The no-load voltage is probably greater than the loaded voltage. I believe the 14.3 to 16.5V spec is under full load.
I would set the Power Supply to 14.7V (no-load) and then connect to battery. If the battery is discharged then PS voltage will drop down the battery voltage plus surface charge. The PS will charge at 13A. Battery voltage will slowly increase to 14.7V. When it reaches 14.7V the current will taper. Now you need to be careful. How long can you sustain this voltage on the battery?

--Using a reliable multimeter on the 15V studs, I get an adjustable voltage range of 12.6v to 17.5v. It is the same under no load and a light load (LED lamp). The specs state a voltage range of 14.3 to 16.5. Did I just get an early Christmas gift with this wider voltage range?
