The barbie mp3 player only works when plugged into the mains does it have battery and if so how can I get it to work

tried to replace the charger and cleaned the usb port of the mp3, then check weather the battery is worn out which in need for replacement.

The player has a built in rechargeable battery that can charge by pluging it into a usb port on your computer or into a usb wall charger. if you have a mac i should warn you it will only let you charge nothing else.

You cannot fix it, but if you must do anything see if yo could use a different usb on it. If it doesnt work then you need to change or return it to where you bought it.

The battery will charge when running from mains. If you leave it plugged in for 20 minutes and then unplug, use and note how long before it shuts off, recharge again for 40 minutes and repeat.It shuould last a lot longer after a 40 min charge. And if it only lasts a minute or so after the first charge then the battery needs replacing (sometimes it's cheaper to replace the player) if it doesn't work at alll after 20min charge then definatly battery gone.

You have to change the battery. To do that you have to take that thing off on the back of the MP3 player and unscrew it to change the battery.

This works with Barbie MP3 player model BAR901:
If the songs are iTunes Store format (copy protected AAC) you can burn them to a CD (preferably a CD-RW, which you can reuse over and over) which in effect converts then songs to AIFF format with no copy protection, then import them as MP3s back into iTunes (Advanced > Create MP3 Version). (Note: Be sure iTunes > Preferences > General > Import Settings... > MP3 encoder is selected, or you will get Create AAC Version in the menu). Make sure View > View Options... > Kind is selected so you can sort the songs by the kind info column (that is, MP3 not AAC). Then drag your new MP3s out of the window into the main level folder of the Barbie MP3 player. Erase the MP3s from iTunes if you don't need them, since you already have AAC versions. Phew, not easy.
If you have a physical CD rather than iTunes store purchase, it's way easier; just import the tunes as MP3 (Advanced > Create MP3 Version, see above) and drag them into the Barbie player's root folder. The songs play then on the MP3 player. ;-)
