It's really a bad plan to have a battery that's not securely mounted. Even if you're just mall-crawling with it, a battery coming loose during an accident could very well turn a simple problem into something deadly if it shorts out and catches fire.
There's lots of ways to cobble up a mount, please look into getting it secured!
That said, I've used optimas for ages on our boat, they're great. I most recently had the battery in the WK replaced with a Diehard AGM. I think it was all of $10 more to upgrade to it from a regular lead cell model.
