Optima Batteries

[Booyah]

Does anyone have one of these?? Also, what would constitute a moderate load or a heavy load on the battery. I know a huge stereo system would be a heavy load but what would a normal setup be considered?

I have one... don't really know what constitutes a 'heavy load'.
I know the high-speed fan really does! I have it manually wired and it sure draws when I engage it...
