Turned off sound when I thought was gonna die, seemed to be pattern in them coming (this was right after north door), but then the north one wasn't close when I thought it was, was still okay and was able to get battery in terminal, but got killed not too long after, but I don't see how to really strategize here, especially with losing the third battery, and the movement happening usually at a different spot from where I'm looking, usually letting one get too close.
