 ===== TL;DR =====
-  * Days of autonomy (or reserve) is the number of days of power one stores for days when zero charging is available.  It is planning for the Worst Case Scenario.
+  * Days of autonomy (or reserve) is the number of days of power one stores for days when charging is unavailable.  It is planning for the Worst Case Scenario.
   * A system whose [[electrical:12v:battery_capacity|capacity]] == [[electrical:12v:dailypowerrequirements|daily power requirements]] has one day of autonomy;  24 hours after a full charge there will be no usable capacity left.
-  * Depending on [[electrical:12v:power_mix|charging sources]] we might think in whole or fractional days
+  * Depending on [[electrical:12v:power_mix|charging sources]] it might be more useful to think fractional days rather than whole ones
 [[opinion:frater_secessus:pareto|about these summaries]]
   * the decision on how much capacity to purchase is economic as well as technical.

   * [[electrical:shore_power|shore power]] charging with [[electrical:converter|a converter]] or other charger
+  * charging  by [[electrical:12v:mandatory_solar|alternator alone]] but not driving some days
   * no field charging at all (charging at home only, no charging over weekend outings)
