Times are based on a 50% discharged battery and may change, depending on age and condition of battery.

AUTOMATIC CHARGING MODE

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

BATTERY CONNECTION INDICATOR

If the charger does not detect a properly connected battery, charging will not start and the digital display will show one of two messages. If the display shows CONNECT

CLAMPS, make sure the charger is connected to the battery and the connection points are clean and making a good connection. If the display shows WARNING CLAMPS

REVERSED, unplug the charger from the AC outlet, reverse the connections at the battery, and then plug the charger back in.

CHARGE COMPLETION AND MAINTAIN MODE (FLOAT MODE MONITORING)

Charge completion is indicated by the GREEN LED pulsing and the digital display showing FULLY CHARGED-AUTO MAINTAINING. This means that the charger has

stopped charging and has switched to the Maintain Mode of operation. NOTE: If the charger has to provide its maximum maintain current for a continuous 12 hour period,

it will go into Abort Mode (see Aborted Charge 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

This unit maintains 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 required.

ABORTED CHARGE

If charging cannot be completed normally, charging will abort. When charging aborts, the charger’s output is shut off, the GREEN LED will ash, and the display will show

CHARGE ABORTED-BAD BATTERY. To reset after an aborted charge, unplug the charger from the outlet, wait a few moments and plug it back in.

FAN: Your charger is equipped with a fan. It is normal for the fan to run while the charger is charging. Keep the area near the charger free of obstructions, to allow the fan

to operate efciently.

13. DISPLAY MESSAGES

SELECT BATTERY TYPE (no LED lit) – Waiting for user to select battery type. The charger will remember the battery type selected.

LITHIUM ION BATTERY-PRESS AGAIN FOR LEAD ACID (no LED lit) –Charging will begin for lithium-ion battery type. Press again to change to lead-acid battery type.

LEAD-ACID BATTERY-PRESS AGAIN FOR LITHIUM ION (no LED lit) –Charging will begin for lead-acid battery type. Press again to change to lithium-ion battery type.

CONNECT CLAMPS TO LITHIUM ION BATTERY (no LED lit) – Plugged into the AC outlet, and lithium-ion battery type is selected, without the clamps connected to a battery.

CONNECT CLAMPS TO LEAD-ACID BATTERY (no LED lit) – Plugged into the AC outlet, and lead-acid battery type is selected, without the clamps connected to a battery.

WARNING CLAMPS REVERSED (no LED lit) – Plugged into the AC outlet and the clamps are connected backwards to a battery.

ANALYZING LEAD-ACID BATTERY (or) ANALYZING LITHIUM BATTERY (green LED lit) – Plugged into the AC outlet, and when rst connected correctly to a battery.

CHARGING 12V – xx% (green LED lit) – Plugged into the AC outlet and correctly connected to a discharged 12V battery.

FULLY CHARGED-AUTO MAINTAINING (green LED pulsing) – Plugged into the AC outlet and correctly connected to a fully charged battery.

CHARGE ABORTED-BAD BATTERY (green LED ashing) – Circumstances that could cause an Abort situation during charging:

• The battery is severely sulfated or has a shorted cell and can’t reach a full charge.

• The battery is too large or there is a bank of batteries and it doesn’t reach full charge within a set time period.

Circumstances that could cause an Abort situation during maintain:

• The battery is severely sulfated or has a weak cell and will not hold a charge.

• There is a large draw on the battery and the charger has to supply its maximum maintain current for a 12 hour period to keep the battery at full charge.

BATTERY DISCONNECTED (no LED lit) – After charging has begun, the charger has lost its connection to the battery.

14. MAINTENANCE AND CARE

A minimal amount of care can keep your battery charger working properly for years.

• Clean the clamps each time you are nished charging. Wipe off any battery uid that may have come in contact with the clamps, to prevent corrosion.

• Occasionally cleaning the case of the charger with a soft cloth will keep the nish shiny and help prevent corrosion.

• Coil the input and output cords neatly when storing the charger. This will help prevent accidental damage to the cords and charger.

• Store the charger unplugged from the AC power outlet in an upright position.

• Store inside, in a cool, dry place. Do not store the clamps clipped together, on or around metal, or clipped to the cables.
