Hi, bought my daughter one of those keyboards from ELC for Xmas.
Batteries ran out so opened it up to find they had leaked all over the battery compartment. They were 4 'C' Kodak branded batteries. Cleaned it up and changed it to 4 Tesco batteries. Opened it up to check 2 days later and the batteries had started leaking again!
Whats the problem, cheap batteries or is the toy causing them to do this?
