NOCO Genius Vs. Genius PRO: The Differences?

Charging Volts

The charging voltage differs between NOCO Genius and NOCO Genius Pro. NOCO Genius automotive battery chargers are compatible with either 12V or 6V batteries, while NOCO Genius Pro supports 6V, 12V, and 24V batteries. If you are looking for a battery charger and maintainer for your heavy-duty vehicle, choose NOCO Genius Pro.

Charge Modes

Charge modes also vary between NOCO Genius Pro and NOCO Genius, but it depends on the particular product. NOCO Genius1, Genius2, Genius2X2, and Genius2X4 have 6V and 12V, 12V AGM, and 12V Lithium charging modes. However, Genius2D is only compatible with 12V batteries. Genius5 and Genius10 have an additional 12V repair mode for repairing old, idle, damaged, stratified, or sulfated batteries. The Genius10 also has the 12V supply mode for supplying DC voltage needed to power any 12V equipment.

The NOCO Genius Pro battery chargers have more charging modes than NOCO Genius. The GeniusPro25 and GeniusPro50 have additional 6V AGM, 6V Lithium, 6V Repair, 24V AGM, 24V Lithium, and 24V Repair modes. They also have 12V and 24V DC separate outlets for supplying equipment requiring such voltages.

Dual Voltage

NOCO Genius battery chargers don’t have a dual voltage power supply. In fact, only Genius10 has a single 12V power supply. All other Geniuses don’t have a power supply mode. NOCO GeniusPro25 and GeniusPro50 have a dual 12V and 24V DC voltage supply for powering instruments and equipment requiring such voltages.

Reduced Charge Current Mode

NOCO Geniuses don’t have the reduced charge current mode. This mode allows the battery charger to operate at a lower charge current for batteries with smaller capacities or maintenance. GeniusPro50 has 10A reduced charge mode, while GeniusPro25 has 5A reduced charge modes.

Charge Levels

NOCO Genius and NOCO Genius Pro have 6 charging levels. They both indicate when the battery is below 25% charged, 50% charged, 75% charged, and 100% charged. Also, when the charge is complete, both show a solid green LED.

The difference in charging levels is at the optimization level. In NOCO Genius, this mode is shown by a pulsating green LED, indicating that the bulk charge is complete and the battery is optimized for extended life. This is equivalent to the 100% charged mode in Genius Pro.

In NOCO Genius Pro, optimization is shown by the LED bar that turns off once the optimization is complete. It is the equivalent of maintenance in NOCO Genius. This charging mode allows the battery chargers to be connected to the battery indefinitely.

Advanced Diagnostic

For NOCO Geniuses 1, 2, 5, and 10, advanced diagnostics include high voltage, bad battery, reverse polarity, standby mode, and temperature. Any of these states or issues will be indicated by the respective LEDs. For high or low temperatures, all error LEDs flash. The battery charging will only resume when the temperature is back to the operating limits. Other NOCO Geniuses also have these advanced diagnostic functions, but the indication is different. You should check the product you buy to understand it.

NOCO GeniusPro25 and Pro50 also have the same diagnostic functions. The only difference is how low and high temperatures are indicated. For NOCO Genius Pros, a red thermometer LED illuminates if the charger’s internal temperature is high. It informs you that the charging has been stopped and will resume once the temperature goes down. If the ambient temperature is too low, all error LEDs flash.
