Battery box noise when touched??

Wondering if anyone else has had this problem? I bought an EBMM Albert Lee SSS, all seems fine with the guitar so far without opening her up, but I have noticed that when I touch the battery box I get quite a lot of distorted noise, could this be loose wires, bad battery connection?

So far I can’t even figure out how to remove the battery and I don’t want to force it and break something.

Any input would be appreciated.
