Interstate is good. However, if this is the second battery in a year, I'd suspect excessive current draw on the starter (typical as they get old and die) that is killing the battery, or either a current drain or a bad charging system unable to keep the battery up.
Do the test described, and find a battery/alternator shop that can do the correct starter and alternator testing. If you have a diode out in the alternator, it may not be able to keep up with the wintertime load, allowing the battery to stay half charged all the time. A starter with bad winding (the resistance goes up, they draw an astonishing amount of current, and do not turn fast enough) will croak one too.
