Connecting to an External Battery
26
To connect the Duracell® Powerpack to an external 
battery using the jump-start cables:
1. Ensure that the jump-start power switch is 
OFF.
2. Connect the red positive (+) clamp of the cables to the 
red positive (+) terminal of the external battery.
3. Connect the black negative (–) clamp of the cables to the 
black negative (–) terminal of the external battery.
If the Red Jumpstart Connection LED illuminates and the 
alarm sounds, then reverse polarity has been detected. 
Correct polarity must be established before proceeding. 
Disconnect the jump-start clamps from the battery and 
redo steps 2 and 3 in this procedure.
If no alarm sounds, and the Green Jumpstart Connection 
LED is illuminated, then proceed to the next step.
4. Switch 
ON the jump-start power switch.
