Fitted the Yuasa UR1 battery yesterday 30 Ah , CCA 300 A. Its virtually the same size as the original Banner but the terminal lugs are orientated differently. Morgan leave no slack in the cables so it was difficult to get them bolted up. Started first go, reckon my starting difficulty was the old battery was just not turning the engine over fast enough. The Exide AGM 21-31 is 31Ah & CCA 330 it costs almost twice as much the Yuasa.
