In my case the glue was used to fix some wires on the bottom side of the PCB. It was the sort of stuff that crumbles when removing it.

It's probably hot melt glue. It's applied hot then hardens as it cools. That stuff tends to become crumbly over time as it dries out. After this much time, it most likely needs to be reapplied.

Just opened my MK-II now, and fortunately there was no leakage.

I changed the battery anyway, and the former battery was old enough to have the battery holder's top plastic retainer's impression on it's surface.

Just wanted to bump this thread as a warning. I've never in all my years seen a leaky lithium cr2032, well, until recently that is... For some reason, this thread inspired me to open my 8 new in box Asus TUSL2 motherboards and check the coin cell batts for grins. 7 were fine (dead as can be), 1 was not! A leaky maxell cr2032! I've never seen this happen until now! Needless to say, I spent some time pulling coin cell batteries off of my shelved mobos after that... 😲

So... As I am about to reassemble my office with varios gaming addons... the battery is NOT needed for game music playback only for advanced programming, right?

I have removed the battery from mine and notice no difference in gaming usage... the only change I saw was the "battery low!" message on the sc-55's boot up... since we are not using these units to compose music we don't care about custom settings/maps/whatever being stored on the unit 😊

Opened mine today and yes, the battery was starting to go. Thanks for the heads up!

Probably a silly question but do MT-32's have a battery?

Life? Don't talk to me about life.

No, but people came up with MT-32 modifications to add a battery, so you may wish to check if you believe the unit you have or are planning to buy is modded. If your unit is Sound Canvas compatible and has a display, it is almost certain to have a battery.

Just letting you know that the Roland SC-55ST doesn't have a battery inside.

While we're at it. Does anyone know how to open a Yamaha MU80 unit?

I removed a ton of screws but not closer to opening it.

Also what's a good source for these button batteries? Might buy a few in bulk.

I opened mine to clean it, IIRC you remove the screws and pull the faccia with the screen... kind of tight but that's how you get it open... it has a soldered CR-2032 battery inside, no holder
Places that sell/repair watches also stock CR-2032 batteries, else it's places that sell electronic equipment components around here.

Our local supermarket sells them 😀 Not cheap, but convenient.

Will try opening that unit again and check if the battery is ok. Thanks!

you remove the screws so the bottom cover is free, pull the screen/faccia a little so the bottom part can be removed and you are done!
