I've got FFMetal's battery box installed in my trunk. I'm extremely happy with that product, but I have a question about your particular experience.

I currently have an Optima Red Top 34 installed in that box. In fact, Bill Dane specified that the battery box is designed for that particular product and told me that alternatives may or may not fit. It's the "may or may not" part I'm hoping you might have some experience with. It's time to replace the old red top and I'm looking to see what options I have.

So, if you have his battery box, have you installed anything other than an Optima? How'd it fit?

Worst case, I install another Optima. Best case, I can choose between maybe two or three options. Thanks in advance!
