KNOW YOUR CHARGER

Read this entire manual before using your charger. The items below are additional features of your charger.

operate efficiently.

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 prevent 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 and help prevent corrosion.

4.Store the battery charger in a clean and dry location.

BATTERY CHARGE TIME

This charger adjusts the charging time in order to charge the battery com- pletely, efficiently and safely. The mi- croprocessor automatically makes the necessary decisions. However, this section includes guidelines that can be used to estimate charging times.

The duration of the charging process depends on three factors:

1.Battery State – If a battery has only been slightly discharged, it can be charged in less than a few hours. The same battery could take up to 10

hours if very weak.

2. Battery rating – A higher rated battery will take longer to charge than a lower rated battery under the same conditions. A battery is rated in ampere-hours (AH), reserve capacity (RC) and cold cranking amps (CCA). The lower the rating the faster the battery will be charged.

3. Charge rate – The charge rate is measured in amps. This charger provides charge rates of 2A, 6A and 10A. The 2A rate is for charging smaller batteries such as those used

for motorcycles and garden tractors. Such batteries should not be charged using the 6A or 10A rates. The 6A and 10A rates are for charging larger batteries. The charger charges at the selected charge rate and eventually reduces the charge rate in a con- trolled manner. After the charging process has started, the charger led’s can be used to determine charging progress.

There are some important facts to keep in mind when charging a battery.

When the led below the charged led is lit, the battery has been charged enough to start most vehicles and has already been charged as much as by many other battery chargers.

The more a battery is discharged, the faster it absorbs charge from a charger. That means that the battery charge increases faster at the beginning of the charging process than at the end. In other words, it takes longer for the battery to absorb the last few percent of charge than the first several percent.
