-In a perfect world, lead-acid batteries (both flooded and AGM) would be discharged no further than 50% then [[electrical:12v:charging|fully charged]] again each day.
+In a perfect world, lead-acid batteries (both flooded and AGM) would be discharged no further than 20% then [[electrical:12v:charging|fully charged]] again((ie, to 100% State of Charge)) each day.  In some studies this 20% depletion yields the most Ah/$.  The downside is carrying around a lot of "dead lead", capacity that is never used.
+In actual usage it is more common to discharge to 50% SoC.  This allows 2.5x the power to be used overnight at the cost of longevity.
 It is easier to get the batteries fullly charged each day when [[electrical:solar:overpaneling#vs_battery_bank|they are overpaneled]], but that trades battery health for less reserve for [[electrical:solar:output#insolation|days of poor insolation]].
