John,
Do you use a battery maintainer?? They can help (but AGMs should have
one tuned for them).? Have you had your starter rebuilt?? The field
coils, in particular, can degrade and reduce the starter output
considerably.? Solenoids degrade over time, too.
It doesn't get that cold where you, and I used to, live; you shouldn't
have that much trouble starting your Healey in the winter, even if it's
sat for a couple months.? Mine would take 10-15 seconds of cranking in
the winter after sitting to start, as opposed to maybe 5 seconds in
warmer months.
Switching to a lower-viscosity oil, for the winter at least, might help
some too.? I use 20W-50 year-round.? My experience with the
'boosters'--exactly one--is that they might help a marginal
starter/battery over the top, but will not cold start a completely dead
battery, and least not on a big 6- or 8-cyl engine.
