    Powerex Maha MH-C9000 repair help?

    Thanks for the comments. I've had it open and looked around, but didn't see anything obvious like cracked traces or board areas which appeared to show excessive heat, so my suspicion is that it's a failed component. One of my units' slots failed at the very instant I put a battery in it to...

    Powerex Maha MH-C9000 repair help?

    Have three MH-C9000 chargers and the two oldest have developed one slot each that thinks there's a battery inserted (when there's not) as soon as it completes its power on self-test. Those slots then begin charging at 125 mA and show a small fraction of a volt which, of course, effectively...

    MH-C9000 repair help?

    I have an old charger that's well out of warranty which no longer works on slot 1 (the other 3 slots still work fine). The symptom is that slot 1 thinks there's a battery installed when there isn't and it's showing an input voltage of 0.04 volts which causes it to default to a charge current of...

    Reverse polarity protection?

    Are the Quark Tactical/Turbo lights protected against inserting the battery backwards? If you accidentally do that and then try to turn it on, will it just not come on, or will something be damaged? Thanks.

    Drop in for 6P with most throw?

    Tightest beam drop-in I have is a D26-LED 3-mode unit from LumensFactory. It's tighter than their single mode I also received and less than half the beamwidth of my M61. Don't know if it was the luck of the draw or whether they're all that tight, but it even has a slightly narrower hotspot at...

    TK40 flaw

    Only Powerex 2700's or Imedion 2100's in mine since day 1. No unscrewing the head to eliminate the small keep-alive current & no corrosion anywhere. Toss the alkalines.

    TK 40 Technical Problem

    The Fenix website has some videos showing how to clean & repair their lights. Given your symptoms, the main thing I'd check is the metal plate in the switch - make sure it's screwed down tight and not loose. There are some indentations in it you can use with needle nose pliers to make sure...

    source for Maha C-9000 AC adapter?

    I have two C-9000s and both power supplies appear identical to Paul's photo of his. They were bought several years apart and the newest is at least a year or two old, so maybe the wall wart design has changed since.

    Quark Battery Options

    Although the voltage determines where a light drops out of regulation, when all else is equal, the power contained in the batteries is a reasonable indicator of which cell(s) will go longer. The choices you suggest are AA = (1.2 x 2) x 2.7 AH vs. Li = 3.7 x 2.6 AH. The AAs = 6.5W vs. Li =...

    FourSevens "Self Defense" Light?

    Because of the small reflectors, you'll have difficulty finding Quark-sized lights that combine lumens & throw as well as the larger designs do, since both heat and small reflectors tend to work against you. If your definition of self-defense is being able to temporarily blind someone, the...

    Pila IBC - Charging to 4.11-4.12 - Thoughts?

    One side of my Pila IBC routinely terminates at 4.17 to 4.18V and the other usually shows 4.20 to 4.21V right after completion. These are 18650s I'm checking. The termination voltage does not appear to be battery related. The voltage value appears to be the charger itself (left side is always...

    AW 18650 goes bad....

    Thought I saw another post recently where someone's battery protection ckt had tripped and he couldn't get it charged until he figured out how to disable the protection. Think he put another battery in parallel with the shutdown one for a short period of time which got it reactivated enough...

    keychain attachment strength Maratac AAA vs ITP A3

    Don't have the Maratac, but do have the ITP on a keychain. I got one of Berkeley Point's more robust split rings plus the microclip they sell for easy attachment/deattachment. So far, so good. Tried their nanoclip first, which fit ok, but the little hinge piece popped out at some point and...
