Discussion: One thing I think is often missed is that one should
always consider their battery as a "reservoir" of energy, only
capable of offering what it has on board. If the alternator goes
Tango Uniform shortly after departure, reservoir is depleted
somewhat from bringing the mighty Lycoming to life. And if extended
cranking prior to departure were the case, (cold temps, hot starts,
blown procedure, whatever...) reservoir just might be quite a bit
lower than typical. Methinks it wise to consider remaining battery
available based on general condition, plus most recent consumption &
time recharging in the event of a failure...

For the redundant types, why not just put on a second alternator, it
is a lot lighter and my primary alternator was a lot cheaper than
the battery ($70.00).
If the alternator fails upon take off, maybe, it might just be
possible to land where you took off from? Of if in route maybe you
could land at the nearest airport? When I fly cross country I use
airports as my waypoints. At least in the east, seldom do I have a
waypoint that is more than 30 miles away!
On the other hand many of my aerobatic friends fly with no alternator
at all and battery only, one guy gets 30 starts before he has to
recharge the battery. And yes they do fly cross country to get to
aerobatic meets.
Two seats for two pilots with two alternators and two batteries! Why not?

"Cause I'm a two-seat (typically one-pilot), one alternator, one battery kinda pilot: Limited budget. No IFR. No question more redundancy is better when mission dictates, but design for the mission. And always understand the physics of whatever configuration you aviate with...
Good discussion-
