Noco genius1 vs Battery Tender Junior vs Ctek 0.8

NOCO GENIUS1, Battery Tender Junior, and CTEK 0.8 are car battery chargers that help jump-start a vehicle that has a dead battery back to its regular operation. In other words, the chargers refer to trickle chargers that act like jumper cables as they charge the car battery lightly for a short time.

The trickle chargers are smart enough to disconnect themselves from the power source when the car battery they are charging is complete, and they know the amount of power that particular battery needs. The article below discusses the similarities and differences of the NOCO GENIUS1, Battery Tender Junior, and CTEK and the best charger among the three.

Differences between NOCO GENIUS1, Battery Tender Junior and CTEK 0.8

The three chargers perform the same function of charging car batteries slowly for a while and make them suitable for providing power to the car. However, they have some features that distinguish them from one another. The differences include:

1. Shape, size and weightNOCO GENIUS1 vs Battery Tender Junior vs CTEK 0.8

The three chargers are both small but have different textures and pres


entations. The Battery Tender Junior is the heaviest in this case as it weighs about 1.8 pounds when the measurements are 8 inches by 4 inches by 9 inches. It is a cube in shape but very heavy to the extent you cannot lift it with one hand.

CTEK is the largest among the three chargers as it measures 9 inches by 4.75 inches by 11 inches but has a weight of 1.4 pounds. It is more prominent in size but lighter than the Battery Tender Junior, making it simple to handle as one can carry in a pocket or bare hands.

Lastly, the NOCO GENIUS1 is the smallest of all, such that it has measurements of 8 inches by 4 inches by 9 inches and has a weight of 15 pounds. The three chargers support fixing the chargers in-wall power supplies and leaving when there is frequent charging since they have eyelet connectors that allow one to leave the battery.

2. Importance and their characteristicsImportance and their characteristics

The three chargers have the same features. They have short jumper cables and crocodile clips that help connect with the battery with some connectors for frequent connection to occur or instead when you want to give the battery time to charge with its connection.

However, they have differences in their features, too, such that the NOCO GENIUS1 has a force able to force a dead battery that has zero charge to charge from this state until it gains charge that can start a car. Moreover, the charge it accumulates can still keep the battery for use for a longer time. It can also charge a battery with 6 volts since it is a multipurpose charger to charge multiple batteries.

Even though the three chargers charge a battery and set the power flow according to the size, state, and kind of battery, the NOCO GENIUS1 and the CTEK can set the power flow to prevent it overcharging due to the temperature changes. In areas with low temperatures, it is advisable to use NOCO GENIUS1 and CTEK since they are more muscular.

3. Currently, it supportsCurrently, it supports

The chargers support different currents depending on the type of vehicle that the battery needs to charge. NOCO GENIUS1 is the strongest in this case, and it supports vehicles with a current of about 30Ah and takes more time, of three or more days, to charge the battery fully.

The other chargers support batteries with 12 volts which are the standard volts for any other car. Still, the currents they give differ as the ACTEK contains 0.8A, Battery Tender Junior gives 0.75A, as the NOCO provides 1A, making it more substantial.

4. Maintenance and reconditioning

The batteries differ in their ability to maintain the battery and recondition it. NOCO and CTEK chargers can recondition the battery without necessarily keeping it but allow it to work for long. At the same time, the Battery Tender Junior can maintain the battery, which makes the lifespan of the battery longer.

Similarities between NOCO GENIUS1, Battery Tender Junior and CTEK 0.8Similarities between NOCO GENIUS1, Battery Tender Junior and CTEK 0.8

Since the three chargers have one common purpose of bringing back the car to its normal operations, they have to be the same at some point when working. Below are the common characteristics that make them similar.

  • Ability to charge

The three chargers can charge any battery without necessarily being a vehicle’s battery. They can charge batteries in the motorcycle, automotive, and marine and maintain batteries that need vital amounts of power. When considering the ability to charge, the main terms are the charging currents and the result’s voltage.

NOCO GENIUS1 contains an amp with an end voltage of 12 or 6 volts but differs with the type of unit using the charger. The Battery Tender Junior has currents for charging of about 0.75amp and an end voltage of 12 volts. Lastly, the CTEK 0.8 currents for charging are 0.80amps and an output voltage of about 12 volts. The three chargers are all excellent products for charging batteries. However, the NOCO GENIUS1 is the most robust battery to use for charging.

  • Precautions to take for safety measures

The three chargers have characteristics that help them maintain the safety measures from damages. For example, the chargers have features that help prevent the battery from overcharging when the terminals are in the wrong position and help in charging.

Secondly, the chargers can resist dirty particles from accumulating in them that help prevents moisture in the battery that can damage the battery surface from rust that results from the reactions between the moisture and the metal surface.

To reduce the chances of damage when charging or discharging, the chargers have reverse polarity protection such that they can reverse the amount of current when it is in excess. In addition, since the batteries are intelligent chargers, they can disconnect from the battery when the battery is full and maintain the battery until it is almost complete.

When the batteries have any damage, the chargers can protect them by detecting them when charging. The chargers notify the user when the battery has damages by producing flashlights. The chargers have seals in their cases that mainly protect the charger from sparks that can cause a fire. It is advisable to use the chargers at places that are away from fire since they are flammable.

The best trickle battery charger

The most preferred charger is NOCO GENIUS1 which is NOCO GENIUS1 Amp 6V and 12V charger. Due to its fast charging speed and force feature to charge a completely dead battery.


The article above discusses the similarities and the differences between the three chargers. The comparison helps one decide on what type of charger to buy for the best use. NOCO GENIUS1 charger is the best for use. It helps maintain the car battery as it can charge a dead battery. Battery Tender Junior is cheap and affordable to buy by everyone, but it cannot regulate the temperatures when they are cold, but it can detect them. Finally, the CTEK charger maintains the charger lifespan bay making it longer and is best for use in the house.

Consider checking the prices and more features with the three chargers at amazon shops or sites that display clear images of the chargers with their distinctive features. The chargers are affordable to everyone since they differ in size and price too. The NOCO GENIUS1 is the most expensive in this case.

Taking a quick look at the Noco Genius 1. Great little smart charger for keeping batteries charged while in storage. Always read the instruction manual! Not liable for any damages to your vehicle.
