Not Charging and Solution

Not Working and Solution
Fix not charging: If your Noco GB40 Genius Boost is not charging properly, try replacing the battery. If that does not fix the issue, it may be due to a defective charger. In that case, please reach out to our support team for a replacement charger.
Clicking Noise and Solution
Some jump starters make clicking noises when they’re charging. This is usually because the battery is too cold or too hot. To fix this problem, warm up the battery before trying to charge it. Alternatively, try using a different type of charger for your jump starter.
Flashing Red & Green and Solution
If your NOCO GB40 is flashing red and green, there are a few things you can do to try and fix the issue. First, check the battery level and make sure it is charged. If the battery is low, charge it for a few hours and then try again. If the battery is charged, try resetting the device by pressing and holding the power button for 10 seconds. If the GB40 still won’t stop flashing red and green, contact NOCO customer support for help.
The chords on clamps are very short
Your NOCO GB40 chords on clamps are very short, there are a few things you can do to fix the issue. First, try to adjust the clamps so that they are not so tight. This will give the chords some slack and allow you to stretch them out a bit. If this does not work, you can try using a wire cutter to cut the chords. Be sure to cut them as close to the clamps as possible so that you do not damage the clamps.
Lack of a wall charger for recharging
Because of your NOCO GB40 jump starter doesn’t come with a wall charger, you can use a USB cable to recharge it. Just connect the USB cable to the GB40 and then plug it into a USB power source. You can use a USB port on your computer or a USB power adapter.
It’s also important to make sure that the GB40 is properly connected to the power source. The red charging indicator light should be lit up when the GB40 is connected to a power source. If the red light is not lit, check the connections and make sure that the GB40 is properly plugged into the power source.
Once the GB40 is properly connected to a power source, the red charging indicator light will turn off when the GB40 is fully charged.
Restricted to 12-volt lead-acid batteries
First, you’ll want to check the battery terminals to make sure that they are clean and free of corrosion. If the terminals are corroded, you can clean them with a wire brush or by using a solution of baking soda and water.
Next, you’ll want to check the connections between the charger and the battery. Make sure that the connections are tight and secure.
Finally, you’ll want to check the charger itself to make sure that it is working properly. If the charger is not working properly, you may need to replace it.
Limited capacity and number of ports
First, try resetting the device. To do this, simply remove the battery and then reinsert it. This should reset the device and hopefully fix the issue.
If that doesn’t work, then you may need to update the firmware on the device. You can do this by downloading the latest firmware from the NOCO website and then following the instructions on how to update the firmware.
If neither of those solutions work, then you may need to contact NOCO customer support for further assistance.
Only has 5V ports
First, check to make sure that the charging cable is properly connected to the GB40. If the cable is loose or not properly connected, this could be the reason why the GB40 is only outputting 5V.
Next, try resetting the GB40 by disconnecting it from the power source and then reconnecting it. This sometimes helps to reset the unit and fix any issues that may be causing it to only output 5V.
Jump-starts for less than six times
First, check the battery. Make sure that it is properly charged and that there are no loose connections.
If the battery seems to be fine, then the next step is to check the jump-start terminals. Make sure that they are clean and free of corrosion.
If the terminals are clean and the battery is charged, then the next step is to check the jumper cables. Make sure that they are the right size and that they are in good condition.
If the jumper cables are in good condition and the right size, then the next step is to check the engine. Make sure that there is no debris blocking the engine from starting.
If the engine is clear and the battery is charged, then the last step is to check the NOCO GB40 itself. Make sure that it is properly connected and that all of the settings are correct.
Lights keep running
First, check the batteries. If the batteries are low, recharge them or replace them with new ones. If the batteries are not the problem, then the issue may be with the light itself. Try cleaning the light with a soft cloth and see if that helps. If the light is still not working properly, you may need to replace it.
