NOCO Genius Boosts are 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 Boost 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 (FROM 400-4000 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 battery clamps are connected to the correct polarity battery terminals and the X-Connect Clamps are connected to Boost. 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.
CAUTION: POWER THE BOOST JUMP STARTER “OFF” BEFORE DISCONNECTING THE BATTERY CLAMPS. THIS WILL ENSURE YOUR SAFETY. REMEMBER BOTH THE SPARK PROOF AND REVERSE POLARITY PROTECTION FEATURES ARE DISABLED IN MANUAL OVERRIDE.
