CHARGING TIMES
The Charger will automatically adjust the charge rate as the battery charges and stops
charging when the battery is fully charged. If you require some estimate of the time it
takes to charge a battery refer to the chart below.

The times shown in the chart above are approximate and refer to an average auto-
motive battery. For smaller batteries, the charge time should be adjusted using the for-
mula shown below and adding 1 hour to the time calculated. To estimate charging
time for a discharged battery, divide the amp hour (AH) rating of the battery by the
charge rate selected. This is the number of hours required to recharge the battery. For
example, a 50 Ah (12 volt) battery is discharged (10 volts).
Question: How long should it be charged at the 6 Amp rate?
Divide the 50 Ah by 6.
Answer:
Approximately 8 hours. Always round up charge time by 10% to ensure full
charge. In most cases, battery charge times will vary depending on age and condi-
tion of battery. Smaller batteries should be charged at the lower rate (2 Amps) and
add an extra hour to charge time.
NOTE
: Deep cycle batteries may need longer charging time. It is recommended to
repeat the charging cycle a second time beginning with the 2 Amp rate.
CARE AND MAINTENANCE
With minimal maintenance, the Jump ‘n Charge system will provide years of depend-
able service.
•
After each use, clean the battery charger clamps - be sure to remove any battery
fluid that will cause corrosion of the copper clamps.
•
Clean the outside case of the charger with a soft cloth and, if necessary, mild soap
solution.
•
Do not use charger if cords or clamps have been damaged in any way - call
Vector Technical Support Department toll-free: (866) 584-5504 for replacement
cords/clamps.
TROUBLESHOOTING
NOTE
: Charger will NOT operate on batteries below 4.0 volts. If a 12 volt battery is
below 4.0 volts, it is probably shorted, open or sulfated. Replace the battery.
The following conditions may light the FAULT LED:
•
Charging too fast - Decrease Charge Rate - Press 2/4/6 Amp pushbutton to
select lower rate.
