What are you using for a trunk mounted battery?

On my Dart resto, the battery is relocated in the trunk. I have the good thick gauge cable and will be buying a new hold down kit for a neater look. I am looking at Optima batteries. It looks like the yellow series is the better one.
It's a 440 with 11.5 compression, electric fan and electronic ignition. Other than that there are no electric power accessories. I had a big Interstate battery in it before but have since put it in my b-body wagon. I didn't want it to sit around for years not being used. Thank all.
