Hello from Atlanta, Ga.  Both  of our  '81s are hard to start on cold
mornings.  The Rated 580 cranking amp batteries in each van are from my
FLAPS and are less than 18 months old.  However, when I put either battery
on my charger, charge it full and then try to start the van, it cranks on
the first go--even in 20 degree mornings....
Questions---  Is it that I need more powerful batteries, ones with more
cranking amps?  What else might be the problem?  What are other listees
using for batteries, especially those folks in really cold places?  Thanks!

Regards,

Mike and Christina Nichols
