Anyone know where I might find a rechargeable battery for a Sony TCD-D3 DAT Walkman?

It seems, that they are not made anymore. I tried to get one myself some time ago. On a forum (http://www.hifi-forum.de/viewthread-29-8563.html) someone gave this solution:

"First, the battery (6V, 1.5Amp)

Typeno. = BP-D3
Sony Partno. = 1-528-334-11 (AEP, EA)
Sony Partn0. = 1-528-333-11 (US, CND, UK, E, AUS)

You are right, the batterypack is not supplied any more.
HOWEVER, most custom batterypacks are just custom on the OUT-side. IN-side they consist of standard AA-, C- or even D-cells. In your case they are NiCD cells I believe, because of the age. In most cases they could just be replaced with modern NiMH cells of the same physical size. The gain will be higher yield of performance. The existing pack runs around 2 hours. If replaced with NiMH expect closer to 3- 3.5 hours.
So, you should OPEN the old pack in some way. Carefully, because it doesn't live shielded in some battery compartment but is part of the recorders exterior and you don't want scars on your vintage jewel
If it's clearly seen the pack is made by 2 halves, just glued together, I usually put it in a wise and SQUEEZE it. The plastic will snap open along the glued edges in some weaker places and the rest can be done carefully by hand with a knife and a broad screwdriver.
If it's not made out by 2 halves, but looks moulded into one piece, it's going to be harder. Cutting/sawing in the only way and that's going to leave scars. Still, you must open it.
Inside you'll find the cells, connected in series. 5 of them, most likely (5 x 1,2V = 6V). Measure length and diameter and try to find what's available within measurements. If you have to choose smaller cells, don't worry. They have at least the same capacity as the originals. The new cells should be bought with metal strips already at each end for easy soldering. Before final re-assembly/glueing, try to just keep things in place by wrapping a couple of rubber-bands around the pack. Does it charge? does it run for at least a couple of hours on a charge? If so, it's time to do the final re-assembly."

A different solution might be an extrenal battery pack.

Let us know, how you get on.

Thanks inchadney. The problem is I am not searching because my battery's gone out, but I bought a unit at an estate sale and, while I have the recharger/DC unit, the actual battery, casing and all, was not part of the purchase. I need the latter before I can create an alternate solution, I believe.

Well, it seems, that the only solution will be an external batterypack, as I believe it is pretty hard to get the actual battery for it.

Visitor14,

I tried eBay and came up empty handed so far. I search on the battery's model # and part # and for the part # of the actual DAT player, and no. Can you give me a clue as to what search you use or what seller has these?

Well, there is this one: http://cgi.ebay.de/BP-D3-Rechargeable-Battery-Pack-Sony-DAT-TCD-D3-6V-1300_W0QQitemZ220366661422QQihZ012QQcategoryZ82046QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
