CHARGING STAGES
Bulk Charge (Level 1) – Maximum current charging until batteries rise to Absorption level
Absorption Charge (Level 2) – Constant voltage charging and battery is over 85%.
Equalization Charge* (Level 3) – Only for WET battery or Calcium battery type, when the
battery is deeply drained below 10V, it will automatically run this stage to bring the internal cells
as an equal states and fully complement the loss of capacity.(Gel and AGM battery do not run
