      • As soon as the max Soft Start timer (starts immediately when entering "Soft Start") of 6 hours is reached or when the battery reaches 10 V for 30 seconds the charger switches to the "Bulk stage"
    • Bulk Stage
      • Bulk Stage charges the battery with 14.3 V (100% of rated current) until the battery reaches 13.25 V
      • As soon as the battery reaches 13.25 V the Bulk timer will start counting after which it can charge the battery up to 12 hours until the voltage reaches 14.25 V
      • As soon as the max Bulk timer (starts when voltage level is above 13.25V while in "Bulk") of 12 hours is reached or when the battery reaches 14.25 V for 30 seconds the charger switches to the Absorption stage
    • Absorption Stage
      • Absorption Stage charges the battery with 14.25 V

    • Float Stage
      • Float Stage keeps the charger on a specific voltage level of 13.25V (100% of rated current) for a period and then will switch to the Maintenance stage
    • Maintenance Stage
      • As soon as the re-cycle timer reaches 14 days (336 hours) or when the voltage drops below 12.8 V for 30 seconds the charger switches back to Bulk stage
