I have a pair of PE-80s. I'm not sure what the number designators stand for, I think it's polar pattern. Mine are cardiod. They do use a single AA battery, no phantom power capability. I read somewhere that Phil Collins used to like them. They're not horrible but unless you're getting them for a real good price or you just want another color in a small diaphram condensor, I think there are better bangs for your buck out there.
