MVS MV1B/1C battery replacement

[Big_P Big_p]

Update, after a 24-hour charge on a brand new LiR2032 it was able to hold the bios settings 2 hours after powering off. Today, after 18 hours being powered off, the bios settings reset again.

I have another brand new LiR 2032 that I charged in the console for about 9 hours and removed and have been checking the voltage daily. It seems to sit at 3.77V which is the same as when it was pulled from the console immediately following the 9-hour charge.

Any thoughts?

Some people have had issues after replacing the battery with the mvs chewing through cr2023's. I wonder if maybe this is a similar thing. I haven't looked into it as my mv1b doesn't appear to have this issue but I am sure someone around here has.
