Since I don't have the prop with me (I'm at work right now) and I'll be going to an electronics store within a few hours to get a replacement battery for my neuralyzer: can someone who also has this prop let me know what battery type it uses? (I didn't plan to go to the store today, so I didn't look at the battery at home, but since a meeting is canceled I can go over to the store, but don't know what battery type to look for). Thanks to the person who can tell me within the next 3 hours .
