About NOCO Genius 2D
The Genius 2D is designed for charging the types of 12V lead-acid batteries, including Wet (Flooded), Gel, MF (Maintenance-Free) CA (Calcium), EFB (Enhanced Flooded Battery), and AGM (Absorption Glass Mat) batteries. It is suitable for charging battery capacities up to 40 Amp-hours and maintaining all battery sizes.
Getting Started
Before using the charger, carefully read the battery manufacture's specific precautions and recommended rates of charge for the battery. Make sure to determine the voltage and chemistry of the battery by referring to your battery owner's manual prior to charging.
Compatibility
The product is only compatible with 12-volt lead-acid batteries only. Do not attempt to use product with any other type of battery. Charging other battery chemistries may result in injury, death or property damage. Contact the battery manufacturer prior to attempting to charge the battery.

How to Use Noco Genius 2D
Charging Modes.
The Genius 2D has two (2) automatic modes, and will begin charging when both the battery and power are connected. Do not operate the charger until you confirm
the Genius 2D charger is compatible with your battery type and voltage. Below is a brief description:
Standby Mode : The charger is connected to AC power but no battery is detected, and the charger is not charging. Energy Save is activated during this mode,
drawing microscopic power from the electrical outlet.
12V NORM : For charging 12-volt Wet Cell, Gel Cell, Enhanced Flooded, Maintenance-Free, Calcium batteries and AGM. 14.5V | 2000mA | Up To 40Ah Batteries | Maintain all sizes
On-Board Mounting
Mount the charger near the battery, ensuring the cables and charger are secure and away from any moving parts (eg. fan blades, belts, pulleys). Secure the provided mounting bracket to the vehicle’s chassis using the two included self-tapping screws. For best results, mark the position using the bracket, and pre-drill two small pilot holes. Once the bracket is secured, use the velcro strap to secure the Genius 2D in place.
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 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.
- Connect the positive (red) eyelet terminal connector to the positive (POS,P,+) battery terminal.
- Connect the negative (black) eyelet terminal connector to the negative (NEG,N,-) battery terminal.
- Connect the battery charger’s AC power plug into a suitable electrical outlet.
Begin Charging.
- Verify the voltage and chemistry of the battery.
- Confirm that you have connected the eyelet terminal connectors properly and the AC power plug is plugged into an electrical outlet.
- All LEDs will flash momentarily, then the charger will begin charging without user intervention.
- The charger can now be left connected to the battery at all times to provide maintenance charging.
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:
| LED | Reason/Solution |
|---|---|
| Pulsing Red LED | The Red Charge LED will slowly pulse “on” and “off” when the battery is less than 75% fully charged. |
| Solid Green LED | When the battery is 100% charged, the Charge LED will be solid green. |
| Pulsing Green LED | The Green Charge LED will slowly pulse “on” and “off” when the battery is between 75% and 100% charged and during battery optimization charging. It is normal for optimization charging to occur on a regular basis after the battery is fully charged. |
Troubleshooting Leds
The Error, Hot, and Standby LEDs together shall indicate error conditions shown in the table below:
| Error | Reason/Solution |
|---|---|
| Error LED | Reverse polarity. Reverse the battery connections. Or battery voltage is too low for charger to detect. |
| Hot LED | Charger is outside of its safe operating temperature and is not charging. Allow charger to cool down. |
| Single alternating flash - Error and Standby |
Battery will not hold a charge. Have battery checked by a professional. |
| Double alternating flash - Error and Standby |
Possible battery short. Have battery checked by a professional. |
| Triple alternating flash - Error and Standby |
Battery voltage is too high for the selected charge mode. Check the battery. |
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 (AH) | Approximate Time to Charge In Hours (12 V) |
|---|---|
| 8 | 2 |
| 12 | 3 |
| 24 | 6 |
| 40 | 10 |
