THat is asking too much of any battery. Except the Odyssey and Optima Yellowtop. But are you willing to pay $300+ for that? Even the Optima in 51R still has problems after being revised.

For the money, I'd just get a AC Delco or Supercharge Gold. Both are about $120. Just don't deep cycle them.

You have to use the regular size ones. The location in your EK can't support a larger battery, unless you do a battery relocation into the boot.
