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.

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 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.Temperatureabove70˚Fdecreaseamperageoutput.Theideal

storageenvironmentisroomtemperature,or68˚F.
