the positive post hits the hood and pushes it up a bit....someone on here cut that post about a 1/4 inch and it worked but then someone else tried it, went to far and cut into the core or something like that....so basically no.

This is from a past post of mine on the CTS forum:

"I just got off the telephone with Optima's Tech Support and I was told that you are NOT to cut down the top posts of their batteries as the top post is the primary and the side posts are the secondary. By cutting down the top--which are hollow inside--you reduce the current to the side terminals. Don't believe me, then call Optima Toll Free: 888-8OPTIMA (888-867-8462)

I asked them whether they would be making a battery for our CTS and they have kicked the idea around, but there are no plans at the present."
