There has been alot of discussion about this on the Cardinal owners
site lately. It appears that the RG batteries are good only if you fly
alot, flight schools are good places for them. If flown infrequently
(less than once a week)then old style wet cells last longer.

Dunno. Had an RG in the Fly Baby, but only fly it 35 hours a year or so.
Replaced it after three years when I began having starting problems, but turns
out it wasn't the battery's fault (bad starter clutch).

Put in one of the Odyssey dry cells. Less weight, smaller, cost about the same.
Working fine, turns the engine nicely, but it's only been a year and a half.
