Just thought I'd share this story for PS-2 users out there in case a freak occurence like this ever happens to one of you guys. So I was getting my gear set for a low-profile show recently, and everything was set up and the last part was inserting a 9V battery into the PS-2. Easy, right? Well, I put it in and then look down and see the low battery red light is on, which is odd, so I try to take it out to see what's up... and it won't come out! I can pull the battery out some bit, and I feel the spring stretching, but the battery won't come loose. It's close to show time so I decide I better do something and I pull really hard and then the battery finally comes free... but it lost one of the connectors!
I look in the PS-2 and see the battery connector (the bigger one of the the two) is stuck to the top of one of the two PS-2 contacts that are attached to the springs. Wow. I try to pry it off with a screwdriver key I have but no go, so I try to pull it off with a key and it comes off easily (I guess the jagged edge of the key was able to insert itself between the PS-2 contact and the battery contact that was attached to it. Luckily, it still works but now the spring is looser and I wonder if this thing is still going to be reliable in the future. I guess we'll see.
