I recommend getting some of those PCBs in the link above ordered and installing a battery holder in its place.

old! The old Sanyo CR2032 coin cell looked fine from the top (+) side, <br>
measured 3.295v and hadn't shown any battery warning message on the synth's <br>
display. In fact it's terminal voltage was higher than my brand new <br>
Panasonic CR2032s that both measured 3.278v. However, when I de-soldered it <br>
the hidden underside was covered in tiny crystals and green crud (>.<) <br>
Looks like I got there just in time! So, don't wait for the low battery <br>
message, or visible corrosion, and don't wait for 40 years before changing <br>
it!!!<br>
<br>
For anyone with an Alpha or MKS-50 there's an excellent step-by-step guide <br>
