About GB40. The NOCO Genius® Boost™ GB40 is an ultra-compact and portable lithium-ion jump starter for cars, boats, motorcycles, ATVs, lawn mowers, RVs, tractors, trucks and more. It’s extremely safe for anyone to use. It features spark proof technology and reverse polarity protection. The GB40 can instantly jump start most single-battery applications, up to 20 times on a single charge. The GB40 is also equipped with a USB battery pack and LED flashlight, making it the ultimate emergency tool.
Getting Started. The GB40 comes partially charged out of the box and needs to be fully charged prior to use. Carefully read and understand the vehicle owner's manual on specific precautions and recommended methods for jump starting the vehicle. Make sure to determine the voltage and chemistry of the battery by referring to your battery owner's manual prior to using this product. The GB40 is for jump starting 12-volt lead-acid batteries only.
Connecting to the Battery.
Before connecting to the battery, verify that you have a 12-volt lead-acid battery. The GB40 is not suitable for any other type of battery. Identify the correct polarity of the battery terminals on the battery. The positive battery terminal is typically marked by these letters or symbol (POS,P,+).
The negative battery terminal is typically marked by these letters or symbol (NEG,N,-). Do not make any connections to the carburetor, fuel lines, or thin, sheet metal parts. The below instructions are for a negative ground system (most common). If your vehicle is a positive ground system (very uncommon), follow the below instructions in reverse order.
1.) Connect the positive (red) HD battery clamp to the positive (POS,P,+) battery terminal.
2.) Connect the negative (black) HD battery clamp to the
negative (NEG,N,-) battery terminal or vehicle chassis.
3.) When disconnecting, disconnect in the reverse sequence, removing the negative first (or positive first for positive ground systems).
Jump Starting.
1.) Verify the voltage and chemistry of the battery.
2.) Confirm the HD battery clamps are connected to the correct polarity battery terminals.
3.) Connect the HD X Connector to the GB40.
4.) Make sure all of the vehicle's power loads (headlights, radio, air conditioning, etc.) are turned off before attempting to jump start the vehicle.
5.) Press the Power Button to begin jump starting. All LEDs will flash, indicating that all LEDs are properly functioning. If you are properly connected to the battery, the White Boost LED will illuminate. If the battery clamps are connected in reverse, the Red Error LED will illuminate. Reverse the connections to clear this error and then the White Boost LED will illuminate. The White Boost LED is illuminated, when the GB40 is ready to jump start your vehicle.
6.) Try starting the vehicle. Most vehicles will immediately start. Some vehicles may require the GB40 to be connected for up to 30 seconds before starting. If the vehicle does not start right away, wait 20-30 seconds and try again. Do not attempt more than five (5) consecutive jump starts within a fifteen (15) minute period. Allow the GB40 to rest for fifteen (15) minutes before attempting to jump start the vehicle again.
7.) Once you have started your vehicle, disconnect the battery clamps, and remove the GB40.
Low Voltage Batteries & Manual Override
The GB40 is designed to jump start 12-volt lead-acid batteries down to 2-volts. If your battery is below 2-volts, the Boost LED will be “Off”. This is an indication that the GB40 can not detect a battery.
If you need to jump start a battery below 2-volts there is a Manual Override feature, which allows you to force “On” the jump start function.
CAUTION. USE THIS MODE WITH EXTREME CARE. THIS MODE IS FOR 12-VOLT LEAD-ACID BATTERIES ONLY. BOTH THE SPARK PROOF AND REVERSE POLARITY PROTECTION FEATURES ARE DISABLED. PAY VERY CLOSE ATTENTION TO THE POLARITY OF THE BATTERY BEFORE USING THIS MODE. DO NOT ALLOW THE POSITIVE AND NEGATIVE BATTERY CLAMPS TO TOUCH OR CONNECT TO EACH OTHER AS THE PRODUCT WILL GENERATE SPARKS. THIS MODE USES VERY HIGH CURRENT (UP TO 1000 AMPS) THAT CAN CAUSE SPARKS AND HIGH HEAT IF NOT USED PROPERLY. IF YOU ARE UNSURE ABOUT USING THIS MODE, DO NOT ATTEMPT AND SEEK PROFESSIONAL HELP.
Before using the Manual Override feature, make sure the HD battery clamps are connected to the correct polarity battery terminals and the HD X Connect is connected to the GB40. To use the Manual Override feature, press and hold the Manual Override Button (a red exclamation point icon inside a red circle) for three (3) seconds. The White Boost LED will flash “On” and “Off” indicating you have successfully entered into Manual Override and it is ready to jump start your vehicle. If connected in reverse polarity, the Red Error LED will illuminate and the unit will not operate.
CAUTION: POWER THE GB40 "OFF" BEFORE DISCONNECTING THE BATTERY CLAMPS. THIS WILL ENSURE YOUR SAFETY. REMEMBER BOTH THE SPARK PROOF AND REVERSE POLARITY PROTECTION FEATURES ARE DISABLED.
Most vehicles will immediately start. Some vehicles may require the GB40 to be connected for up to 30 seconds
before starting. If the vehicle does not start right away, wait 20-30 seconds and try again. Do not attempt more than five (5) consecutive jump starts within a fifteen (15) minute period. Allow the GB40 to rest for fifteen (15) minutes before attempting to jump start the vehicle again.
Understanding Charge LEDs.
The GB40 has four (4) Charge LEDs - 25%, 50%, 75% and 100%. These Charge LEDs indicate the internal battery's state-of-charge (SOC). See below:
| LED Explanation | |
25%Red LED25% 50% 75% 100% | The 25% Charge LED will ‘breath’ on/off while charging and will be solid Red when the internal battery is 25% charged. |
50%Red LED25% 50% 75% 100% | The 50% Charge LED will ‘breath’ on/off while charging and will be solid Red when the internal battery is 50% charged. |
75%Yellow LED25% 50% 75% 100% | The 75% Charge LED will ‘breath’ on/off while charging and will be solid Yellow when the internal battery is 75% charged. |
100%Green LED25% 50% 75% 100% | The 100% Charge LED will ‘breath’ on/off while charging and will be solid Green when the internal battery is fully charged.When connected to a USB charger, no other charge LEDs will be illuminated. Once disconnected from the charger, all four (4) Charge LEDs will be illuminated when the internal battery is between 75%-100%, and the unit is powered “ON”. |
