Need help finding a battery for my RCA MP3 player

[SmilinDoug]

Over the years I have looked and looked for this battery. I'm hoping with all the help you guys give in here, maybe one of you might find this.

It is an RCA model M4208RD-B MP3 player. The battery part number is AE323436P. The output is 3.7V and 350mAh.

I know it's old but I hate seeing things go to waste. I even have a Sony Walkman that I got in Desert Sorm, and it still works! If any of you can find the battery for this I would be very grateful.

A quick google of that part number turned up quite a few things. With the actual example in hand, you should be able to find one?

It's my fault I didn't give the dimensions of the battery. That's the hard part. After three more hours of searching I found one in China. There are probably hundreds of these batteries, but I couldn't find the right size............until now. Thanks guys.
