Below is a link to a page that list these. It is not the place I'll be buying. I can get these for about $115.00 each. Looking to replace the interstate 27's I have. they are at least 5 years old.
Would there be a reason to not use one as a cranking battery? All my electronics and livewells are hooked up the the cranking battery so I do not want to run it down. The current Interstate 27 is a Deep Cycle used as a cranking battery with no issues. Based on the specs it sounds like a great deal. Menard's can special order them so they should be new and if I time it right I might get an additional 11% off. Also these will be going into a 98 BassCat Sabre with a Merc 150EFI. The 27's are a pretty tight fit. Is there a big difference in footprint? I want to stay with a flooded battery.

So anyone ever used them??

Here are the specs:

Cold Cranking Amps (CCA) @ 0°F 725
Marine Cranking Amps (MCA) @ 32°F 900
Reserve Capacity Minutes @ 25A 205
Amp Hours (20 Hr Rate) 115

The weight is as at least 70 pounds
