my magic mouse 2 keep disconnecting

[shaktimage]

Hello, my magic mouse 2 suddenly stopped working. I have ran all posible test i could find online, i have tried with another mouse, another computer... Result: it is the magic mouse 2 that has a problem. I managed to have it connected, and it disconnect after 10 seconds... everytime, with both computers. I live on a sailboat so it could be a corrosion problem (salty air) ?
Any idea how to repair it? I am afraid to open it...

I don't know how to fix it but I am not sure it is a corrosion problem. I have a keyboard and trackpad that both keep disconnecting from an M1 iMac, so much so that I now keep them connected to the computer with a cable. For me it started a month or more ago.
