Just opened my MU80, and battery is soldered definitely soldered or fixed in some other way i can't understand. Anyway, it's not a regular CR2032. At least mine is very clean and not leaky.

^ it's just a pcb mount 2032... mine was very clean as well so I just left it

Is this problem also with MT-32 and CM-32L?

I have to check mine soon as possible.

Thanks for this info I just opened my SC-55 and the battery was slowly leaking.

Robin4: MT-32 doesn't have any battery inside. I did open the box to make sure that I don't have same situation like with SC-55.
now i'm going to check the MU-80 😉

About the CR-2032 batteries - you can also get them at camera selling shops too.

There are Chinese sellers who have them in bulk packs on ebay for only pennies per battery. A 100 pack would probably be a good investment for almost anyone who has a lot of old hardware lying around that needs at least one of these.

^ yeah and next thing you know they start leaking in a couple of years... no thanks 🤣
batteries in one of the things you don't want to cheap out ;P

I got two packs of four Energizer branded ones.

Quite pricey relatively speaking, but what can you do 😀

Will swap the batteries later today although none have been leaking.

which midi modules have batteries?

i have a roland CM-300 and a roland CM-32L

They don't have batteries.

I removed the battery from my SC-55mkii a long time ago -- because I put the box into cold storage.
I took it out of storage, and found out the manual doesn't list the internal battery model, only the remote.
Is the SC-55mkii a CR2032, or something else?

THANKS!!!

Also... I just joined this site. I have to say, as a colour blind person, the question to verify the colour of the background or foreground REALLY blows

Second questions... is it positive side up? I haven't opened the box yet, so i don't know if it lists the battery type or the polarity on the board.

Hi and welcome!
IIRC yes, the mk2 has a CR2032 battery and the positive side is up, you should be able to read the markings on the battery once installed

Yes, it's a CR2032 battery. I just changed mine (MKII).

awesome! Thanks!!

Another SC-55 mk1, another leaking battery... 😲 😲 😲

Nice save! These button batteries seem to die more gracefully than the old barrel things, which spew acid far and wide. Still not a good look though.

What do you guys do with old batteries? I've been vaguely aware that they shouldn't be thrown into the bin, but that's exactly where I've put them all my life. I've done a bit of research and discovered that there are numerous places near where I live which accept dead batteries to be recycled, who knew?

How do I remove the battery from the SC-55 MKII?

You may need to use a gripping tool in case your fingers cannot grip it sufficiently. 😀

I've always hoped to acquire one of these and do a polymer recap plus bipolars and films for audio. Someday...
