The NAPA batteries I mentioned are Group 31 S, with 925 CCA. And oh yeah, they cranked her right briskly.
Currently I'm using "dual purpose" batteries --sort'a deep-cycle-but-can-crank-some -- and they crank her... pathetically slowly. In fact, I may go to the NAPA store today.
The "Black Death" pandemic of the 14th century killed roughly half the population of Europe and Asia.
Please stay home until this pandemic is more safely behind us. And wear a mask, properly, when you must go out for groceries. The life you save may be mine. Thank you!
