Ive an odyessy PC1200, small, sealed, and excellent quality but a little on the heavy side 38lbs. I worked at Enersys in Mo., where we made diehard,odessy, stingers, Tank batteries, Aircraft batteries telecommunication batteries etc. Let me tell ya, when yours decides to go you most likely wont get much of any warning. your at 7 years now on yours (car's actual build date?) thats about the expected lifespan of high quality battery.

Id go with interstate ASAP

BTW, my 04 still works and holds a charge too, just didnt want to get stranded somewhere
