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.

Hello @kieran. I bought the 8100 mAh batteries from Aliexpress and I installed them in October 2018. Since then I had no problems, but I make light use of my EZBOOK 3 PRO (Word, Excel, light browsing, 30% screen brightness, battery saver on). At the moment depending on the usage the batteries will last between 5.30 and 6 hours. The only thing that I faced is the fact that the batteries from the very start of their usage lose 20% of their power in the first half an hour and then everything is normal. For me it is worth buying these batteries, because the laptop has no other important fault, except the one with the batteries.

Hello guys, Paco how do you charge the batteries manually? I want to mention that when I soldered the batteries I did it exactly as they were soldered from the factory and not as the picture of the seller implies. Here is a picture of my battery situation today.

Hello, first of all I want to thank everyone here for their help and participation. I bought a Jumper EZBook 3 Pro in January 2018 and it had the same problem with the battery of course. I replaced the batteries in May with two less powerful ones that a friend gave me and at first I used to get two hours of usage with medium settings. Three months later the usage time had been reduced to half an hour and it even took 10 minutes to discharge from 100% to 50%, so I bought two 8100 mah batteries from Aliexpress and put them on my laptop four weeks ago. Now I can get up to five hours of medium usage from them with 50% screen brightness, better battery settings, light browsing, youtube and Microsoft Office and it is more if I set the screen brightness 25% and battery saver on. I have noticed though that sometimes the battery takes 15 minutes to discharge from 100% to 80% and after that the discharge time is normal. Considering that the latter, with the fast battery drainage, has happened twice to me, it seems that it might not be the batteries fault, but something else. I have no knowledge of electronics and I just wanted to report my experience with the battery problem, with the exception of which my laptop has been great so far. Also excuse my English, because it is not my native language.
