Yamaha SPX50D Battery Replacement

I have an old Yamaha SPX50D effects unit that is giving me a Low
Battery message. Not surprising given it's age. The battery is the
typical CRxxxx disc type but the connectors as spot welded? on to it
covering up the battery part number. Does anyone know what battery
this takes? I've been searching to no avail.

These are the most comon types:

There are several variants, some with only 2 connectors, some with different
pin spacing etc. They solder onto the PCB, those spot welded connections
are part of the battery.

Most audio manufacturers use 3volt 2032 type lithium coin cells, this is
what you should be looking for.

If you really want to make sure you get a drop in replacement, get one from
Yamaha.

Thanks, I'll try a 2032. I'm not worried about it being a drop in
replacement. I'll make it "fit". I just want to be sure that I use
the correct battery.

Yamaha got back to me and indeed you are correct, it is a CR2032. They
gave me a part number to order from them for $6.66US. I'm going to put
a socket in while I'm there and just use a regular battery but it's nice
to know that they respond quickly and still support their older products.

Yours probably has the original battery. Solder in a new one, it will give
you at least another 5 years, if you think you will still be using it then.

AFAIK, CRxxyy batteries are 3V lithium types where ..

xx = diameter in mm
yy = thickness in 10ths of mm

For example, a CR2032 is a 3V lithium battery, 20mm in diameter and
3.2mm thick.
