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).

USE THIS MODE WITH EXTREME CARE. THIS MODE SHOULD ONLY BE USED WITH 6-VOLT, 12-VOLT 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 and 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 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 output load exceeds the 25A current limit.

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 given the opportunity 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 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 size and condition of the battery, however battery temperature must be closely monitored.

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, 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.

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.

Using Reduced Charge Current Mode

[Press the 10A Mode Button]

Reduced Charge Current mode will 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. 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.

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.

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