I'm sure this isn't news to many here, but there is a lot of discussion
on batts and chargers in the Aeroelectric list archive. Plenty of data
points and model numbers. Try a search using "Odyssey & charger".

So here is my confusion. Say that you use the "correct" type of charger
to fully charge the battery, then you install the battery in the plane
and go fly a 5 hour cross country. Since you do not have a "special"
alternator, is it going to ruin the battery?
What is the fundamental difference in the way that the alternator
charges, versus the Battery Tender, versus the Battery Minder?

The different battery constructions .... flooded, AGM, gel, ..... have
different charge profiles for optimum life and capacity. There is so
much info out there on the care and feeding of batteries that you won't
find the time to read it all.
The dilemma in flying Vs. trickle charge is simple .... the flying is
only for a few hours at a time (typically) while the trickle chargers
are hooked up for days, weeks, or months. The cheaper chargers really
don't have any 'smarts' to control the charging curve and the charger
will force-feed the battery whether it needs it or not. The voltages at
rest, after being fully charged, vary amongst the different construction
technologies and so the 'one size fits all' charger doesn't work. My
charger has selectable battery types and is also a desulfator. I move
it around my various batteries to keep them happy. My last battery (not
an Odyssey) in the Traumahawk was 8 years old when I replaced it so I
think I may be doing something right. I haven't decided on the battery
for my -10 yet but I will probably lean toward a sealed gel type.

I'm no expert but I think you have the trickle vs flying thing right.
I understand the other problem with some trickle chargers (e.g. my old
'Battery Tender') is that they are unable to bring a discharged AGM
battery back to a fully charged state. I guess the charging level is
set such that it won't ruin a battery if hooked up forever. (sorry if I
repeated myself here)
Check out Aeroelectric for more details, numbers, graphs, etc. Bob
Nuckolls experience with the Schumacher line of chargers (Walmart) is
what led me there and it's working well with my collection of AGM and
lead acid batteries. It has a gel setting too.

As I have posted before.
A while ago, I spoke with the Odyssey engineer regarding the proper charge voltage
during operational usage. The Odyssey batteries like to see a minimum of
14.3 and ideally around 14.5 volts. Most aircraft regulators are set somewhere
between 13.8-14.2. I suspect that a lot of the premature failures are caused
by improper operational charge voltage, as well as the improper battery charger
for this type of battery. The Odyssey charger starts its charge cycle at
around 14.7+ volts, depending how dead the battery is. (see below graph) Some
brands of external regulators are adjustable and could be set higher. In the
case of the Plane Power internally regulated alternators, it's a little more
difficult. The only way to increase the output voltage of the Alternator is
to create a voltage drop, such as a diode, in the field line. In the PP case,
the field line is used as the voltage "sense" input.
My Plane Power 60A alternator sits at 14.6 volts during normal flight. Most all
modern avionics are capable of regulating down from 30+ volts. Older avionics
maximum operational voltage should be verified prior to increasing your bus
voltage.
