TC Electronic Corona Chorus SCF limited edition not working with battery?

just picked up the pedal used as it was in great condition. Two gigs later I notice it wouldn't power on with a new battery in. It's very intermittent. But it does power up with power cord attached. Anyone experience this proble and have suggestion? Thanks.

 

Yes. Great question. This is happening with a brand new battery. I can get it reset by pulling out the 1/4" from the mono input but as soon as I turn it off it will not come back on.
