How To Use

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 the 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:

NOCO GENIUS1 1-Amp Smart Battery Charger User Guide 1

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. 1

2V 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 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 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 symbols (POS, P, +). The negative battery terminal is typically marked by these letters or symbols (NEG, N, -). Do not make any connections to the carburetor, fuel lines, or thin sheet metal parts.

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

  1. Position the AC and DC cords to reduce the risk of damage from the hood, door, or moving engine parts.
  2. Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
  3. Check the polarity of the 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 the negative battery terminal is grounded to the chassis (as in most vehicles), see Step 5. If the positive battery terminal is grounded to the chassis, see Step 6.
  5. For a negative-grounded vehicle only, connect the POSITIVE (RED) battery clamp or eyelet terminal connector from the battery charger to the 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 a positive-grounded vehicle only, connect the NEGATIVE (BLACK) battery clamp or eyelet terminal connector from the battery charger to the NEGATIVE (NEG, N, -) ungrounded battery terminal. Connect the POSITIVE (RED) battery clamp or eyelet terminal connector to the vehicle chassis or engine block away from the battery. Connect to a heavy-gauge metal part of the frame or engine block.
  7. Connect the battery charger to 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).

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.NOCO GENIUS1 1-Amp Smart Battery Charger User Guide 2

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.

The NOCO Genius1 is a compact, energy-efficient smart charger designed for 6V and 12V lead-acid batteries (flooded, gel, AGM, maintenance-free) as well as 12V lithium-ion batteries. It works for cars, motorcycles, ATVs, boats, lawnmowers, and more.

Q2. How does a smart battery charger like NOCO Genius1 work?

Unlike traditional chargers, smart chargers automatically diagnose, recondition, recharge, and maintain batteries. They adjust charging levels to protect battery life and prevent overcharging.

Q3. What types of batteries can the NOCO Genius1 charge?

It can charge and maintain:
6V & 12V lead-acid batteries (flooded, gel, AGM, MF)
12V lithium-ion batteries
This makes it versatile for vehicles, power equipment, and marine batteries.

Q4. Can the NOCO Genius1 revive a dead battery?

Yes. Using Force Mode, the Genius1 can charge batteries as low as 1 volt, which many chargers cannot do.

Q5. How long does it take to charge a battery with the NOCO Genius1?

Charging speed depends on battery size:
20Ah motorcycle battery → ~15 hours
40Ah lawn mower battery → ~30 hours
80Ah car battery → ~60 hours
100Ah truck battery → ~75 hours

Q6. Can a 1-amp charger fully charge a car battery?

Yes, but it will take a very long time. A 1-amp charger is best for small batteries or for maintenance charging of car batteries.

Q7. Can I leave the NOCO Genius1 connected all the time?

Yes. It’s designed to be left connected safely. The charger automatically switches to maintenance mode once the battery is full, preventing overcharging.

Q8. How do I know if my NOCO Genius1 is charging?

The built-in LED indicators show charging status, errors, and when the battery is fully charged.

Q9. Can the NOCO Genius1 overcharge a battery?

No. It constantly monitors voltage and switches to float/maintenance mode once the battery is full, preventing overcharging.

Q10. What are the 7 stages of charging in NOCO chargers?

The charging process goes through: Desulfation → Soft Start → Bulk → Absorption → Analysis → Recondition → Float/Maintenance. This ensures a complete and safe charge.
