When recharging, the charge level of the internal battery is indicated by the Charge
LEDs. The LEDs will slowly pulse 'On' and 'O' and become solid until all four Charge
LEDs are on. When the battery is fully charged, the Green 100% LED will be solid, and
the 25%, 50% and 75% Charge LEDs will turn "O". From time to time, the Green
100% LED will pulse indicating maintenance charging is occuring.
How To Use
Step 1: Charge the GB251.
The GB251 comes partially charged out of the box and needs to be fully charged
prior to use. Connect the GB251 using the included 12V DC car charger or XGC4 wall
charger to the 12V IN port. The time to recharge a GB251 will dier based on the
discharge level and the power source used. Actual results may vary due to battery
conditions and level of discharge.

Step 2: Connect to the Battery.
Carefully read and understand the vehicle owner's manual on specific precautions and recommended methods for jump starting the
vehicle. Make sure to determine the voltage and chemistry of the battery by referring to your battery owner's manual prior to using this
product. The GB251 is for jump starting 24-volt lead-acid battery systems only. Before connecting to the battery, verify that you have
a 24-volt lead-acid battery system. The GB251 is not suitable for any other type of battery. Identify the correct polarity of the battery
terminals on the battery. The positive battery terminal is typically marked by these letters or symbol (POS,P,+). The negative battery
terminal is typically marked by these letters or symbol (NEG,N,-). Do not make any connections to the carburetor, fuel lines, or thin, sheet
metal parts. The below instructions are for a negative ground system (most common). If your vehicle is a positive ground system (very
uncommon), consult the vehicle's manual for proper jump starting instructions.
1.) Connect the positive (red) battery clamp to the positive (POS,P,+) battery terminal and the negative (black) battery clamp to the
negative (NEG,N,-) battery terminal or vehicle chassis.
