Confirmed !
I still have the 1st battery in my Xpander,- since I buyed it new.
No leakage though,- and when I thought theres a replacement
necessary, Ive found out the old is full up to now.
Im sure it depends on usage of the Xpander/Matrix-12, if its
been switched on all day for a few hrs,- the battery holds your
patches for decades.

Hi Jeremy,
The RAM data ( patch/multi data)in the M12/Xpander is
battery backed. As
opposed to FLASH ROM which is common in more modern
designs. The only problem
with battery backed RAM is you have to replace the battery
every so often. It
offers a theoretically endless number of re-writes( Patch
Saves) .
The Lithium battery used in the M12/ Xpander is one of the
more durable and long
lasting batteriesI have ever seen.
I keep meaning to change mine but have not gotten around
to it yet. It's been
holding the patches fine since the late 1980's.
I have seenthe same model battery leak once from a piece
of test gear (not
musical instrument) manufactured in 1981. It did not spill
onto the board but
developed some kind of white crystals around it's case. It
stillworked fine but
I replaced it anyway.
You can get exact replacements from Digi-Key which pretty
much ships worldwide.
And I happen to know they have a several European
and far east distribution centers, if you need one right
away.
Best
Karl
