I'm interested in expert opinions on this battery I just found. It's supposed to be a replacement for the Sonnenschein A512/40. It fits and can use post terminals or bolt terminals. The guy at the battery store said it might not do well as a cranking battery since its intended use is as a deep cycle for UPS. What do y'all think?
