Click,Clickety, goes the Starter???

I am getting between 15 and 17 when it is running. When I had
the car in California, I had it in a heated under ground garage and
sometimes I would not drive it for weeks. It would fire right up,
after all that time of sitting. I am going to try another battery,
when I get to the station tomorrow. I am going to be ticked off
if that battery is bad. I paid a little more money for it to have
the old school yellow cap battery. Its only about a year old.
I guess all my California cars, don't like the weather way up
here in Minnesota. I changed 2 batteries already on my Pick-ups.!!
