-====== insufficient Absorption ======
+====== dealing with insufficient Absorption ======
 In off-grid solar charging scenarios batteries are most often damaged by [[electrical:batterycide|chronic undercharging]].  Specifically, not holding the [[electrical:solar:charge_controller_setpoints|manufacturer's recomended Absorption voltage]] (Vabs), and not holding that voltage long enough((duration)) for acceptance to drop to endAmps.

-The Eternal Absorption approach completely forgoes Float stage, forcing the controller to stay in Absorption by setting Vfloat to Vabs. This addresses the controller issues above.
+The Eternal Absorption approach completely forgoes Float stage, forcing the controller to stay in Absorption by setting Vfloat to Vabs. This addresses the controller issues above.  It will not address the insolation problem on a given day, but extended Absorption will help reduce damage from previous days of poor harvest.
