    People it is simple, your battery cells are in a plastic frame covered  by a sticky plastic sticker.
    Remove the battery
    Carefully remove the plastic sticker so you can see the cells and the electronic.
    Often only one cell is damaged if the battery is newish.
    You can figure that out by measuring each cell after a full and a half charged state.
    Now you have the exact dimensions of a cell and can get a couple so you have a spare for the future.
    It is much easier than with the old notebooks where they liked to glue the cases shut.
    But after you cut them open it was easy to measure the bad ones and replace.

    REMEMBER YOU are the Jumper service technician, there is no one else.
    Try bring it into your local repair shop and hear them laugh…

    or, since it is a mac bugger clone, try an apple repair shop – not the ones with the big glass front and the half eaten fruit on top, but hey if you do that with a hidden camera it would make a good youtube clip

    I measured 6mm thickness. So that battery would fit. The problem is to solder new batteries on the original battery cable!

    what´s the problem?
    cut off the faulty battery close to the cable entering  the battery and solder the new on the old cables. Cut cables separate for safety, or cut cables together for surprise!
    Cut one cable 2cm shorter than the other, so they are not touching in the cut area.
    Don´t want to solder just strip 1 cm each and twist them good together and put electrical tape around.

    Hello
    follow this conversation with great interest
    I have the same problem with the battery of my ezbook 3 pro. I bought it in January in Geekbuying and the battery is almost dead. Its duration does not exceed 40 minutes. Geekbuying does not give me solution. They answer me nicely nothing more.
    I have located a spare part of the original battery, but there are no stocks.You can check this link:
    http://www.cdrtd.com/products/laptop-battery-for-jumper-3282122-2s-7-6v-4500mah-32-4wh.html

    I have opened the battery and it is composed of two parts and a small circuit, but there are no labels so we do not know its brand, model or features.
    I have measured the voltage: one of the parts marks 3.97V and the other 4.30V and the total output 8.27. This is very strange, since the outer adhesive plastic label indicates 7.6V.I add photos

    I have searched for aliexpress a similar battery, and I have found a similar one, but I am afraid that it will not serve or damage my laptop.

    Excuse me for my English, I help the google translator.

    Regards

    Hi Ngongut! You have very nicely described this and presented it in an image, everything looks just for replacing the cells, if the electronics are OK. many sites have a large selection of LIPo batteries of various strengths. I recommend that you select the cell’s approximate power of the original, while the cell of quite a bit of power will not be adequately charged. I have found these and they are all right, the price is about $ 10 per piece. https://telit.co.rs/industry-bateries/litium-polimer/li-polimer-3-dot-7v-3350mah-us3266116-sony or at amazon.com https://www.amazon.com/s/ ref = sr_pg_2? rh = n% 3A3760901% 2Cn% 3A15342811% 2Cn% 3A15745581% 2Cn% 3A10112773011% 2Ck% 3Alithium + polymer + battery & page = 2 & keywords = lithium + polymer + battery & ie = UTF8 & qid = 1525284392 just to mention it is necessary to remove electronics from some battery types, and use existing electronics.

    Be careful when dealing with li-po or li-ion batteries because they can be quite dangerous

    Hello to all,. I received my ezbook 3 pro on 09/03/2018 gearbest. How can I find out the version? the bios 05/12/2017 I have a problem with the battery !!! the battery charge only up to 82% Although the laptop is charging all night, in the morning the battery is 82%.

    I’m sorry for my english

    I had a somewhat similar problem.

    I can charge to 100% – the LED turns green which means full charge – I turn on laptop, indeed it says 100% – I turn off laptop, go away, come back a few hours later….suddenly it’s at 90% or something. Almost like it’s losing power while it’s off. Did you have this problem too????

    I contacted GB and they offer to repair it when I send it to them so far so good.

    As I live in Germany I don’t have to send it to China (and avoid all battery-parcel-delivery problems). Instead, I can send it to Alicante (Spain) and if they can’t fix or it breaks again I will get a replacement Jumper (hope that one would be a never version). I think this sounds like a fair deal.

    Has anyone else in Europe had the same offer? Was not able to find stuff around here.

    i’ve sent mine to spain on 11th june, now i wait for it to get back, already have german DHL tracking number that they use for EU prio shipping (TAX less), so it should be 1-2 weeks till i have it. don’t trust gearbest too much, they will help you till you have paypal buyer protection, after that you are on your own.
