Three times?  What are you driving these days?

Much of what's out there,  and what's been out there since about the
mid-1980s has tended toward requiring somewhat higher CCA in a somewhat
lower-profile package.

My car,  for example,  had a group 26 battery in it when I got it.  At the
point it died,  I could probably have replaced it with another one of that
type,  but instead I chose to go with a group 34,  which is about the
biggest I was going to fit in there.  Even not wanting all that much,  I
was still looking at 675 (?) CCA,  and that's not the top-of-the-line model
either (got it at Sears).  That was somewhat more than halfway to the
amount mentioned above.    Even if I'd gone for a group 26,  the
options would still have been fairly limited,  and I'd probably still have
spent $40-50 or so.  And that's one of the cheaper batteries you can get.
