Charging the NOCO GB20
Proper charging is essential for maintaining the NOCO GB20’s performance and longevity. The GB20 comes partially charged and should be fully charged before its initial use. Use the included USB charging cable to connect the GB20 to a USB power source, such as a wall adapter or car charger; A NOCO 10W 12V power adapter is recommended for optimal charging.
The GB20 can also be recharged from any USB-powered port, but using a third-party adapter, ensure it’s compatible with USB 2.0 and meets safety standards. Low-quality adapters can pose electrical risks. The charging indicator LEDs will illuminate to show the charging progress. When all LEDs are solid, the GB20 is fully charged.
Avoid overcharging the GB20, as it can shorten the battery life. Disconnect the charger once it’s fully charged. Over time, an unused GB20 will discharge, requiring recharging before use. Avoid storing or using the GB20 in areas with high dust or airborne materials. Storing the device in a dry location is important. Prolonged skin contact with power adapters may cause injury, and they may become warm during normal use.
Jump Starting a Vehicle with the GB20
Jump-starting a vehicle with the NOCO GB20 is straightforward but requires careful attention to safety. Before starting, carefully read and understand your vehicle owner’s manual for specific jump-starting precautions. Ensure the GB20 is fully charged. Verify the vehicle’s battery voltage is 12V. Attach the red clamp to the positive (+) terminal of the vehicle’s battery and the black clamp to the negative (-) terminal or a suitable grounding point on the vehicle’s chassis.
Ensure a solid connection. If the GB20 detects a low voltage battery, the “Boost” LED might be off. In this case, the manual override function might be needed, but only use this feature if you are sure of your battery’s condition. Once properly connected, start the vehicle’s engine. If it doesn’t start immediately, wait a few minutes and try again.
After the vehicle starts, disconnect the clamps in reverse order: black first, then red. Store the GB20 in a safe, dry place. Always wear eye protection when jump-starting a vehicle. Avoid jump-starting a damaged or frozen battery. Work in a well-ventilated area to prevent build-up of explosive gases.
Manual Override Function: When and How to Use It
The manual override function on the NOCO GB20 is a powerful feature that should only be used in specific situations. It is designed to jump-start batteries that are so deeply discharged (below 2 volts) that the GB20 cannot automatically detect them. When the Boost LED is off, indicating the GB20 cannot detect a battery, the manual override can be engaged.
However, exercise extreme caution! Engaging manual override disables the GB20’s safety protections, such as reverse polarity protection and spark-proof technology. Ensure you have correctly identified the battery polarity before proceeding. To activate manual override, connect the GB20 to the battery. With the error light blinking, disconnect the red clamp. Press and hold the override button (!) for three seconds. Reattach the red clamp.
The Boost LED will illuminate, indicating override is active. Immediately attempt to start the vehicle. Do not leave the GB20 in override mode for extended periods. Once the vehicle starts, disconnect the GB20 immediately. Misuse of the manual override function can lead to battery damage, personal injury, or property damage. Only use it when absolutely necessary and with utmost care.
Safety Precautions and Warnings
Prior to using the NOCO GB20, it is crucial to thoroughly understand and adhere to all safety precautions and warnings outlined in the user manual. Failure to do so can result in serious injury, death, or property damage. The GB20 is an electrical device that can deliver a shock. Do not cut power cords or submerge the unit in water.
Explosions are possible if the GB20 is used with unmonitored, incompatible, or damaged batteries. Never leave the unit unattended while in use. Do not attempt to jump-start a damaged or frozen battery. Only use with 12-volt lead-acid batteries. Operate in well-ventilated areas. The GB20 emits heat and can cause burns. Avoid covering the unit and keep it away from combustible materials;
Always wear eye protection when operating the GB20, as batteries can explode and cause flying debris or battery acid exposure. Explosive gases are produced during normal battery operation; follow all safety information provided by the battery manufacturer. This product contains chemicals, including lead, known to cause cancer and reproductive harm. Wash hands after handling. If the battery is excessively hot, emitting an odor, or deformed, immediately stop use and contact NOCO.
Troubleshooting Common Issues
Encountering issues with your NOCO GB20 is not uncommon, and many problems can be resolved with simple troubleshooting steps. If the GB20 fails to charge, ensure the USB cable and power adapter are functioning correctly and properly connected. Try a different USB port or adapter to rule out a faulty component. If the unit powers on but doesn’t jump-start a vehicle, check the battery connections, ensuring they are clean and securely attached to the battery terminals.
A flashing error light often indicates reverse polarity or a battery voltage issue. Double-check that the clamps are connected to the correct terminals (red to positive, black to negative). If the battery voltage is too low (below 2V), the GB20 may not detect it. In such cases, the manual override function might be necessary, but use it with extreme caution, as it disables safety protections.
If the GB20 shuts down unexpectedly, it could be due to overheating. Allow the unit to cool down before attempting to use it again. For persistent problems, consult the NOCO support website or contact their customer service for further assistance. Remember to have your GB20 model number and purchase date readily available for faster support.
Low Voltage Battery Detection
The NOCO GB20 is engineered to jump-start 12-volt lead-acid batteries. However, it incorporates a safety feature that prevents operation when connected to severely discharged batteries. Specifically, if your battery’s voltage is below 2 volts, the GB20’s Boost LED will remain off, indicating that it cannot detect the battery. This is a crucial safety measure to prevent potential damage to both the GB20 and the vehicle’s electrical system.
When the GB20 fails to detect a low-voltage battery, it signifies that the unit is unable to automatically initiate the jump-starting process. In such scenarios, the manual override function might be considered, but it should only be used with extreme caution and a thorough understanding of the risks involved. Engaging the manual override disables the GB20’s safety protections, potentially leading to sparks, fire, or damage if not used correctly.
Before resorting to the manual override, it’s advisable to double-check the battery connections, ensuring they are clean and secure. If the battery is indeed below 2 volts, it might be excessively damaged and require professional attention or replacement. Always prioritize safety and consult the vehicle’s owner’s manual for specific instructions and precautions related to jump-starting.
Maintenance and Storage Tips
To ensure the longevity and optimal performance of your NOCO GB20, proper maintenance and storage are crucial. After each use, inspect the unit for any signs of damage, such as cracks in the casing or frayed cables. Clean the clamps with a dry cloth to remove any dirt or corrosion. Avoid using water or cleaning solvents, as they can damage the internal components.
When storing the GB20, choose a dry and cool location, away from direct sunlight and extreme temperatures. The ideal storage temperature range is between -20ºC to 50ºC, with a daily average between 0ºC and 25ºC. Avoid storing the unit in areas with high humidity or dust concentrations. Before long-term storage, fully charge the GB20 to maintain its battery health.
It is recommended to recharge the GB20 every three to six months, even when not in use, to prevent the battery from self-discharging excessively. Over time, an unused GB20 will discharge and must be recharged before use. When charging, use the included USB cable and a compatible power adapter. Avoid overcharging the unit for extended periods, as this can shorten the battery life. Always store the GB20 on a flat, secure surface to prevent it from falling and sustaining damage.
