   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?"
