Troubleshooting/FAQs
Q. What should I do if the Jump-N-Carry will not hold a charge?
A. After fully charging the battery (see “Recharging” section), apply a 100 amp load to
the unit for a period of 6 seconds, while monitoring the battery voltage. The battery
is good if the voltage is 9.5 Vdc or higher. If the voltage is lower than 9.5 VDC,
suspect a weak or bad battery, which will need to be replaced.
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.
Q. After jump starting, can I leave the unit hooked to the battery to recharge the
Jump-N-Carry while the engine is running?
A. No. Attempting to recharge the Jump-N-Carry by this method is not
recommended. Vehicle alternators output anywhere from 25-125 amps. This
charging rate greatly exceeds the recommended recharging rate for the
Jump-N-Carry. Charging by this method will result in overcharging the
Jump-N-Carry battery, and may void the product warranty.
Q. What accessories can be used in the optional 12 volt outlet?
A. Any accessory up to 12 amps can be powered by the Jump-N-Carry. This unit
is equipped with an automatic reset circuit breaker, should the current exceed
12 amps. At the same time, this limits any recharge current through the 12-volt
outlet to 12 amps. One can power almost any 12-volt tool or accessory (examples:
impact wrenches, fans, radios, cellular phones, navigation equipment, camcorders,
emergency lights, trolling motors, coolers, small refrigerators, etc.).
