The nameplate 'rating' may or may not meet your
design goals for battery-only endurance . . . and
the criteria for periodic testing that ultimately
takes a battery out of service.
What ever battery you purchase is going to start
your engine just fine . . . what it's capable
of doing a year from now in terms of battery only
ops is something you won't know until you test
throughout the course of its service life.
We've studied and shared experiences with
batteries here on the List since day-one.
Batteries have played prominent roles in many
of the dark-n-stormy-night sagas printed
in the aviation rags.
I assert that for every battery
player in those bad-day-in-the-cockpit stories,
NONE of them received any quantified
performance monitoring. Further, authors
of those stories seldom displayed any understanding
of their airplane's electrical physics and function.
Bottom line is try any battery that looks good
to you for any feature . . . but keep an
electronic 'stethoscope' on its innards.

rest is stamp collecting" -Lord Kelvin-

Un impeachable logic: George Carlin asked, "If black boxes
survive crashes, why don't they make the whole airplane
out of that stuff?"
