My 16XRB had a Interstate. I personally only buy Walmart Batteries, since I get the best use and the best warranty out of them. They honor a real replacement, and pro-rated as it says on the battery. Not like some other places.
Since the Interstate 2 days after I bought mine (used) was real hot, I opened up the battery box and smelled acid. The charge was boiling it, probably due to low water.
I considered the Walmart Deep Cycle Group 24, for $99, 2 year replacement, but thought I'd bite the bullet and go with the Optima Blue Top of the same.
I have only been on the road for 3 weeks, so I don't have any long term results, but it is working, stays cool, and it's one less thing that is a needle in my brain.
