Battery for MP4 player

[JackTheKnife]

I'm looking for battery for MP4 player (looks like iPod nano). Dead battery inside is 3.7V 200mAh with size: 36x20x4 mm and I have no idea which one I'm looking for. It can be more mAh then that default one. Thanks.

Do you have a picture, or a serial/model number, that we could refer to?

There is a bunch of numbers (IMO serial) 042035SP and FF12 what I have no idea what is mean

I found this http://www.usb-thai.com/forum/index.php?language=english;topic=52 but still I have no idea what kind of battery it is.

Hi, I am looking for the same battery - did you manage to find one? My battery does not hold a charge - the MP3/4 works while plugged into the PC but when you unplug it, it doesn't work. This is the number on the battery 042035SP 3.7v 200mAH FC28
