Common questions about manuals, registration, and support for this brand.
A solid red Error LED typically indicates reverse polarity. This means the battery clamps are connected to the wrong terminals (positive to negative). Reverse the connections to correct this.
If your vehicle battery is below 2-3 volts, the unit may not detect it automatically. Press and hold the Manual Override button (often marked with an exclamation point) for 3 seconds until the LEDs flash. WARNING: This disables safety protections like spark-proof technology.
No, the internal lithium-ion battery is not user-replaceable. Attempting to disassemble the unit may cause damage or injury and will void the warranty.
A blinking red Error LED generally indicates that the cables are connected properly but the internal battery is too hot. Allow the unit to cool down in a cooler environment before trying again.
No, the NOCO BOOST is a jump starter, not a battery charger. It is designed to deliver a burst of power to start the engine, but it does not recharge the lead-acid battery. You should drive the vehicle or use a separate battery charger to replenish the vehicle battery after starting.
