My Huawei Tablet dtab (Docomo d-02H) has been in use for years, but now it only can handle work in short time, because the battery problem.
I checked with AccuBattery App to detect battery health, and the tablet has estimated capacity 928mAh, so I decided to replace it with a better capacity battery.

In the local online marketplace, I found a used cell battery from Samsung Tablet (GT-P3100) and planning to use it to replace my tablet battery.
I moved the original battery protection board & connector from the Huawei tablet battery to Samsung battery cell.

After soldering the battery protection board to the Samsung battery cell, then I tried it on the Huawei Tablet.
To find out the current battery capacity installed, I deleted the old data in the Accubattery app.
After several battery charge and discharge process, in the application detected the estimated battery is 3278mAh.
It's working. Battery capacity is now increasing. My Huawei tablet now has enough battery capacity, it can run the Tablet in a few hours.
