Ask Telstra and Navy how they keep their lead acid batteries long term. I remember the 1100AH 2.2V cells all joined together in the battery rooms, 2x 50V battery banks, feeding a 1600A busbar [abt 6"x1/2" copper bar(s) AFAIR] @ Bathurst St exchange-Hobart. Legend has it that a spanner could be melted by shorting it across the battery. I don't have proof anyone did so, but the comment was common that doing so at the end of the bus would NOT blow the 2000A fuse near the batteries. A new genset was installed whilst I was there. I remember watching the staff commission & debug the new buck/boost charging system. Crude, but it eventually worked.
