For lead-acid battery charging, Unitrode makes a chip that looks really
good:  the 3906 (2906, mil-spec).  I have a couple but have not built
the charger yet.  It monitors charge current and voltage, keeps the
charged battery going through a slight charge/discharge cycle, monitors
ambient temperature internally to adjust its charging parameters, etc.

The manufacturer's application notes are involved.  There was a cookbook
sort of article about it in QST for July (I think) 1987.
