    Hello, everyone. I have a Ezbook 3 pro with a slightly different battery from the template of this tutorial. A TH140A (Which instead of being retangulated is a square). I am with doubts as to the weld, because unlike the other batteries posted here in the Topic, the two parts are welded directly on the batteries as you can see in the image below. If the tutorial can be made for the model of my battery, I intend to buy the batteries to weld too, because my original battery are swollen.

    I also have this same battery, my battery last less than 5 min full charged.

    one side of the battery looks like it’s going to explode, i removed the battery and i don’t know what should i do with it, is it safe to disassemble it?

    Disconnect the battery and dispose of it in the bin, do not try and tamper with it as it will likely explode.  One of the two battery cells in my EZ book had swollen the same way and i replaced the battery.  The laptop will run off the power supply without a battery so you can use it that way safely and then order a replacement battery.

    I ordered the below, although they are not in stock any more.  Currently they are still working and do not appear to have swollen, but the discharge time is very inconsistent as sometimes they’ll be fine for a few hours and other they will drain after little usage (eg fully charged and then put the laptop to sleep/shutdown and there is very little power remaining when switched back on again).   At first they worked well, with long usage times, so not sure if they are failing or I didnt calibrate them properly when i first installed them.  Or maybe its something caused by the charger or a PCB component being poor quality.

    I would love to have another go at installing a replacement battery, if it would mean a fully reliable laptop again, as aside from that issue i like everything else about the laptop and its still working well for me.  Its just currently the battery life can be unpredictable and so i pretty much always plug in to the mains while using.

    Curious to hear how has anyone else found their laptop since replacing their batteries?

    Without soldering skills, I guess I’m left with a laptop that only works when plugged in 🙁

    Hello friend. I replaced the faulty batteries of my EZBook 3 Pro back in October or November 2018. I since make very light use of the laptop for my office work (light browsing, word, excel etc). Today, depending on the usage, the batteries could last up to 7 hours (usually it lasts about 6 1/2 hours)  with 25 – 30% screen brightness and battery saver on. I must mention that when I bought the batteries (8100 mAh), I also bought a new charger, because the original one is very bad. Concerning your problem with inconsistent battery drainage, this also happens with my batteries and has been happening since I bought them. When fully charged they drain quickly until they reach 85%, then the drainage is normal and then when the batteries reach 12-13% they drain quickly again. When the laptop is in sleep mode the batteries drain slowly most of the times. I should point out that I have no special knowledge of this kind of stuff and I don’t know why this happens.
