-  * 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.     * 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.
