I have found the Banner spec from the Banner 530-03-!2v 30AH as shown in my original 2012 parts book. They are: 300A coldcrank. 187mm L, 128mm W, 165m H. LH Front Negative bolt on post. The only battery I have found with a quick search in France that has a suitable cranking current is over €400. In any case I have found the French storage people have already bought a lead acid replacement for my M3W. I just hope it is not one of the useless Banner batteries. That will make battery #4 since 2012, 2 x Banner and 1 Yuasa. I had hoped the Yuasa might be better in the M3W, since on my Yamaha 700cc (single cylinder) Raptor R quad bike, I only replaced the Yuasa starter battery once in 15 years and the second one was still going strong when it was stolen.
