Cha-ching... we have a winner. Step right up and collect your prize, sir.
Heat is the numer one killer for batts' it takes it's toll on them... hense the somewhat short lifespan. When I bought my truck new in 97 it didn't have anything to protect the batt, and I had to replace it in a about 3 or 4 years. When we bought my wifes 4wd Tahoe new in 01, it had a foam koozie like material around the batt, and it was still in there when we sold it in July of this year, same batt.
