I didn't see these numbers (29 volts & 1/3 Ah) anywhere in this book. WHere
did I miss them?

Yuasa publish a "Little red battery book" which recommends supplying a
sulphated battery with 29V current limited to 1/3 of the Ah capacity,
assuming the sulphation starts to break down the terminal voltage will
pull down to the deep discharge value ( about 10.8V for a 12V battery) A
comparator should be arranged to detect this event and switch the charger
over to constant voltage charging (about 13.8 to 14.4V).
