Questions & Answers
Does this work for a 2009 3500 series dodge diesel with dual batteries
Please contact NOCO Support directly on the NOCO website with a little more detail about your vehicle's batteries so that we may assist you.
Does it charge car batteries?
Yes, the GENIUS10 is compatible with 12V and 6V Lead Acid and AGM batteries, as well as 12V Lithium Ion and Lithium Iron Phosphate (LiFePO4) batteries.
Can you use on car batteries
Yes, the GENIUS10 is designed for charging and maintaining 6V and 12V car batteries.
Is this the correct product to trickle charge the 12v battery on a 2026 Toyota Rav 4
Yes
12 volt battery went dry; added distilled h2o; will "5" recharge?
Yes, the GENIUS5 is capable of charging 12V Flooded Batteries.
I have a 2024 mercedes sprinter with RV buildout. Can I simply connect this to the charging posts under the hood and keep it plugged in as a trickle charger.
NOCO GENIUS Chargers require a direct connection to the battery in order to detect the battery and begin charging it. As long as the charging posts under the hood connect directly to the battery and no other vehicle electronics, this would work.
My 2026 Chevy Colorado‘s battery is dead. How do I use this Genesis 10 to get the most and quickest response from my dead battery
The GENIUS chargers need to be able to detect a battery before they start charging that battery, and they are only able to detect a battery that has 1V or more on it. If the charger is connected to a battery that is depleted below 1V, the charger won't detect that battery, and thus won't start charging it. In this case, the charger will just stay in Standby, and if you press the MODE button, you will not be able to select a charge mode. Force Mode is a feature that lets you override that, it forces the charger to start charging a battery that is depleted below 1V even though the GENIUS charger can't detect the battery. To put the GENIUS10 into Force Mode you would just press and hold the MODE button down for about seven (7) seconds. After that, all of the Mode LEDs will illuminate and begin flashing. You can then toggle through the modes as you normally would and select the appropriate charge mode for your battery. The selected charge mode will then operate under Force Mode for five (5) minutes, this is characterized by the selected mode and the percentage LEDs (starting with 25%) flashing back and forth. Once the 5 minutes are up, the charger will then return to standard charging and the selected mode will stop flashing and just go solid.
This is a slow battery charger what you need is a jump starter unit which can help you jump start the vehicle immediately and not wait for the battery to recharge.
Does it include a terminal harness?
The GENIUS2 comes with NOCO GC001 Clamps w/ Integrated Eyelets. The eyelets are connected to the clamps and can be accessed by simply unscrewing the clamps from the eyelets. The eyelets can then be mounted directly to the battery terminals.
