FREQUENTLY ASKED QUESTIONS
Q. Why does my jump starter take so long to charge on the dock?
A. Lower charging rate extends the battery life. The built-in charging circuit provides gentle charge with cell-
balancing for the internal Lithium Iron Phosphate (LiFePO
Q. Can the jump starter jump start vehicles at temperature lower than 0°C?
A. If the jump starter operates at temperatures below 0°C, its jump start rated performance will be reduced
but it will start vehicles with lower clamp output requirements.
Q. Why didn't my jump starter start my vehicle?
A. There could be a number of reasons why the jump starter did not start the vehicle.
Check the following:
•
Ensure you have firm clamp connection to battery posts and the battery posts are clean from grease
and dust build-up.
•
Ensure the jump starter is fully charged. Press the POWER
charge.
•
Ensure you have followed the correct operating procedure. Refer to JUMP STARTING INSTRUCTIONS.
•
Ensure the vehicle operates at 12V DC or 24V DC.
•
If the ambient temperature is low (<15˚C), the jump starter performance will be reduced. Repeat the
jump start routine 1–3 times as the battery performance will improve with each concurrent
start.
•
Ensure the vehicle being jump started does not require a clamp output of greater than 1000A for 12V
DC batteries and 850A for 24V DC batteries for IS3000 or 1500A for 12V DC batteries and 1000A for
24V DC batteries for IS5000 in order to jump start the vehicle.
•
If possible, connect clamps as close as possible to the starter motor without going through long cables.
Q. What is Peak Amps?
A. Peak amps is the maximum current the battery in the jump starter can produce.
Q. What is Clamp Power?
A. Clamp power is the maximum current available at the clamps.
