Space Grey Magic Mouse 2 Battery Replacement Apple's official service is not available.
I am a resident of Daejeon, Korea.
The battery of the Space Gray color Magic Mouse 2 that I used was not charged. So, I visited the Apple Official Center located in Daejeon.
However, it is not possible to apply because there is no "mouse battery replacement" item in the center's operation computer. Apple's official website https://support.apple.com/ko-kr/mac/repair/service clearly states that 3535,000 will be replaced for a fee.
