Thanks, Cor! Egads, I'm typing faster than I'm thinking. Your
corrections are all right on the money. :-)

Most car batteries are flooded (i.e. not sealed). If you continuously
charge them, once they reach "full" they simply convert the excess
charging current into heat and gass

People mix up "float" and "trickle" chargers all the time. But they are
quite different devices.
A "trickle" charger delivers a more-or-less constant CURRENT, regardless

I can second Cor's advice. 13.5v is a good float voltage; better than
the usual 13.8v you'll find in most

New question.
What happens when you might forever overcharge a CAR battery with 30 mA
(during daylight).
I added an unregulated solar panel that typically produces only 30 mA to a
very remote cabin car battery deep in the woods. The c
Float voltage is likely higher than 13.5V but you should see what the
manufacturer says. Keep it below the float voltage rec, at 30mA (the
current for two bright LEDs and 0.4W) you are likely not harming.
It is correct that when charged excess generates heat and gassing. If you
are ever concerned

I added an unregulated solar panel that typically produces only 30 mA to a
very remote cabin car battery deep in the woods. The charge rate will give
a 2 hour per week use of the lights.
