Battery Cover Purpose?

The battery cover is used to help reduce the temperature of the battery. Heat kills the separator plates inside the battery so the cover helps to keep it cooler; especially with the air intake that forces air into the case when the vehicle is moving. It is not used for waterproofing.

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.
