I avoid HC batteries. I have a bank of the 370 AH batteries, and
they seem ok, not great.

IMHO Interstate makes a decent battery. It sounds like to me that
you are not Equalizing but just trying to BULK. You'll need at least
one robust EQ cycle to bring the SG's in line and likely 2-3 a
couple of days apart. At least the Magnum's of a couple of years ago
are not intuitive to get into EQ, as I recall you need to 1st be in
BULK charging before it can be set to EQ and this is/was done by
holding down the "Charger" button until it moves into EQ. Wrenches
please correct my fading memory if this is not correct. I would get
the V to 62-63 and hold it there for 3-4 hours and then recheck your
SG and see if further EQ's are in order.
Good luck!
