Rolls for wet not for re-branded batteries.
Concorde said "no" to their offer to re-brand the Lifeline. Exclusivity defines with ultimate contrast the difference between their batteries and lesser absorbed glass mat units. Imagine that, a thickest plate truly deep cycle battery offering the highest recommended recharging rate per ampere hour capacity. My 31 standard eats 107 amperes and does not even warm to the occasion.
The "recommended" rate will make the R&S battery live say 5% longer. Pencil out a cost scenario and see whether generator wear-out, run-time and fuel costs justify the five percent. Engineers are purists. Reaching for the theoretical superlative. Gaining an MEE plus an MBA created quite a conflict. It took me a while to sort things out at college. Put at odds, a Chemistry Professor would gleefully strangle an Economist. Throw in a professor of "electronology" and Kosovo, might have looked like a Mr. Rogers program.
It really isn't funny, each would gladly sacrifice the wishes and perspective of the others in near sacred homage to his own discipline.
And friends and family nearly screamed in frustration at my absolute refusal to acquiesce to merge with sanctimonious corporate fiefdom mentality.
A destiny of death or death row. Perhaps a continuance of my great-great Uncle Erwin's obstinate genetic refusal of parroting politic non compos mentis.
The realization of a common-sense conclusion does not require a PhD. Disassociate yourself from the issue and examine it from a clinical perspective.
Or from the second dimension - What is more important to you...efficiency...or theoretical perfection? They are not the same animal.
