    it's a bullshit manual.
    i have many such lights, they all sold for use with 3x alkaline non-rechargeable cells as a backup to the 18650.

    btw, do they have a usb port on the light or a barrel-jack?
    the jack type have no charger or protection circuit in them!!!


    btw, you wont get far with NiMH cells - even the very best are only going to give you 900mAH

      It's USB. Yeah, I too find it a bit misleading that it says it can use either of the two, which lets your average Joe who knows nothing about electronics to just roll with it and throw in there whatever batts he comes across....

        It might be interesting to see what in this light because STJ is right I have seen some of this crap before

        I bought one a while back and the battery that came with it
        Had some milliamperes claim but came no where near it was way off I just tossed the battery

          currently for the hll of it, I have a 6-cell SLA hooked up in parallel to a 10-cell NiMH and charging CCCV at 13.8V.

          Big tradeoff here, see it? Alas, it's difficult to use both packs at the same time...

            Replacing the WiFi module on a vacuum cleaner iROBOT i7
            by AlexVG
            Hi,
            I have had an iROBOT i7 with a camera error (error 68) version REV M, year 2018.

            I bought a liquid damaged Mainboard with WiFi module, from the same vacuum cleaner, but a different year and a different version (REV G).
            (This board does not respond, only the LEDs light up in a circle.
            The liquid damage is catastrophic and restoration is impractical).
            (I bought this board to get the WiFi module and camera).

            The boards are completely different in the installation of elements, even the connector for the WiFi module is different.

            If...

            The ups takes 3 x 18650 cells in Parallel - Can I extend to 6 x 18650 safely?
            by Chaks
            I need help to extend the runtime of the ups board (see attached image).
            This is ups board for a CM4 which has 3 18650 cells in parallel. Can I extend the 3 cells to 6 cells for a longer runtime? by soldering a wire to each of the battery terminal and connecting it to a separate battery case with 6 cells.
            Thanks and kind regards,

            Hoover FM216LI cordless vacuum refuses to charge
            by flat-earther
            I have a Hoover FM216LI cordless vacuum which isn't charging its internal battery.

            I opened up the unit, and it has 6x Samsung ICR18650-22P cells connected in series.
            5 cells were at about 3.3-3.1V. one was at 2.4V, so I assumed this cell was bad that's why the vacuum wasn't charging so I replaced it with another 18650, but after that the problem still persists, the vacuum turns on a bit and then cuts out since the batteries are empty.

            So I think the over discharged battery wasn't the culprit, it was a symptom of the unit not being able to charge its batteries....

            Bosch 12V and 18V chargers modification
            by Petr0x
            Hi, I would like to share with you small modification to your Bosch tool 12V and 18V chargers.

            You can use it for almost all Bosch chargers what I have seen, for example part numbers GAL 18V-20, GAL 18V-40, GAL 1880, GAL 18V-160, AL 1820, AL1115CV, AL1130CV.

            Bosch (today also other brands using the same system like Wurth, Fein) does not care if you destroy your batteries, because they can sell you new ones. So the marketing is telling you only about speed of the charging, so you will not wait for your batteries to charge too long. Me as a customer want the tools and batteries...

            ZD-915 vacuum pump motor mount service alert
            by sam_sam_sam
            If you have this Desoldering Gun Station there is something you should be aware of the two screws that hold the motor to mounting for pump can come loose and make raddling noise

            One note this unit has been repaired already once because of switching power supply regulator ic chip failure
            Now this with the vacuum motor mounting issue yes I give this Desoldering station a very hard work out and use about every weekend to do some type of project

            The fix is taking the vacuum pump assembly out and take the metal cover off and you will see the two screws on it
