OK, maybe all the bike batteries are "sealed" now but that doesn't mean that they are AGM.
All AGM batteries are sealed but the reverse is NOT true.
And a "standard" 12V. wet cell battery (lead acid) is 12.6V nominal; 2.1V X 6 cells.
If you start adding in things like calcium, I think the float voltage is even a bit less.......but those exotic formulations probably aren't common in bike batteries. :cool:
