The old-school mastercraft unit will charge it, leave it on long enough to get a few volts in it and then swap over to one of the smart chargers. That, or if you have a running car, hook up the booster cables and let the running car run for ~15 minutes or so. That'll be enough to put a surface charge on the dead battery so the 'smart' charger will kick on when you connect it.
After at least 24 hours on the mastercraft charger with another battery in parallel, it might be starting to take a charge.
Now, should I change to my Ctek and recondition? Or just regular charge?
Reconditioning, in most cases, uses pulses to try and break-down build up (sulfation) on the plates...It can't hurt. I think most high-end smart chargers (CTEK included) will automatically go into reconditioning whether you set it or not if it detects that the battery needs it.
To answer your question, yeah, I'd probably switch it over to the CTEK at this point.
No guarantees with a battery at this point, it might come back to be serviceable again, it might not. Deep discharges like this are really not good for a starting (non-deep cycle) battery.
