STEP 1: DIAGNOSIS (Check if battery has connected with the charger and also check battery voltage) STEP 2: DESULPHATION (If battery voltage is too low, programs automatically generate pulsing current to remove sulphate, up to 5 hours) STEP 3: ANALYSE (Check if the battery voltage reaches to the threshold after desulphation, and charging begins if the battery voltage is OK) STEP 4: SOFT START (Charge with echelon constant current) STEP 5: BULK (Charge with constant maximum current until battery voltage is reached to the threshold) STEP 6: ABSORPTION (Provide gradually declining current charge for maximum battery voltage) STEP 7: ANALYSE (Test if the battery can hold charge) STEP 8: MAINTENANCE (Continuously monitor the battery and charging current will intelligently adapt to the variable battery voltage).
