3DS Two new Limited Edition 3DSXL's coming to EU!

[Twisted]

I just started collecting 3DS systems as well..i have 1 Wal-Mart "exclusive" for US Mickey Mouse edition, 1 Yoshi edition, 1 Japan Luigi edition, and 2 Japan Persona Q editions..i am little nervous because I am a sealed collector and I was told since these contain lithium ion batteries, that eventually over time..these batteries will begin to corrode and LEAK.how many modern handheld collectors are worried about this as well?
