    I added new information about the dispute at the end of the first post.

    I took a chance and ordered this battery.
    He arrived 2 days ago. Unfortunately out of order.
    When connected to charging, it shows the full capacity almost immediately (all 3 LEDs are on) and the voltage at the terminals is 9.4V.
    After disconnecting the cable, the voltage drops to 0V in 3-4 seconds :cry:

    I have never made a dispute on Ali before. Question - should I first confirm receipt of the package and then set up a dispute or set it up right away?

    What's on the other end of that cable?

    At the other end of the cable is a USB charger :)

    It's no wonder it doesn't work. Current consumption too high.

    I don't think we understand each other.
    I connect the charger with a micro-USB cable to the battery to charge it. The charge indicator shows that the battery is full and there is 9.4V on its terminals. And now, when I disconnect the micro-USB cable from the battery, I can see on the meter how the voltage drops to 0V.
    Aku is not burdened with anything. Well, maybe except the meter :cunning:

    Well, we didn't really understand each other. Looks like an internal short circuit.

    And does this "battery" need some load for it to work?

    Probably not. I put it in the pyrometer and it didn't work ...

    Tell me, colleagues, what to do with this dispute - to put it on before or after confirming receipt of the parcel?

    Set up a dispute up to 6 days before the seller's protection date.
    Better to open a dispute before confirming the goods you've received.

    Thanks for the advice.

    I have one last question - in my case should I choose "Refund Only" or "Return Goods"?

    Refund only.

Topic summary

The discussion revolves around the testing and performance of a Chinese 9V rechargeable battery (6F22) with a built-in USB charging feature. Users share their experiences, noting that while the battery can be charged via a micro USB, its actual output voltage is lower than the standard 9V, typically around 8.4V. Several participants mention using the battery in multimeters, highlighting its suitability for low-current applications. Concerns are raised about the battery's capacity, with some users reporting discrepancies between the advertised and actual performance. The conversation also touches on the internal structure of the battery, suggesting it contains two lithium-ion cells in series without a boost converter, which affects its voltage stability under load. Issues with defective units are discussed, including one user experiencing a rapid voltage drop to 0V after charging. The community provides advice on handling disputes with sellers regarding faulty products.
