Well, the cradle that holds the stock battery isn't big enough for both the stock battery AND a box around it. Not to mention that you'd lose the ability to use the quite stout factory clamping methods.

I ended up being forced to replace my perfectly good stock battery with a non wet-cell battery in the stock size (group 48). The box is only required for wet cells. It's about 5 lbs heavier but it's the only solution I could come up with. I'm fortunate that these things are available in my stock group number, that doesn't appear to be the case for very many cars.
