    Just recieved my Maha MH C9000 today! But I need some beginners help......

    I wouldn't worry about them. They appear to be good cells with excellent capacity. I am pretty sure that I have "gone overboard" with my attempts to match cells. As I understand it, high variation is really only a true issue in devices/applications where one (or more) cells can get fully...

    I can't see me (or anyone else?) arguing too strongly against what Maha recommends... As I have already pointed out, I "made the mistake" of using lower current, but so far that seems to work fine too. I think "very warm" and "almost hot" are far too subjective. I think you will need to...

    Just recieved my Maha MH C9000 today! But I need some beginners help......

    There has been considerably discussion on this forum about Slot 1 of the C9000. It does tend to consistently give different (lower?) readings than might otherwise be expected. I don't think anyone has ever successfully explained why. Remember, however, that this device is far from being a...

    Maha MH-C9000 SUPPORT / FAQ - continuation

    Thanks for explaining this! I finally understand why it charges for 16 hours. (This may be explained somewhere else in this thread, or on this forum... I cant say that I recall ever reading it before. If I ever did it was a long time ago.) In any case, what you say makes great sense to me...

    Maha MH-C9000 SUPPORT / FAQ - continuation

    I believe you can assume that your cells are completely "topped off" after the Break-In mode. As I recall, it charges at 0.1 C (or 10% of cell capacity) for 16 hours. I believe in most situations, your cell would be fully charged under these conditions in about 10 hours (!0% x 10 = 100%). So...

    I think this has been made clear, but just in case... It is not actual voltage that is being discussed. It is a quick flash on the screen, when the cell is first inserted that shows a "voltage" number. That first flash of the "voltage" number is not the actual starting voltage of the cell...

    "Great minds think alike..." and all that. One other thing I did forget to mention: I am not entirely certain of this, but I have read several times on our forum that the C9000 flashes some kind of cell impedance or "internal resistance" value, once, and only once; and only very briefly when...

    Well, there really isn't much, I don't think. As I said, I don't even have my manual handy anymore. I just "use" my C9000 these days. But, let me start at the beginning for you. There are five things that you can do with your C9000 (I am not listing them in the same order as the selection...

    I don't have my manual handy, but this doesn't sound right. (Perhaps, I am not understanding what you you are saying.) I believe that the first thing that the C9000 does in "Analysis" mode (Refresh/Analyze) is charge the cell. So, I do not believe that they would recommend that you charge...

    Let me be the first to congratulate you on what I believe is an excellent purchase! I have been using my Maha C9000 for nearly 3 years, and I have found it to be a wonderful product. I am not anywhere near the "Maha C9000 Expert" of this forum, but let me tell you about my experience. I have...

    Best D Cell Rechargeable Batteries

    Interesting, I have never experienced that (yet). Thanks for the warning. I hate to damage my Eneloop wrappers. Does the damage occur on the ends? (Some chargers and some devices tend to do that if you are not careful, I have noticed.) Have you found any simple solutions? Perhaps you can...

    Best D Cell Rechargeable Batteries

    I find that 3 AA cell to 1 D cell adapters, something like these, work great: http://www.ebay.com/itm/4-x-Parallel-Battery-Adapter-Holder-1-5V-Case-Box-Converter-3-AA-to-1-D-Size-/121534973216?hash=item1c4c0c8520:m:mr4uDgYzgVbR7vn5z8pXSJg As for batteries, I find that 3 x AA Eneloop "Black"...

    Getting ready to buy my first rechargeables, very confused

    Thank you very much HKJ for your post. As usual, I learned something new. Balog, I think you already know of HKJ, since you refer to his battery reviews. But, let me assure you that we have received the "final word" from one of the true experts, and we should be honored!

    I assure you, "someone" knows. If necessary, try posting that specific question... perhaps in the LED flashlight section of this forum.

    Getting ready to buy my first rechargeables, very confused

    So, this is all part of what makes understanding Li-Ion cells and flashlights so "interesting." As I understand it, the answer to this question depends entirely upon the flashlight. More to the point, it depends on the type of "driver" circuit used to power the LED. Some drivers take high...
