    Hello everyone, As I said, I ended up wiring the batteries as they came from the factory, and as seen in this thread. New wires where old ones were. Not as in seller’s picture. (Chances are it doesn’t actually matter. I am still waiting for someone with more knowledge to come and tell us the difference.) Also, to manually charge the batteries, You can use a regular 5V 2A charger (I used 5V 1.2A, did it gently, but perhaps took too long). I just cut and stripped the wires and tied them to the battery terminals best way I could. Checked regularly with the multimeter to see the voltage, stop at 4.3V. Check temperature regularly, if they get hot to touch, stop. You can read my previous messages for more details. It seems that I was the only one with this problem, though. Probably you should be fine if both cells come at the same voltage from the beginning. I didn’t check them when I first got them. That was my mistake, I think. Keep in mind as well that I am completely new to this (Bought a soldering iron and a multimeter to do this). I was asking for advice the whole time. Now I am just sharing my experience. Good Luck Paco

    Hi,

    I did everything Paco stated.

    1. Cells connected as described in the begining of this thread.

    2. Charged batteries for the first time for 6 hours.

    3. The discharging procedure runs 🙂 The battery bar shows as attached.

    4. So far works as charm. I will let u know the results after a week and a month.

    ps. One original battery I replaced works fine. Do you think I coud re-use it in the future?

    Tomek w przyszłości może ale do małych tabletów. Nie używana szybko starzeje się. Ty po kupnie tego EZbook czyli klona Kiano rozładowałeś go do końca? czy od razu go naładowałeś?

    Naładuj tego minilaptopa do końca, włącz go i zostaw go włączonego aż się rozładuje do końca żeby system ,,nauczył się,, kontroli baterii itd.

    Ok, so I have promising results now. First discharge was very good, almost 7 hours of mixed/light use. Second discharge, also good over 5 hours, with 2+ hours of playing a game (reaching the 9w TDP most of the time) also some video playback. Still a bit of battery left; goes to hibernate at 4% and after 15 minutes, computer can be turned on again at 7 to 14% (third time now). Chinese seller was right, it seems. After fully charging both cells manually (both to 4.3V), it now seems to be working as expected. Nothing was faulty. He proved as helpful as this thread. (To his advantage, of course). Also, I wired the batteries as instructed in this thread; new wires where old ones were. Not as in seller’s picture above. I will update if there is something new. But for now I am happy. Let’s see how long this lasts. Paco

    Nice!

    keep us posted

    I am afraid I don’t know how to help you. If it really is shot beyond repair, (I assume you checked batteries give voltage at the tabs where they are soldered, but no current at the cables that go to the computer, then best hope is to reflow all the points, maybe twist and bend the board a little bit or something, like Chupa suggested.) You might as well ask one of the chinese battery masters, maybe they have something to help you (In China, everything is possible). The one I talked to seemed to know his stuff. Worst case scenario, you have to buy one of those full battery units, or perhaps deal with GB (or whomever) support, if you can.

    Again, I am no expert. Hopefully someone else can give you better advice. Or somebody can just point you to the spare board. I didn’t know how to even look for it.

    Hi Paco, Online store link, pls.

    @Galen G.Cortes

    I am sure you are smart enough to figure it out on your own. Especially since you had the energy to ask for it three times.

    However, it is not just your fault that the useful messages get buried. Nobody with a problem like this should be expected to fully read 16 pages of a thread.

    There should be a better way to handle this. Sorry if I sounded a bit rude. Es sólo mi opinión.

    well , you do not read everything, you just skim and see where the good parts are.
    Often they start with Chupa.

    but if you want to create a wiki page about all the essential info, you are quite welcome to do so.
