    Dragon Record Problem or Just Me?

    Thanks so much Peter and Tomaao, your help cleared up my fog. I'm off and testing/recording now. Jay

    Dragon Record Problem or Just Me?

    Thanks Peter. 1) So only test results are recorded and not charge or refresh? 2)What's the difference between test and refresh? I know that I could just try each mode to see, but I'm lazy. The instructions you linked to are quite helpful for navigating the functions, but I'm also seeking...

    Dragon Record Problem or Just Me?

    Peter, I did read that but remain unclear about some procedural details. Three dashed lines appear after pressing the record/test button. 1) Does the record function only display results from the test mode or other functions too? As I mentioned, the unit had been recording some results...

    Dragon Record Problem or Just Me?

    How is the record mode activated? It had recorded results all on its own, but now I can't enter the record mode. Unfortunately, I misplaced the instructions, but they were poorly written, incomplete, and the print is way too small. Thanks for any help.

    Don’t do this in a restaurant. (When they reopen)

    My wife & I used to frequent a nice pub to meet friends, celebrate birthdays, and special occasions. The back bar was fully mirrored, with the liquor bottles lined up in front. Back when small, bright, LED strobe flashlights hit the scene, I tested mine by shining it on that mirror. For a...

    Does it matter what type of cable/charger you use for a flashlight charged via USB?

    I'm surprised to learn that some cables have such small gauge wire that 2 - 3 amps are too much. Jeez, the insulation must cost as much as the tiny wire.

    Battery Selection Question

    Greetings Cardnyl. Although a given LED may be specd for a certain average & maximum current, the actual current drawn from the battery depends on the particular flashlight. One flashlight brand may use a driver who's maximum current is higher or lower than a different brand, even when using...

    Hohm Tech Base 4 vs Vapcell S4+ vs XTAR VC4S

    I haven't used the repair mode yet. FYI: my first Dragon only lasted one charge cycle and froze up. I returned it and took a chance on another - so far so good. Often, electronics will fail when new or old. Generally, if it works for the first few weeks, the electronic stuff will usually...

    Replacement for BC-900 charger?

    Time for more research; I too was not aware of the Hohm Tech. I really like that Vapecell S4+ and hope it lasts.

    XTAR Dragon IR Test Question

    Yeah, i'd imagine it doesn't take much probe movement at those low values. The readings are always close and ballpark is fine, like you indicated, Peter.

    Using nimh in clocks and tempeature meter

    I've actually measured the cut-off voltage on electronic clocks and indoor/outdoor thermometers. They've pretty consistently quit at about 0.9V. While lithium AA & AAA cells don't have more capacity than alkies, they work much better for sub-zero temperatures, maintaining a greater, more...

    Hohm Tech Base 4 vs Vapcell S4+ vs XTAR VC4S

    I've had the Vapecell for a couple months and like the numerous features, flexibility, and independent channels, but it can't accept D cells unless you add a metal extension to the + terminal. I also have the XTAR Dragon and like the D size cell capability and suspect the separate leads for...

    XTAR Dragon IR Test Question

    Another questions is about fluctuating IR readings. With some cells the IR indication changes a little each time the display cycles between voltage & IR. Sometimes the IR goes down and then rises and the other way around. Other times the readout is stable.

    Charging Less Than Discharge?

    I was mistaken about the Maha because it will also indicate some cells have discharged more than a subsequent recharging. This is with older AA & AAA cells, I believe. I'm going to have to keep some records and not go by memory to see if this happens with only old cells. I'm noticing...

    XTAR Dragon IR Test Question

    When measuring the internal resistance of some cells, the display may briefly show a reading and then continue to have three dashed lines appear. I suspect some cells are out of range, but I'm not certain and don't know what that range might be. I'm assuming it may indicate a too high...

    Fenix E-16 Too Easy On

    That's the Olight I have too and haven't accidentally turned it on. I also like the LED battery level indicator in the button rather than flashes or ramping down of the main lamp. Its magnetic charging base and remembering the moon mode are two other features the Fenix & Acebeam lights lack...

    Fenix E-16 Too Easy On

    While I like almost everything about this light, I'm wondering if it's got a flaw that completely interferes with convenience of frequent use? Usually it's in moon or low mode so the switch has to be depressed several times before reaching turbo or strobe - but that's where it ends up so often...

    Solar Charger for Dusk/Dawn LED

    Yes, gilesa, that's probably the route I'll take. Thanks for posting.

    Charging Less Than Discharge?

    If you're discharging @ 2A the capacity indication should be real accurate because that's a good load. To maintain a cell's maximum capacity I think remembering that a low, ~0.2C or less (320mA for a 1600mAh cell), discharge rate will more completely drain them and ~ 1C for recharging. 2C...

    What are the Best rechargeable D Cell batteries in 2020 ?

    Nine years ago I bought 10 AccuEvolution LSD 10Ah NiMH D cells and 10 4.5Ah C size. Their 2% monthly discharge is accurate and they all are still within ~10 of original capacity. I'm quite surprised they've held up this well.
