Move it - I really dislike seeing a drooling battery, and they all do, in an otherwise clean engine compartment. Something else - why not go to one of the "dry" cell batteries, get away from that monster and almost hide it from sight. I took my big Optima out and replaced it with an Odyssey - reduced the weight and footprint by 2/3rds and only lost a minimum amount of CCA (720 vs 680 for the new Odyssey).
A couple of photos to show the difference:
The tape indicates how big an area the Optima covered. I was not done wiring in this photo.
Almost done here(it is now)
