Nor deep discharges. It all fits when you think about it. Deep discharges, fast recharges, starting pulses, and a 140 amp alternator zaps the battery. Think it through. If it didn't doesn't add up there would be well publicized issues arising.
Continuous deep cycling is the triathlon test of any battery. Over and over and over cycling to 50%. Very high total kWh usage.
A wide range of float voltages is positively necessary to fit the construction of flooded batteries. There are 1%, 2.0%, 2.75%, and 5% antimony alloys. Antimony calcium (hybrid), and a plethora of electrolyte densities. No way on earth is a single float voltage value valid for this range.
But AGM is 99% minimum pure lead, with minor amounts of calcium, and silver. Electrolyte is almost universally 1.300 density. If they should space plates and mats far enough apart to affect chemistry it would have a severely negative impact on impedance, therefore performance. Coil plate batteries are not part of the universe so I ignore them. My car does not leap 15-foot arroyos and I do not wear a three point safety harness.
