Proceed CD Library

I have the Controller for it but no batteries and strange as it may seem, no one can help me figure out what batteries it needs. Without the batteries the unit will not operate. Any thoughts, beside junking this thing? I would love to have it up and operating for nostalgia mostly.

Someone must still own one of these and can help me out I hope.

The Controller allows you to access the CD’s to play or store them. Without it you can not do anything. There are no controls on the actual player itself. I think it might have been a custom or obscure battery, I tried using some common ones but they did not fit. I am hoping someone still owns one and can help me with this.

The Harmon group told me that the only info they have about the batteries are as follows:
4.85V 1/2C Cell Array Battery

Does this make sense to anyone?

Pyramid Audio in Austin, Texas told me to call Battery Plus which tried but could not help also. Both places were very nice to me though.

I am hoping I am not the only one who owns one of these, surly someone else does and can help me out with this silly battery problem. Does someone know anyone who has one or have you seen an ad for a Proceed CD Library for sale that I could ask the owner? 
Many thanks!

Thanks. The 1/2 C size Diameter is correct, fits great but it needs a total length of between 4 3/4 and 5" as it has a collapsable spring screwing in the top. I think I would need your four batteries for 4inches plus some tin foil folded up (on the negative end) to make up the difference. Does anyone think this would work?

I am thinking you might be right about the battery pack being in-house. You would think that at $13000 1990 dollars someone would still have the unit and battery pack lying around somewhere. I can not be the only human on the planet with this player. At least I hope not.

I tried that and they were quite kind but could not provide the answer. I keep looking for someone to be selling one so as to ask what I could do. If anyone sees an add please let me know.
Again thanks to everyone trying to help!

That sounds like it would work but what kind of a conductive spacer can I make or buy that you think would work best? I probably need about 3/4" in length to fill the gap, width is perfect. I am connecting them in series not in parallel so as you say that would give me 4.8 Volts.

I am just afraid if I do not find the answer a piece of audio history will fall by the wayside, let's not give up.
Thank you everyone!!

Thanks!! But does he have a Proceed CD Library? It has a very specific controller.

I did email him and he was great. He did play with one once but did not know about the batteries. Very nice of him to answer me though. I am still hoping that someone still has one tucked away somewhere and can help. Even if it is just the controller with some older batteries in it.

Four of those 1/2C batteries would be ok in width but only 4" in height and I need 4 3/4" maybe 5. Four would put the voltage at 4.8v for each side but five would put the voltage at 6v, too high I think. Also am wondering if 4.85v is for total of both sides of the controller battery departments or just for each side which I think it is? The controller needs battery packs one for each side. Check out the old Stereophile review, it is still online. Just google Proceed CD Library. Not sure and hard to get info on this. My best bet would be to find someone with one of these units somewhere and do it right. I cannot be the only one in the world with this unit, can I?

They made the Proceed CD Library from 1991-1995.  As for its value in todays market I just want it for a conversation piece and of course hoping it will still sound good. Wow, $400, to bad you did not snag it. Do you think that shop might know the batteries or perhaps their customer still owns it?

I do not know anyone who had one nor can I find anyone on the internet discussing this older piece. Still I have not given up yet. I am thinking of calling a Rowe repair shop as they made the CD changer part but not I think the Communicator with the batteries I need to find out about. Still, at this point worth a try. 

 they have no info on something that old

Tried that also, no luck, but I have not yet given up will keep you updated.

Still working on this. I put in three C cell batteries which total the right volts but not the right amps (I think, as I dont know what amps it needs) as the warning on the controller says "batteries need recharging". They are new good batteries ( I tested) but the controller wont let me get into the setup. They stick out a bit as they are too tall but with some tin foil wrapped around and touching the sides and top, help together with tape, at lease the controller turned on and I now know that will work. Any suggestions?
