The charger will begin in Standby mode, indicated by an orange LED. In Standby, the charger is not providing any power. 4.) Press the mode button to toggle to the appropriate charge mode (press and hold for three seconds to enter an advanced charge mode) for the voltage and chemistry of your battery. 5.) The mode LED will illuminate the selected charge mode and the Charge LEDs will illuminate (depending on the health of the battery) indicating the charging process has started. 6.) The charger can now be left connected to the battery at all times to provide maintenance charging.Understanding Charge LEDs. The charger has four (4) Charge LEDs per bank - 25%, 50%, 75% and 100%. These Charge LEDs indicate the connected battery(s) state-of-charge (SOC). See the explanation below: LED Explanation Maintenance Green LED 25% Red LED The 25% Charge LED will slowly pulse “on” and “off”, when the battery is less than 25% fully charged. When the battery is 25% charged, the red Charge LED will be solid. 50% Red LED During maintenance charging, the 100% Charge LED will pulse “on” and “off” slowly. When the battery is topped off and fully charged again, the 100% Charge LED will turn solid green. The charger can be left connected to the battery indenitely. 75% Orange LED The 50% Charge LED will slowly pulse “on” and “off”, when the battery is less than 50% fully charged. When the battery is 50% charged, the red Charge LED will be solid. The 75% Charge LED will slowly pulse “on” and “off”, when the battery is less than 75% fully charged. When the battery is 75% charged, the orange Charge LED will be solid. The 100% Charge LED will slowly pulse “on” and “off”, when the battery is less than 100% fully charged. When the battery is fully charged, the green LED will be solid, and the 25%, 50% and 75% Charge LEDs will turn “off”. 100% Green LED 25% 50% 75% 100% 25% 50% 75% 100% 25% 50% 75% 100% 25% 50% 75% 100% 25% 50% 75% 100%6 Understanding Advanced Diagnostics. Advanced Diagnostics is used when displaying Error Conditions. It will display a series of blink sequences that help you identify the cause of the error and potential solutions. All Error Conditions are displayed with the Error LED and Standby LED ashing back and forth. The number of ashes between each pulse denotes a potential Error Condition (except reverse polarity and low-voltage battery). Error Reason/Solution Single Flash Battery will not hold a charge. Have battery checked by a professional. Possible battery short. Have battery checked by a professional. Battery voltage is too high for the selected charge mode. Check the battery and charge mode. Error LED Solid Red Reverse polarity. Reverse the battery connections. Battery voltage is too low for charge to detect or charger is in supply. Jumpstart the battery to raise the battery voltage.

Step 1 & 2: Analyze & Diagnose Checks the battery’s initial condition, including voltage, state-of-charge and health, to determine if the battery is stable before charging. Step 3: Recovery Initializes the Recovery desulfation process (if needed) for deeply discharged or sulfated batteries by pulsing small amounts of current. Step 4: Initialize Starts the charging process with a gentle (soft) charge. Step 5: Bulk Begins the Bulk charging process based on the condition of the battery and returns 80% of the battery’s capacity. Step 6: Absorption Brings the charge level to 90% by delivering small amounts of current to provide a safe, efcient charge. This limits battery gassing and is essential to prolonging battery life. Step 7: Optimization Finalizes the charging process and brings the battery to maximum capacity. In this step, the charger utilizes multi-layered charging proles to fully recapture capacity and optimize the specic gravity of the battery for increased run time and performance. The charger will switch to Maintenance if the battery tells the charger that more current is needed.10 Step 8: Maintenance Continuously monitors the battery to determine when a maintenance charge should be initiated. If the battery voltage falls below its target threshold, the charger will restart the Maintenance cycle until voltage reaches its optimal state and then discontinues the charge cycle. The cycle between Optimization and Maintenance is repeated indenitely to keep the battery at full charge. The battery charger can be safely left connected indenitely without the risk of overcharging. Charging Times. The estimated time to charge a battery is shown below. The size of the battery (Ah) and its depth of discharge (DOD) greatly affect its charging time. The charge time is based on an average depth of discharge to a fully charged battery and is for reference purposes only. Actual data may differ due to battery conditions. The time to charge a normally discharged battery is based on a 50% DOD. Battery Size Approx. Time to Charge In Hours
