I had a couple of gremlins at my house over the Thanksgiving holiday (2 1/2 and 4 years old). Besides the devistation to my holiday village that was left behind, they also figured out how to turn on the light bricks and leave them on. Needless to say, there isn't much left of the battery in the brick.
So, the question is how easy or hard is it to replace the battery? And, where can I purchase a battery replacement?
