Surface Book Keyboard battery present BUT NOT ON USE

[ahmtcvdr]

Hello,

Recently I changed keyboard battery of my surface book with performance base model. After replacement the battery is present on screen and battery reports. But it shows all the time 93%. Also I realized the device only using tablet battery and after it finished it turn off. Guarentee already finished and I don`t have any microsoft store in my country. So I need to fix myself. How can I fix this issue ?
