Replace the battery


I am thinking of buying a secondhand unit - Model . mu 01 made in 2015 was bought in 2016.

Can the battery be replaced?

If so are there instructions on how to do this?

Many thanks


Looking at some teardown shots on the web, the battery is soldered to the board, so not easily replaced by those unfamiliar with soldering.


Thank-you Mattmind for that information.
