Replacing Batteries in Old Modules - HELP

Recommended Posts

I'm tring to dust off some of my very old modules. I have to replace batteries in several. I did it already in my Korg Mr3. I have an old Proteus 1 and an Ensoniq SQr. The Proteus looks like a more complex operation. Opening it up was a challenge as it has now screws. A relief in a sense since the SQrs top two screws are stripped. Can't get that one out without a drill I suppose. Tips anyone? Anyway in the Proteus theres a large Lithium battery BR-2/3A 3v held snuggly with a tie and maybe soldered in. Anyone have any experience with this want to give me a tip?

 

I've used a soldering gun and built kits in the distant past but I'm no electrician. My hands are best used for playing the guitar, but I resent sending this to repair and spending $100+ for replacing a battery. Plus these are old modules. I don't want to spend any more money on them.

All the best,

On getting the stripped screws out: I've fount that if you put upward pressure on the case (like your trying to take it off once the screws are out) while simultaneously unscrewing it sometimes allows the screws to catch and then you can get them out.
Setup: Korg Kronos 61, Roland XV-88, Korg Triton-Rack, Motif-Rack, Korg N1r, Alesis QSR, Roland M-GS64 Yamaha KX-88, KX76, Roland Super-JX, E-Mu Longboard 61, Kawai K1II, Kawai K4.

my suggestion - unless you know how to deal with the stuff, don't do it! i tried to change the battery in my ensoniq sq-2 and successfully screwed the memory so it won't remember anything programmed.

You're just gonna have to get in there and see what you've got. I had a battery go out on an old Roland module once when I was in Korea of all places. Opened it up and it took one of those little disk batteries that looks like a quarter. The PX just happened to have one! Lucked out.

 

Also replaced a Yamaha battery once. It was soldered to the circut board. Had to carefully unsolder the old one and put in the new which was only available from Yammy and quite expensive for a friggin' battery. Worked just fine tho.
