My Pal Mickey wouldn't work on our latest trip Feb/07, he would only vibrate! The CM at AK said he needed new batteries. She proceeded to tell me they only had Lithium Batteries at their store. She put them in, and Mickey worked fine. The next day, NOTHING! We were at Epcot, and we went into the first store on the right (right at the ball). I told him my predicament and he said,"Tell me you didn't put Lithium batteries in him?" I told him I didn't but a CM did at AK. He put in new batteries and he worked for about 5 more minutes. The next day we went to MK, and again Pal Mickey wouldn't work! We went to the store on Main St. right beside Uptown Jewellers where they sell Pal Mickey. The CM took Mickey apart, put new batteries in him again, reprogrammed his nose, and nothing. I again explained my dilemma over the past few days starting with the CM changing the batteries at AK. She said that you can NEVER put Lithium Batteries in Pal Mickey, because they're too strong and they short circuit him! She took him in the back for a few minutes, and came back saying that since it was due to an error of a CM, they were giving me a new Pal Mickey! We had the original one from the first year, so now we have Sorcerer Mickey. His outfit comes off to look just like regular Pal Mickey. So let it be a lesson to you! I went back to AK and told the CM who changed the batteries and told her about Lithium Batteries and Pal Mickey. She apologized profusely and was thankful that I came back to her to tell her.
