Battery for Rio Karma

The battery for my Rio Karma has failed. It still holds a charge and will work in the player, but it is now swollen to the point where it has forced the Karma's case open. I had to take out the screws and open the case to prevent damage.

Does anyone know of a source for a replacement battery?

Have you tried eBay?

Excellent! Not only are there Rio Karma batteries listed, but that also provides me with the part number DY004 so I can look in all sorts of places.

Thanks!

I replaced the battery in my Karma with a 1st gen iPhone one - it's a bit smaller, physically, but actually higher capacity
