BATTERY CHARGING TIMES

AUTOMATIC CHARGING MODE

When an automatic charge is performed, the charger switches to maintenance mode automatically after the battery is charged.

BAD BATTERY

If charging cannot be completed normally, the charger’s output is shut off, and the red Bad Battery LED will light. Do not continue attempting to charge this battery. Check the battery and replace it if necessary.

DESULFATION MODE

If the battery is left discharged for an extended period of time, it could become sulfated and not accept a normal charge. If the charger detects a sulfated battery, the charger will switch to a special mode of operation designed for such batteries. If successful, normal charging will resume after the battery is desulfated. Desulfation could take 8–10 hours. If desulfation fails, the red Bad Battery LED will light.

COMPLETION OF CHARGE

Charge completion is indicated by the green Charged LED. When lit, the charger has switched to the maintain mode of operation.

MAINTAIN MODE (FLOAT MODE MONITORING)

When the green Charged LED is lit, the charger has started maintenance mode. In this mode, the charger keeps the battery fully charged by delivering a small current when necessary. If the charger has to provide its maximum maintain current for a continuous 12-hour period, it will go into abort mode (see Bad Battery section). This is usually caused by a drain on the battery, or the battery could be bad. Make sure there are no loads on the battery. If there are, remove them. If there are none, have the battery checked or replaced.

MAINTAINING A BATTERY

The unit maintains both 6 and 12-volt batteries, keeping them at full charge. It is not recommended for industrial applications.

NOTE: The maintain mode technology allows you to safely charge and maintain a healthy battery for extended periods of time. However, problems with the battery, electrical problems in the vehicle, improper connections, or other unanticipated conditions could cause excessive current draws. As such, occasionally monitoring your battery and the charging process is recommended.

12. 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. Occasionally, cleaning the case of the charger with a soft cloth will keep the finish shiny and help prevent corrosion.
3. Coil the input and output cords neatly when storing the charger. This will help prevent accidental damage to the cords and charger.
4. Store the charger unplugged from the AC power outlet in an upright position.
