I can´t explain it well in english, batterys or rechargable batterys like they are in MP3 players have liquid or paste inside, which can run out or so and destroy things or skin. (I really can't explain it well in english because I don´t know the specific words xD)
So some countrys may not allowed this stuff to be imporeted so HMV doesn´t ship it.

Yes, the liquid in most batteries is corrosive and can cause damage to the human body (even if you don't touch it, it can still be inhaled). This liquid may start leaking from the battery at any time, but particularly if it has been lying unused for a while. Some batteries may also even be flammable (I think some rechargeable batteries, like the ones used in MP3-players and possibly PLAYBUTTONS, may have this risk), not to mention that a battery can easily power a bomb. So with the current customs security concerning liquids and possible bomb materials, it's not easy to get them through.
