Charger enters this stage if it detects battery sulfation or severe discharge.Once battery is rejuvenated, charger moves to Bulk stage.Stage 2: Bulk charge using charger highest rated voltage and current for the type of battery in use until it reaches 80% capacity.Stage 3: Absorption, the output voltage is limited to 14.7V while current declines as the battery charges to its full capacity without overheating.Stage 4: Float. At this stage, the battery is fully charged and the charger maintains the battery through pulse charging.Marine Kit:http://www.amazon.com/gp/product/B00HOUCLWE
