Description

The Noco 1-Amp Battery Charger GENIUS1 is engineered with advanced technology to provide safe and efficient battery charging. It features an automatic charging mode that adjusts the charging rate based on the battery's state of charge, ensuring optimal charging without overcharging. The manual mode allows for more control, making it suitable for deep discharge recovery. The charger also includes multiple safety features such as overcharge protection and reverse polarity protection to prevent damage to both the charger and the battery.

How To Use Noco 1-Amp Battery Charger GENIUS1

Charging Modes
The GENIUS1 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. The below instructions are for a negative ground system (most common). If your vehicle is a positive ground system (very

uncommon), follow the below instructions in reverse order.

1. Connect the positive (red) battery clamp or eyelet terminal connector to the positive (POS,P,+) battery terminal. 
2. Connect the negative (black) battery clamp or eyelet terminal connector to the negative (NEG,N,-) battery terminal or vehicle chassis. 
3. Connect the battery charger into a suitable electrical outlet. Do not face the battery when making this connection.
4. When disconnecting the battery charger, disconnect in the reverse sequence, removing the negative first (or positive first for positive ground systems).

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

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 GENIUS1 features thermal compensation that automatically adjusts charging profiles to maximize charging performance.

Understanding Charge LEDs
The charger has one (1) Charge LED. This Charge LED indicates the connected battery(s) state-of-charge (SOC). 

See the explanation below:

Understanding Error LEDs

Error Conditions will be indicated by the following LEDs. 

LED	Reason/Solution
Solid	Charger is in Standby mode or Battery voltage is too low for charger to detect.
Solid	Battery voltage is too high for the selected charge mode / Check the battery and charge mode.
Solid	Possible battery short / Battery will not hold a charge. Have battery checked by a professional.
Solid	Reverse polarity / Reverse the battery connections.
Flashing	Charger internal temperature too high / Charger will resume function once the Charger internal temperature drops. Charger ambient temperature too cold / Charger will resume function once the Charger ambient temperature rises.

Setup Guide

To operate the Noco 1-Amp Battery Charger GENIUS1, follow these steps:
