I hope someone here can help me. Ok, I bought this Chinese mp4 player last March on ebay. Here is a link, this is not the exact item# that I bought from, I can't go back that far, but it looks identical in every way:

Last week, for some unknown reason, my battery suddenly swelled up, pushing open the case around it, and of course I can't use my player. I'm hoping everything else is ok, and that I just need to replace the battery. However, I have NO IDEA what kind of battery I need. Since I can't bring up my original ad, I can't see the specs they listed on the battery (if any). There are absolutely no markings of any kind on the battery itself. In that manual the came with the player, all it says is "rechargeable 1.5v battery". But on the website I posted above, which looks to me to be the same player, it says "Rechargeable Li-ion battery" and "you can use NOKIA phone battery as its power if necessary or emergency use! Such as type of 6600 battery", but when I looked this up, it says it is 3.7v . So, I don't know if I really need a 1.5v or 3.7v or what. I've also emailed the seller in Hong Kong, but so far no reply. Can anyone help?
