Just wondering what the majority of misb collectors are doing about figures such as MP Grimlock that contain batteries. I really do not plan on selling him but the way things are going now, who knows. If I was to sell him, is there much difference between MIB and MISB? I have already had disastrous results with many of my original G1s and batteries. My Galvatron was eaten within, Sky Lynx didn't work, and I had to replace the cannon for Trypticon. Is MP Grimlock an easy open? Does opening him damage the box? Should have added, I have the Hasbro version.
