Go to Harbor Freight and grab a screwdriver.
And compare it to a Wiha screwdriver.
US battery imports an un named unlabelled life cycle chart for a single cell battery and permits the reader to imagine its significance. This is unethical as hell and its de jour from US Battery.
The signifigance of survivability shows up at 20% capacity remaining cycles and there is no meaning zero information regarding percentage of original amp hours remaining at end of cycle life. Pure hocus pocus.
Hauling a half ton extra around to ensure >-20% max depth of discharge is not exactly intelligent. I know a client near San Lucas who successfully uses perhaps five or so TONS of VRB liquid calcium batteries. The last I checked they were going on their ninth year. Successfully.
Only catch is the bank dicharge limit is 85% remaining. The batteries were free. Mother earth can support a lot of weight. Ching Chong tires cannot.
Back to that farce of life cycle representation. Even a Lifeline would be hard pressed to compete with that <20% remaining life cycles. Now do you -really- think that chart is for anything else than a single cell accumulator?
US Battery refused to deal with me. So another OEM purchased their batteries for me to test. The only local company I gained respect for was Trojan and Ramcar. But there's a caveat - batteries from the Philippines for Ramcar. The Mexican LTH was another but at that time LTH did not manufacture a ciclando profundo battery. LTH is still skittish about acid starvation. No "heavy" batteries their GCs are around 210 AH.
Yeah. Me and my fetish against deceptive mumbo-jumbo again.
