Thanks everyone for the help. I jumped the car and took it over to an
AutoZone. They ran a test and the battery did come up bad this go
around. Previously, I had the battery tested at a Walmart and an
O'Reilly and both times the battery came up fine. But after testing it
myslef today based on advice from here it did seem that the voltage was
low. At any rate, after I put in the new battery it started right up.
However, I've replaced the battery before in this car <never with a new
one> and evnetually it would fail me. So, this battery is brand new
and I will keep an eye on the problem and let you all know if I have
continued problems.

Thanks again for everyone's help. Time now to head back up to college.

Jumping in here... if you're reading 15+ volts across the battery with
the car running, it's very possible that your voltage regulator is bad
and the overvoltage is killing your batteries over time - alternator
output should normally not be much over 14.5V with engine running and no
load (no lights, wipers, blower, etc.).

The regulator is, I believe, internal to the alternator, so you're
looking at needing to remove and rebuild or replace the alternator.
Have Autozone do a proper alternator test to make sure there's no other
problems, before you end up needing to replace your new battery again.
