40 still has one of the best beams and tints of all my lights.

I love my TK40. It was a hit in my neighborhood on halloween. I had several people say "police issue, huh". Made me laugh. I carry a PD20 in my pocket at all times. I also have my Bug out Bag with me at all times (I travel weekly, and try to be as prepared as possible). My TK40 rides in it's original case with 8 "duraloops" inside, and 8 fresh "duraloops" in case I need to reload. I also carry 5 CR123's for the PD20. I don't currently carry a charger, but need to research if it's ok to recharge batteries with a power inveerter, which I do carry. In my opinion, the way our country is headed, I would rather have the ability to run readily available AA primaries other than some other exotic rechargeable battery. If worst case happens, then I can recharge my batteries as long as my engine runs and fuel is available. I can then get AA's if needed. I've not seen many places that sell many 123's other than department stores, and there are not a large amt. there. We're talking bad, bad situation. I believe if it does get that bad, a good light will be one of many good things to have.

I've had my eye on the TK-40 for quite a while, and this thread isn't helping matters. :naughty:
Are you guys charging the entire battery pack at once (and possibly even balance charging these things in some manner)? Or do you pull the cells from the holder and charge them individually? In addition to the Maha MH-C9000, I also have the 8-cell Maha MH-C808M, so charging them individually all at once wouldn't be a problem for me. But using a hobby charger to charge the whole pack at once would likely be more convenient.

I just got mine last week, and I've been removing the cells from the holder and charging them in an MH-C800S.
Yesterday I allowed it to operate in turbo mode until the beam was subjectively dimmer, then pulled the cells and measured their voltage under no load condition. This was a set of nearly new Eneloop knockoffs, and I measured voltages between 0.90 and 1.14v.
I'm guessing that I didn't overdischarge any of the cells by allowing the light to run down so far, but I also suspect it would be wisest to periodically measure capacities and ensure they're approximately matched, something I have yet to do with the 16 cells I've dedicated to the TK40. That's a little time consuming since I only have one C9000.
I love the light, though (my wife thinks I'm weird). The more I use it, the more I appreciate the beam. It's warmer than any of my other LED lights, and the profile somehow makes it feel effortless to see things. I generally actually use it at low or medium mostly, since the two highest output levels are too bright for closeup work.

I don't own a TK40, I do however own a MCE Modded KL6...2.5 hours on the M6 body:twothumbs
more than my needs for throw, mostly I rely on the MCE modded L4s, 17670s are by cup of tea:thumbsup:

i'm not too concerned about overdischarging one or more of the cells in my light. runtime in my book refers to the time a light would be putting out its full rated output anyway so i'll always recharge when i lose turbo mode. i also doubt my charger charges my cells with enough individual discrepancies for it to matter. oh, and i completely trust my eneloops :twothumbs

i initially bought the 4 pack for mine. the way i played with my light when i got it, i ran them down quite quickly. went ahead and bought 8 more. the difference in weight is noticeable with 8 cells but i'd rather have the option of running them in either 4 or 8 cells.
Yes, in the future I'll change out the cells at first sign of turbo falling off.
Before I put real Eneloops in, I wanted to get a feel for how easily cells could be damaged by callous usage of the light. And my conclusion is that standard care is all that is required.

what exactly is the brand of said eneloop knockoffs? are they close to the performance of the real thing? i've read of rebranded ones like the duraloops. are they the same thing? just one question about batteries 🙂

It drives me nuts that Fenix won't redesign the light to accomadate L91 batteries

what kind of AA/s? If NiMH, I think it would be 9-10 hours.
I though it was possible to run the TK40 on L91s, they just recommend that you don't due to the risk of
