[sdiy] Oberheim Matrix 6 ---- 3.6v Lithium battery replacement.. or not ?

[Jean-Pierre Desrochers]

Hi all,

A friend of mine brought me a working Oberheim Matrix 6 keyboard
that he was worried about the inner memory lithium battery (BR2032)
being about to die.. and to replace it.

Well after a quick check the battery was still in pretty good physical condition (no leakage)




and was showing a strong 3.23v on its terminal (AC unconnected)

So.. In this situation I’m wondering if this lithium cell should be replaced or not.
I know this keyboard is at least 30-40 years old and many of the coin
batteries of these vintage keyboards need to be replaced, but..
And on replacement I thought about soldering a coin battery socket
on the PCB pads BUT the battery placement on the PCB
is very close to some IC’s as shown on the picture and
would need the socket to be raised a little to avoid these IC’s.. I don’t like that.
I could also buy a coin battery with PCB legs too like this one
but again, replacement or not ?



I don’t know the year of manufacture of this Matrix but here are
the serial number and BIOS number.

SN: 7622661

BIOS: M6R 2.13

 

Your opinions are very welcomed.
Cheers !
Jean-Pierre
