NOCO GEN Vs. GX: The Similarities
Battery Types and Chemistries
Coming from the same brand, these GEN and GX battery chargers have similar features. The first one is that they support lead-acid and lithium-ion batteries of gel, flooded, deep cycle, AGM, and chemistries. It means that if you have a wet cell or flooded battery, you can find a suitable charger for it from one of the chargers in either series.
Automatic Charging
All battery chargers from the GEN and GX series automatically scan the battery’s condition before initiating charging. This means that the charger will only charge the battery if it needs charging. The battery analyzes the current level of charge and provides the ideal level of power according to the battery’s condition.
Thermal Compensation
Another essential feature of these NOCO battery chargers is thermal compensation. Each battery charger comes with a thermal monitor to determine the ambient temperature.
As you know, outdoor temperatures can affect how a battery needs charging. In this case, the charger reads ambient temperatures and adjusts the current so that it won’t undercharge a battery in cold weather under -4°F or overcharge it in hot weather at over 104°F.
Battery Detection and Force Mode
GEN and GX battery chargers can detect batteries as low as 1-volt. However, if the battery is dead, you can choose the Force Mode on the GEN series or the Supply Mode on the GX series to deliver a little more power than rated to supply zero voltage batteries.
Desulfation Mode
In this mode, NOCO allows you to repair undercharged batteries with sulfation inside. As such, the charger can recover a worn-out battery by removing some of the sulfation. This process helps to restore some of the capacity depending on the damage. Hence, if you have a battery sitting idle for a while, you have a chance of getting the correct capacity reading.
Safety Features
Being high voltage, high current chargers, NOCO has gone the extra mile to include the highest level of protection for its users. The GEN series comes with completely sealed cases that are waterproof, and saltwater tested. They also have an IP68 rating against dust, dirt, and sand.
On the other hand, the GX series has a die-cast aluminum case that acts as a heat sink. The case can withstand falls, vibrations, and different types of heavy industrial abuse.
Additionally, GEN and GX battery chargers all have Over Current, Open Circuit, and Over Voltage protection. Not to mention, they provide reverse polarity protection and apply spark-proof technology. Also, all these chargers integrate a fuse with a higher amperage rating than the gadget’s amp rating.
NOCO Genius GEN Vs. GX: The Differences
Charging Volts
NOCO GEN and GX may have similarities, but their differences define each series. Charging volts is the first difference you will notice in the two series.
GEN battery chargers are designed for 12-volt boat, marine, deep-cycle, and starter batteries. Meanwhile, GX chargers are for 24-volt, 36-volt, and 48-volt lead-acid and lithium-ion battery systems.
Charge Modes
Now, this is the feature that sets these battery chargers apart. Looking at the GEN series, you get five modes, while the GX series has six selections. What’s more, GEN chargers use one button for cycling through the functions, while GX chargers allow you to press on each mode. This feature presents GX as much easier units to use since you only need to press once for a feature.
GEN Charge Modes
- 12V: This mode is ideal for gel, wet cell, enhanced flooded, calcium, and maintenance-free batteries.
- 12V AGM: All 12V AGM batteries will require this mode on a GEN battery charger.
- 12V Lithium: For lithium-ion with battery management systems (BMS), including lithium-ion phosphate, this is the mode you will select.
- 12V Repair Mode: If you have an old, idle, or damaged battery that is stratified or sulfated, you will need this mode to restore its capacity. While not all batteries can be recovered, it gives them the chance to receive a full charge. This is because stratified and sulfated batteries tend to provide a false voltage reading. The 12V Repair function requires you to charge the battery fully and then use the Repair Mode to attempt the recovery process. It takes approximately four hours to complete battery repair, and then the charger will go back to Standby mode.
- Force Mode: This function detects and charges batteries down to 1-volt. It can also be turned on manually to charge any battery from zero volts.
GX Charge Modes
- Normal: This feature is for regular lead-acid batteries. It’s ideal for gel cell, wet cell, enhanced flooded, calcium, or maintenance-free batteries.
- Cold/AGM: This mode is for typical AGM batteries or if you’re charging an industrial battery in temperatures below 50°F. A blue indicator illuminates when you select this function.
- AGM+: Enhanced/ advanced AGM batteries that need a higher voltage than normal use this mode.
- Lithium-Ion: As it indicates, this feature is for lithium-ion batteries, including lithium-ion phosphate batteries.
- Repair: Again, this mode helps recover old, damaged, sulfated, or stratified batteries to their capacities.
- Supply Mode: When you select this feature, the charger converts power to DC for zero voltage battery charging. It can jumpstart a dead battery or troubleshoot a low-voltage battery. In addition, this mode can equalize an unbalanced battery system hence prolonging its lifespan.
Advanced Diagnostics
Each of the series has a different way of indicating potential battery problems. There are LED indicators for the Standby Mode, Bad Battery, High Voltage, and Reverse Polarity.
GEN Series Error LEDs
- Standby Mode: When this feature turns on, it indicates that the charger is powered, but it cannot detect a battery. This could be that the battery is not connected or the battery’s voltage is too low. If you’ve connected the battery, you will need to use the Force Mode to start charging manually.
- Bad Battery: This indicator tells you that the battery cannot hold a charge or there’s a possible short. If it’s the former, it’s best to have the battery checked by a professional.
- High Voltage Indicator: This feature shows you that the voltage is too high for the charge mode you’ve chosen. Hence, you will need to check the battery’s voltage and select the correct charge mode.
- Reverse Polarity: If you connect the battery to the charger in reverse, the Reverse Polarity will light up. Thus, you have to disconnect the charger from the battery and connect it to the correct terminals.
- Three Error Lights: Sometimes, three error lights will start flashing. It indicates that the charger’s temperature is too low or too high to operate optimally. You’ll have to wait for the charger to warm up or cool down to the operating limits.
GX Error Lights
This series uses flashing LEDs to indicate problems.
- Single Flash: This indicator shows that the battery cannot hold a charge. You need to have it checked by a qualified technician.
- Double Flash: Two continuous flashes are what you will see when there’s a possible battery short.
- Triple Flash: This is the high-voltage indicator that shows you’ve selected a mode that is too high.
- Solid Red LED error: It indicates reverse polarity.
- Standby Solid Orange: The charger is in supply mode, or the battery’s voltage is too low. You may need to check the inline fuse if the charger cannot get out of the supply mode or jumpstart the battery.
Warranty
When you buy a NOCO GEN battery, you can rest assured that the product is under a 3-year warranty, and the GX battery charger has a one-year warranty. After buying the charger, all you have to do is register the product by creating an account on the company’s official website. Thus, in case you have a warranty claim, it’s easier to fill out the necessary details.
