How To Use
Charging Modes
The GENIUSPRO50 has seventeen (17) modes: Standby, 12V, 12V AGM, 12V LITHIUM, 6V, 6V AGM, 6V LITHIUM, 24V, 24V AGM, 24V LITHIUM, 6V REPAIR, 12V REPAIR, 24V REPAIR, 12V SUPPLY, 24V SUPPLY, 10A Mode and Force Mode. Some charge modes must be pressed and held for three (3) to five (5) seconds to enter the mode. These “Press and Hold” modes are advanced charging modes that require your full attention before selecting. It is important to understand the differences and purpose of each charge mode. Do not operate the charger until you confirm the appropriate charge mode for your battery. Below is a brief description:
Using Lithium Charge Modes.
Lithium charge modes are designed for 6-volt, 12-volt, and 24-volt lithium iron phosphate (LiFePO4).
CAUTION
USE THIS MODE WITH EXTREME CARE. THIS MODE SHOULD ONLY BE USED WITH 6-VOLT12-VOLTLT, AND 24-VOLT LITHIUM BATTERIES THAT HAVE A BUILT-IN BATTERY MANAGEMENT SYSTEM (BMS). LITHIUM-ION BATTERIES ARE MADE AND CONSTRUCTED IN DIFFERENT WAYS, AND SOME MAY OR MAY NOT CONTAIN A BATTERY MANAGEMENT SYSTEM (BMS). CONSULT THE LITHIUM BATTERY MANUFACTURER BEFORE CHARGING AND ASK FOR RECOMMENDED CHARGING RATES AND VOLTAGES. SOME LITHIUM-ION BATTERIES MAY BE UNSTABLE AND UNSUITABLE FOR CHARGING
Using Supply Modes. [Press and Hold 3 Seconds While Not Connected To Battery
Supply Mode converts the charger to a constant voltage DC power supply. It can be used to power 12VDC devices, tire inflators, seat heaters, and more. As a power supply, it can also be used to retain a vehicle’s on-board computer settings during battery repair or replacement. 13.6V Supply (12V Supply) provides 13.6-volts up to 50A. Charger output voltage will drop if the output load exceeds the 50A current limit. 27.2V Supply (24V Supply) provides 27.2-volts up to 25A. Charger output voltage will drop if the output load exceeds the 25A current limit. CAUTION.
USE THIS MODE WITH EXTREME CARE. SUPPLY MODE DISABLES SAFETY FEATURES AND LIVE POWER IS PRESENT AT THE CONNECTORS. DO NOT TOUCH CONNECTIONS TOGETHER. RISK OF SPARKS, FIRE, EXPLOSION, PROPERTY DAMAGE, INJURY, AND DEATH. Using Repair Modes. [From Standby Press and Hold 3 Seconds While Connected to the Battery] Repair is an advanced battery recovery mode for repairing and storing old, idle, damaged, stratified, or sulfated batteries.
Not all batteries can be recovered. Batteries tend to become damaged if kept at a low charge and/or never allowed to receive a full charge. The most common battery problems are battery sulfation and stratification. Both battery sulfation and stratification will artificially raise the open circuit voltage of the battery, causing the battery to appear fully charged, while providing low capacity. Use Repair in an attempt to reverse these problems. For optimal results, take the battery through a full charge cycle, bringing the battery to full charge, before using this mode. Repair Mode can take up to four (4) hours to complete the recovery process and will return to Standby when completed. Repeated repair cycles may be needed depending on the size and condition of the battery; however, battery temperature must be closely monitored.
CAUTION
USE THIS MODE WITH CARE. THIS MODE IS FOR 6-VOLT, 12-VOLT, AND 24-VOLT LEAD-ACID BATTERIES ONLY. THIS MODE USES A HIGH CHARGING VOLTAGE AND MAY CAUSE SOME WATER LOSS IN WET (FLOODED) CELL BATTERIES. BE ADVISED, SOME BATTERIES AND ELECTRONICS MAY BE SENSITIVE TO HIGH CHARGING VOLTAGES. TO MINIMIZE RISKS TO ELECTRONICS, DISCONNECT THE BATTERY BEFORE USING THIS MODE.
Force Mode. [Press & Hold for 5 seconds
Force mode allows the charger to manually begin charging when the connected battery’s voltage is too low to be detected. If battery voltage is too low for the charger to detect, press and hold the mode button for 5 seconds to activate Force Mode, NOCO Professional Battery Charger, then select the appropriate mode. All available modes will flash. Once a charge mode is selected, the Charge LEDs and the selected mode LED will alternate between each other, indicating Force Mode is active. After five (5) minutes, the charger will return to the normal charge operation, and low voltage detection will be reactivated.
Using “Reduced Charge Current Mode”. [Press the 10A Mode Button
Reduced Charge Current mode will NOCO Professional Battery Charger allow the unit to operate at a charge current of 10A. This mode is available at any time and can be used with the following modes only: 12V AGM, 12V LITHIUM, 6V, 6V AGM, 6V LITHIUM, 24V, 24V AGM, 24V LITHIUM, and Force mode.
Connecting to the Battery
Do not connect the AC power plug until all other connections are made. Identify the correct polarity of the battery terminals on the battery. Do not make any connections to the carburetor, fuel lines, or thin sheet metal parts. The instructions below are for a negative ground system (most common). If your vehicle is a positive ground system (very uncommon), follow the instructions below in reverse order.
- Connect the positive (red) eyelet terminal connector to the positive (POS, P,+) battery terminal.
- Connect the negative (black) eyelet NOCO Professional Battery Charger terminal connector to the negative (NEG, N,-) battery terminal.
- Connect the battery charger to a suitable electrical outlet. Do not face the battery when making this connection.
- When disconnecting, disconnect in the reverse sequence, removing the negative first (or positive first for positive ground systems).
Begin Charging
- Verify the voltage and chemistry of the battery.
- Confirm that you have connected the battery clamps or eyelet terminal connectors properly, and the AC power plug is plugged into an electrical outlet.
- [First time use] The charger will begin in Standby mode, indicated by an orange LED. In Standby, the charger is not providing any power.
- Press the mode button to toggle the NOCO Professional Battery Charger 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.
- The mode LED will illuminate the selected charge modee and the Charge LEDs will illuminate depending on the health of the battery.y) indicating the charging process has started.
- The charger can now be left connected to the battery at all times to provide maintenance charging.
Auto-Memory: The charger has built-in auto-memory and will return to the last charge mode when connected. To change modes after the first use, press the mode button.
Understanding Charge LEDs
Understanding Error LEDs
Error Conditions will be indicated by the following LEDs.
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 NOCO Professional Battery Charger 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. Temperature will also impact charging times. The GENIUSPRO50 Series features thermal compensation that automatically adjusts charging profiles to maximize charging performance.
