Key differences between Noco Genius 2, Noco Genius 5 and Noco Genius 10Noco Genius2 vs Genius5 vs Genius10

i. Charging rate

Only Noco Genius 10 can be used as a 12v 10-ampere power supply. Also, the 12V Direct current supply mode allows power flow via the Noco Genius 10 cable to power all devices with 12 voltages, and the 12V supply mode is essential when testing other machines.

ii. Size and measurements

Some differences can be easily seen despite the Noco Genius battery chargers having the same appearance and design, especially the Genius 2 and Genius 5. The more advanced version, which is Noco Genius 10, is bigger than the other panel. Also, the front panel where the model number is positioned is a bit different from Genius 2 and Genius 5.

In terms of size, each charger has different measurements. For instance, Noco Genius 10 is larger with approximately 10 inches and above and around one or two inches larger in depth and width. Noco Genius 5 and 2 are a bit smaller than Genius 10, with Genius 5 having a length of approximately 7 inches. Genius 2 is the smallest, with a length of roughly 4 to 6 inches.

iii. Charging time for each charger

The time taken for the charger to completely charge a battery varies depending on the size and the output ampere. For example, a 12V device with a battery size of around 45Ah charging time will vary depending on the type of charger. If it is a Noco Genius 10, the time taken to charge the battery fully is approximately 3 to 3.6 hours.

If it is Genius 5, the time will be more than Genius 10. It will take approximately 4.5 to 6.5 hours until the battery is fully charged. Genius 2 has a slower charging rate than others; hence, it will take more time to charge the battery fully. The charger will take up to 16 hours, but the battery will not drain power faster when compared to Genius 10.

iv. Batteries supported by chargers

All the three chargers support different batteries depending on the amperes, although all will support six voltages and 12 voltages batteries. Noco Genius 2 supports batteries ranging from 4Ah to around 40 Ah since the charger transmits low power. For Genius 5, it supports batteries ranging from 45 to around 120Ah, and finally, Genius 10 supports batteries of more current, which is 230 Ah.

Among all the three chargers, only the Noco Genius charger can charge 6V AGM batteries and not the other two. The charging ability uniquely identifies the Noco Genius battery 10.

Standard features among Noco Genius 2, Noco Genius 5 and Noco Genius 10Standard features among Noco Genius 2, Noco Genius 5 and Noco Genius 10

The chargers usually perform the same functions, and they also have the same features since the same manufacturers manufacture them from the same company.

  • Polarity protection

Most batteries experience reverse polarity. All three chargers can prevent the occurrence of reverse polarity, thus keeping the battery in good condition.

Also, all three charges can protect the batteries from overcharging. The chargers detect battery issues, especially when the battery is fully charged or when it is overused. When the battery is fully charged, the chargers detect and automatically shut off, preventing power from flowing from the power supply source to the battery. The safety feature keeps the battery in good condition and increases its lifespan.

When handling the lead-acid batteries, ensure you are careful by fooling the recommended guidelines. Avoid charging the car battery near flammable materials such as flammable liquids and gases.

Also, the Noco Genius printed number has a slightly different front panel, while the other two have the same front panel.

  • Thermal sensors

Thermal sensors are essential in detecting when the battery is complete and is overcharging or when the battery is not charging, or when there is limited power transmission from the power supply source to the battery. All chargers have new advanced thermal sensors that have a significant impact on the battery’s charging capacity.

  • Charging capability

All three Noco Genius chargers can charge both lithium-ion batteries and lead-acid batteries. They all charge approximately six voltages to around 12 voltages meaning they can charge any battery with the same voltage and require the same charger.

  • Warranty period

Each Noco Genius charger has a warranty of 3 years, and the warranty is the same. The warranty allows users to return a fault and be given a well-functioning charger to reduce the cost of purchasing a new charger. Once the warranty period is over, it is difficult to return a fault charger.

  • Improved features

Noco Genius company has manufactured advanced battery chargers with advanced features. For instance, the chargers can test the battery’s condition and alert the user when the battery is failing. Also, they have a connectivity feature to check if the battery voltage connection is good, test reverse polarity, and the chargers repair and upgrade the functioning of the battery.
