Read this entire manual before using your charger. The tips below serve only as a guide 

for specific situations.
If your vehicle won’t start: You don’t need 

to fully charge a battery to start your ve-

hicle. If the charger won’t start your vehicle 

using the 75A START rate, try charging the 

battery using the 12A 

  30A rate for 10 

or 15 minutes. That should charge the bat-

tery enough to allow the 75A START rate 

to start the vehicle. If the vehicle will then 

be operated continuously for an extended 

period (such as a long drive), the vehicle 

could charge the battery back to normal 

during that period. If the vehicle will only 

be operated for a short period (short drive), 

the battery might need to be charged again 

before it could start the vehicle again.

Reviving your battery: If you only wish 

to charge your battery enough to operate 

your vehicle, you don’t need to wait for the 

entire charging process to be completed. 

When  the  charger  displays  a  battery  % 

of 77 or more (see page 13), the battery 

has usually been charged enough for the 

vehicle to start and operate normally.
Completing  an  interrupted  charge:  If 

the charging process has been interrupted 

and restarted after the charger displays a 

battery % of 85 or more, the charger could 

go straight to Maintain Mode (see page 8). 

However, if the original charge was started 

using 12A 

  30A, the charge can often 

be completed using the 2A rate.

A minimal amount of care can keep your battery charger working properly for years.
1.  Clean the clamps each time you are finished charging. Wipe off any battery fluid 

that may have come in contact with the clamps to prevent corrosion.

2.  Coil the input and output cords neatly when storing the charger. This will help pre-

vent accidental damage to the cords and charger.

3.  Occasional cleaning of the case of the charger with a soft cloth will keep the finish 

shiny.
