How To Use

Charging Modes.
The GENIUS2 has six (6) modes: Standby, 12V, 12V AGM, 12V LITHIUM, 6V and Force. 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. Always check with battery manufacturer to confirm the right charge mode for your specific battery. Do not operate the charger until you confirm the appropriate charge mode for your battery. Below is a brief description:

Using 6V. [Press & Hold for 3 seconds]
6V charge mode is designed for 6-volt lead-acid batteries only, like Wet Cell, Gel Cell, Enhanced Flooded, Maintenance-Free and Calcium batteries. Press and hold for three (3) seconds to enter 6V Charge Mode. Consult the battery manufacturer before using this mode.

Using 12V Lithium.
12V Lithium charge mode is designed for 12-volt lithium-ion batteries only, including lithium iron phosphate.

CAUTION. USE THIS MODE WITH EXTREME CARE. THIS MODE SHOULD ONLY BE USED WITH 12-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.

Force Mode. [Press & Hold for 5 seconds]
Force mode allow 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, then select the appropriate mode. All available modes will flash. Once a charge mode is selected, the Charge Mode LED and Charge 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.

CAUTION. USE THIS MODE WITH EXTREME CARE. FORCE MODE DISABLES SAFETY FEATURES AND LIVE POWER IS PRESENT AT THE CONNECTORS. ENSURE ALL CONNECTIONS ARE MADE PRIOR TO ENTERING FORCE MODE, AND DO NOT TOUCH CONNECTIONS TOGETHER. RISK OF SPARKS, FIRE, EXPLOSION, PROPERTY DAMAGE, INJURY, AND DEATH.

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. The positive battery terminal is typically marked by these letters or symbol (POS, P, +). The negative battery terminal is typically marked by these letters or symbol (NEG, N, -). Do not make any connections to the carburetor, fuel lines, or thin, sheet metal parts.

FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE.

WARNING: A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY:

1. Position AC and DC cords to reduce risk of damage by hood, door, or moving engine part.
2. Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
3. Check polarity of battery terminals. The POSITIVE (POS, P, +) battery terminal usually has a larger diameter than the NEGATIVE (NEG, N, -) battery terminal.
4. Determine which battery terminal is grounded (connected) to the chassis. If negative battery terminal is grounded to chassis (as in most vehicles), see Step 5. If positive battery terminal is grounded to the chassis, see Step 6.
5. For negative-grounded vehicle only, connect POSITIVE (RED) battery clamp or eyelet terminal connector from battery charger to POSITIVE (POS, P. +) ungrounded battery terminal. Connect NEGATIVE (BLACK) battery clamp or eyelet terminal connector to vehicle chassis or engine block away from battery. Connect to a heavy gauge metal part of the frame or engine block.
6. For positive-grounded vehicle only, connect NEGATIVE (BLACK) battery clamp or eyelet terminal connector from battery charger to NEGATIVE (NEG, N, -) ungrounded battery terminal. Connect POSITIVE (RED) battery clamp or eyelet terminal connector to vehicle chassis or engine block away from battery. Connect to a heavy gauge metal part of the frame or engine block.
7. Connect the battery charger into a suitable electrical outlet. Do not face the battery when making this connection.
8. When disconnecting the battery charger, disconnect in the reverse sequence, removing the negative first (or positive first for positive ground systems).

FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE. WARNING: A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY

1. Check polarity of battery terminals. The POSITIVE (POS, P, +) battery terminal usually has a larger diameter than the NEGATIVE (NEG, N, -) battery terminal.
2. Attach at least a 24-inch-long 6-gauge (AWG) insulated battery cable to NEGATIVE (NEG, N, -) battery terminal.
3. Connect POSITIVE (RED) battery clamp or eyelet terminal connector from battery charger to POSITIVE (POS, P. +) battery terminal.
4. Position yourself and free end of cable as far away from battery as possible – then connect NEGATIVE (BLACK) battery clamp or eyelet terminal connector to free end of cable.
5. Connect the battery charger into a suitable electrical outlet. Do not face the battery when making this connection.
6. When disconnecting charger, always do so in reverse sequence of connecting procedure and break first connection while as far away from battery as practical. 7.) A marine (boat) battery must be removed and charged on shore. To charge it on board requires equipment specially designed for marine use.

Begin Charging.

1. Verify the voltage and chemistry of the battery.
2. Confirm that you have connected the battery clamps or eyelet terminal connectors properly and the AC power plug is plugged into an electrical outlet.
3. [First time use] 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.

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.

Charging Times

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. Temperature will also impact charging times. The GENIUS2 features thermal compensation that automatically adjusts charging profiles to maximize charging performance.

Understanding Charge LEDs.

Understanding Error LEDs
Error Conditions will be indicated by the following LEDs.

1. Mode Button Push to cycle through charging Modes.
2. Overvoltage Error LED Illuminates solid Red; Battery Voltage is above Protect voltage.
3. Bad Battery Error LED Illuminates solid Red when connected battery will not hold a charge.
4. Reverse Polarity Error LED Illuminates solid Red when reverse polarity is detected.
5. Standby LED Illuminates when the charger is in Standby Mode, the charger is not charging or providing any power to the battery.
6. Charge LED indicates the connected battery(s) state-of-charge.
7. Mode LED Indicates the Charge Mode the charger is currently in. Push the MODE button to cycle through charge Modes.
8. [Press and Hold] Mode LED Mode button must be pressed and held for 3 seconds to enter the mode.
