Performance and Temperature
Performance of your
Jump-N-Carry
will depend upon several factors:
• A good, solid connection between the
Jump-N-Carry
clamps and the battery
and ground connections are a must. Moving the clamps back and forth while
connecting to the battery will help create a better connection.
• Clean connections between your vehicle or equipment battery and its terminals
are very important. For an optimal connection, corrosion (soft grayish-white build-
up) on battery terminals must be removed. With the ignition turned off, disconnect
the battery cables and clean the terminals and battery posts with a baking soda
solution.
• All batteries are affected by temperature changes, and the small, lightweight
battery in the
Jump-N-Carry
is more sensitive to storage temperature than a
standard automotive battery. Temperatures below 70ºF decrease amperage output.
The ideal storage environment is room temperature, or 68ºF.
Troubleshooting/FAQs
Q. What should I do if the
Jump-N-Carry
will not hold a charge?
A. Load test the battery. After fully charging the battery (see “Recharging” section),
apply a 100 amp load (through the clamps) to the unit for a period of 6 seconds,
while monitoring the battery voltage. The battery is good if the voltage at the end of
the load is 9.5 Vdc or higher.
Q. What is the ideal use for the
Jump-N-Carry
?
A. The
Jump-N-Carry
performs strongly when a vehicle’s battery needs an extra
boost because a light or radio was left on, or when a vehicle has been sitting for
a long period of time. The
Jump-N-Carry
will start vehicles without any other
batteries present, but the primary use is for an extra boost.
Q. Will the
Jump-N-Carry
start every vehicle?
A. No. In addition to a dead battery, a car may have other mechanical problems that
would prevent the
Jump-N-Carry
from starting the vehicle.
Q. How often should I recharge the
Jump-N-Carry
?
A. To maximize battery life, charging after every use is recommended. The
Jump-N-Carry
should not be left in a discharged state. The battery in the
Jump-N-Carry
has no memory problems and should not be treated as a
rechargeable tool (cordless drills, camcorders, etc.).
Q. How many jump starts can I get from the
Jump-N-Carry
before recharging?
A. A large number of factors affect this answer, including the following: the length of
time for each jump start, the charge level of the original battery, the length of time
between jump starts, the temperature of the vehicles being jump started (winter
cold makes for difficult starting), the size of the engines (4-cycl, 6-cycl, 8-cycl, etc.),
the mechanical condition of the engine and starter, and more. These factors must
all be weighed on an individual basis before an accurate answer can be given. It’s
feasible to get 10-30 starts (individual’s results will differ) from a single charge, but
this violates the rule of immediate charging after every use.
