Ok then amps going up on a near dead battery is normal. As the battery comes back from near dead, it can accept more and more amps with the charger voltage as set.
Eventually the battery gets back to "normal" and accepts max charger amps for a while, and then amps taper as usual until the battery is full.
If that is what you have going, then IMO (subject to what Mex might say) set the charger to 14.4ish and let the amps climb as long as the battery does not get hot. Amps should only climb to the charger's max amps anyway with a "current limited" charger.
I don't know how that charger works for max amps, so Mex might have to say how that is.
Expect this to take a very long time if the battery will indeed recover.
