Roland Juno 60 Battery Replacement

[Groovenizer]

Hi-

My Juno 60 needs a new battery. I've heard about people doing a CR2032 battery holder mod (CMOS type).

But isn't the original JU-60 battery (CR-1/3N) a 3.6V? I thought CR2032's are 3V? Is that a problem? Has anyone done this mod and can give me the exact specs of battery I need... I'd really appreciate that.

Thanks in advance.

I'm not sure if it is the same on the 60 but I replaced the battery in a 106 recently with this one and it worked fine. (ordered from this exact link)

I've yet to do mine, but from everything I've read up on the subject theres no problems. Heck, some people have even done it with a double AA battery holder (wouldnt myself, but seems to say that 3v is fine!).

When you get round to changing it, take a few pics and i'll add it to the battery thread. thumbsup

Sure thing, will do.

Looks like this coin cell has the tabs soldered on. The reason for doing this mod was to not have to ever solder a battery in/out when it goes bad again in 20 years or so... (save my son some trouble...)

The Technologytransplant.com guy is selling the original battery for $9.99. Not sure which route to go...

Has anyone done this mod on a JU-60? Will the pins for a CR2032 holder align with the holes for the original battery?

how can you tell it's time for a new battery?
i just got a 60 and recently had an issue - when i go to a patch nothing sounds for a minute until i mess with various parameters, then it comes in, eventually - strange. dunno the problem but this thread reminded me to bring it up, if anyone has an idea... ive got EARS here in NY so i'll bring it to them eventually most likely

[fooddude]

I don't now if you want to do this:

But, I got dual AA holders at Radio Shack and installed em in my MPC 60, Juno 60 & TX81Z... Planning to do all my machines with 3V like this...maybe my MidiVerbII next. Just gotta make sure to replace/check every other year or so as they are more prone to leak than metal coin lithiums. But, it's been working perfect so far, and any future battery replacements will be super easy without taking out any PCB boards (like the MPC60 requires to even see the battery) as I velcroed the holders far away from PCB boards and highly visual once I swing open any covers/boxes.

Hard to say...low battery symptoms can manifest in many different ways. But most of the times some of the presets start to not sound at all or change to some random noise, bleeps, swooshes etc. My JU60 is pushing 30 years on the original battery. I'm sure most JU60 batteries are on its last leg by now....

hmm, sounds like that could be the culprit! i'll bring it in to EARS to have em take a look at some point .... =] any idea how much would be a fair price for them to take care of the battery (ballpark)? thanks!

I recently replaced the Battery in my Juno 60. I had it turned off for a while and when I went to turn it on all my presets were gone and nothing but garbled up patches.
I went to my Local Batteries Plus store and they had an exact replacement, they even soldered in the exact tabs that I needed. I then removed the old one on the Juno 60 and soldered the new one in, it was extremely easy.
here is a link, I know they have stores in San Diego

These batteries last for many years and there is really no need to put in a battery holder.

Not sure how much it would cost... but I did it recently on my Oberheim DMX and it took me maybe 10-15 mins to remove and solder the new battery in. I assume it's similar timewise. The JU60 is opened up quickly and the pcb boards are also fairly easy to take out. A normal repair shop charges around $100 labor per hour, so I'd say $30-40 maybe..

That's pretty much the problem I was having. New battery fixed it but you'll have to reload all your sounds.

Hardest part is just getting the old battery out cleanly. Gotta be quick with that solder sucker.

Cool well I'm going to take my 60 in to EARS here in NY to have it taken care of - wondering though, how have ya'll gone about backing up your patches?Mine came with an amazing set of patches (supposedly programmed by the son of Norm Sundholm of Sunn amplifiers).... Would suck to lose them!

[africantigercow]

word on the street is that covariance is doing an extensive midi/patch/functionality upgrade kit similar to the one he did for the jupiter4 for the Juno60. It sounds like it will be nullifying the need for a battery and upgrading the available patch spaces... (aswell as implementing full midi and adding lfos and all sorts of wonderful things).

The price he mentioned was pretty enticing too.

So is it ok to use a 3.6 volt, 950 mAh battery for the Juno 60?

I've done it a few times, it drops right in. While doing it, just say thanks it's not the stacked type like on a Korg or Ensoniq (which also frequently leak). A real pain...

The holder is nice, if in the future you do need to replace it - you can simply leave the Juno on while changing it and not worry about data loss.

How would a mod bypass the battery? Using Flash storage?

I have this mod on my 60--- it is a CR2032 button cell in a plastic holder. I can certify here that despite it being a 3.0 V cell (actually, I measure 3.2 V on my multimeter), it works brilliantly!

Ok, that's what I'll do. The CR2032 button cell in a plastic holder makes much more sense. However, I was referring to a purple, cylindrical battery with axial leads that is not a CR-1/3N (I should have provided this detail). The CR2032's I have are labeled 3 volts.

Hi,
does the replacement of the battery to a coin type (CR2032) need any change in the borad like in th Korg PolySix?

Not at all. It's a drop-in replacement.
