charging tips

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.

MAINTENANCE AND CARE

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.
