Low Voltage Batteries & Manual Override

The GBX155 is designed to jump start 12 volt lead acid batteries down to 3 volts. If your battery is below 3 volts, the Boost LED will be "Off". This is an indication that the GBX155 can not detect a battery. If you need to jump start a battery below 3 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.

Before use, please read and follow user guide for more important information on how to operate the unit and troubleshooting.
