FREQUENTLY ASKED QUESTIONS
Q. How many jumpstarts can a fully charged IS1500 do?
A. 150 petrol/26 diesel jumpstarts with 20 sec RRT (vehicle without a battery) or 300 petrol/144
diesel emergency jumpstarts (with a flat vehicle battery**). With 40 seconds of RRT IS1500
will do an UNLIMITED* number of starts.
Q. Why does my jumpstarter take so long to charge?
A. Lower charging rate can lengthen the battery life. The built-in charging circuit provides gentle
and cell-balanced 2-stage charge for the internal lithium iron phosphate battery.
Q. Can IS1500 jumpstart vehicles at below zero temperature?
A. If IS1500 operates at temperatures below zero degrees, its jumpstart capacity will be reduced
but it will start vehicles with lower clamp output requirements.
Q. Why didn’t my jumpstarter start my vehicle?
A. There could be a number of reasons why the jumpstarter did not start your vehicle.
Check the following:
1. Ensure the jumpstarter is fully charged. Press the BATTERY STATUS button to check the
condition of the battery.
2. Ensure you have followed the correct operating procedure. Refer to page 6 (Vehicle
Jumpstarting Instructions)
3. Ensure the vehicle operates at 12V DC.
4. If the ambient temperature is low (<15
0
C), the jumpstarter capacity will be reduced.
Repeat the jumpstart routine 1–3 times as the battery performance will improve with
each jumpstart.
5. Ensure the vehicle being jumpstarted does not require a clamp output of greater than
550 Amps in order to jumpstart the vehicle.
Q. What is Peak Amps?
A. Peak amps is the maximum current the battery in the Jumpstarter can produce.
Q. What is Clamp Power?
A. Clamp power is the maximum current available at the clamps.
