September 1, 2019 at 10:04 am #181611Hello, 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?

January 15, 2020 at 12:30 pm #182489Hello 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.
September 11, 2020 at 8:50 am #183919Well, my replacement batteries from AliExpress started to leak, they would neither recharge anymore nor power the ezbook at all.
I’ll need to find new replacement batteries, but this time I don’t want any chinese crap cell, I’ll look for japanese cells. Anyone’s got any source? Thank youSeptember 12, 2020 at 2:22 pm #183923I abandoned this machine quite a while ago. Even after getting the new batteries sorted it still always ended up being a hassle to use and I got tired of the frustration. I’m sorry to hear about your batteries, but it may be a sign to finally move on to something better.
September 21, 2020 at 1:37 pm #183980I don’t think it’s that bad, considering how cheap it was.
I’m giving it a new try with japanese cell batteries and see what happens. If I can’t sort it out with those, I’ll pass this to my mother, who only uses her computer at home, so she does not really even need batteries 😀October 4, 2020 at 1:52 pm #184050…where I can buy japanese cell battery ?
