    Less for more$ = better???

    I don't know about the other brands of rechargeable D, but the Energizers are nothing more than an AA cell inside a big empty can. :thumbsdow

    NiMh AA self discharge comparison

    Test is not over, but we already have a clear looser. Somehow I mistakenly got capacitors disguised as AA batteries. :ironic:

    There's a New Production World Champ - 6800 lumens 70W

    Maybe you can start up a group buy, that's how I got my X990 back in the day for $200. (You couldn't touch one for under $500 before that) They already had a US distributor but I went around them and their markup directly to Taiwan and got me and 20 other CPFers a great deal. In response the US...

    Old timer with newbie Mag questions...

    Kinda. What is the difference, exactly? Those are higher output versions? I'm a little confused with these new quad die emitters - each die can be wired in series or parallel, is that correct? Basically I'd like to get around 2 hours run time out of a 7.2v, 5Ah pack, and I want as much light...

    Are Duraloops and Eneloops the same thing?

    If the batteries say "made in Japan" and have a white top they are Eneloops. I have yet to see any of the non eneloops come through since they updated the wrapper last year. Even though they are the same battery, it is not a good idea to mix them. Batteries are best matched when they come from...

    F size lithium ion?

    Hmmm...I understand that a mystical 2D size, 10Ah, 3.7v lithium ion would be dangerous if used improperly. But would that be more dangerous than a 5Ah, 7.2v pack li-ion that is readily available? It may be worth going with the F size LiFe battery for safety reasons. I doubt that Saft cells are...

    F size lithium ion?

    I would love it if somebody made a 2D size lithium ion cell, around 10Ah/3.7V for a Maglite, but I don't think such a thing exists. (right?!) The next best thing should be an "F" (long D) cell. Batteryspace sells LiFe "F" cells, but they're only 4.5Ah. Does anybody sell regular lithium ion "F"...

    Old timer with newbie Mag questions...

    I feel the need to mod a 2D Mag up to today's standards. It's been a long time since I kept up on any of this stuff, and now I'm totally confused on what parts I'll need. I *think* I want to use a P7 emitter at about 12 watts. I want to power it with 2 D size (unprotected) lithium ions. I'll be...

    There's a New Production World Champ - 6800 lumens 70W

    That's a chinese wholesale company you posted. They do not sell to the public. The only way a company like that will sell you one is if you ask for a "sample", otherwise, it's 10 or 100 lights minimum and they want all your business info.

    NiMh AA self discharge comparison

    A surprise from the Energizer 2300's...exactly what I wanted to do this test for. :thumbsup:

    HID lumen maintainence?

    Huh. I guess I'll wait until next time I have to rebuild the battery packs to replace it. :laughing: I do (did) usually run it for an hour + at a time, for two hours a day almost every day for a year. I knew there was a break in period for the bulb but I thought it was just a hand full of hours....

    HID lumen maintainence?

    The original 35w bulb in my X990 has enough hours on it to kill 3 NiMh packs. (at roughly an hour per battery, 300 charges till death, that's probably around 900 or so hours on the bulb) It still works, but I'm wondering what the lumen maintainence is like in bulbs like these? I understand with...

    NiMh AA self discharge comparison

    I was just doing this test for myself but I thought you guys would be interested in the results. I have several different brands of new NiMh AA batteries that I charged 30 days ago. First they got 5 cycles to break them in. Now I am using my BC700 to test their capacity @ 350ma. They have been...

    Problem with Sanyo 2700 NiMH

    I have had similar problems with Duracell 2650 batteries, which I believe are Sanyos. Out of several hundred samples, at least half of them won't hold a charge for a week. I'd be willing to bet a lot this is why all the major MFGs are going back down to lower capacity batteries. 2700mah is...

    HID shock resistance

    Well, this is what my X990 looks like after it hit the ground: The lens was a pretty substantial peice of glass, however I continued using it many hours after the lens broke and I finally wore out my batteries. The bulb is still good...I need a new lens, reflector, and battery packs...but not a...
