Digital Display
The Digital Display gives a digital indication of voltage, % of charge or time. The display
will show the battery VOLTAGE when the charger is not charging a battery. When it
goes into charging mode, the display will automatically change to ON (to show charging
has started) and then show the percent-of-charge of the battery being charged and
either 6 or 12 (the voltage the charger determined the battery is). If you manually stop
the charging process (by pressing the CHARGE RATE button) before the battery is fully
charged the display will show OFF.
• Battery % – The digital display shows an estimated charge percentage of the battery
connected to the charger battery clips.
• Voltage – The digital display shows the voltage at the charger battery clips in DC volts.
NOTE: Once the charger has started charging the battery; if you press the Charge Rate
button once, the output current is shut off and the display with show OFF and then the
battery voltage. If you press the Charge Rate button again, the current will go back on at
the same setting it was when it was turned off. For example: The charger is charging a
battery at the slow charge rate setting. If you press the Charge Rate button, the output is
turned off. If you press the Charge Rate button again, the output will turn back on at the
slow charge rate setting.
9. OPERATING INSTRUCTIONS
WARNING
This battery charger must be properly assembled in accordance with the
assembly instructions before it is used.
Battery Information
This charger can be used with 6 and 12V batteries with rated capacities of 12 Ah to 111 Ah.
Charging
1. Ensure that all of the charger components are in place and in good working
condition, for example, the plastic boots on the battery clips.
2. Connect the battery following the precautions listed in sections 5 and 6.
3. Connect the AC power following the precautions listed in section 7.
4. Select the appropriate settings for your battery.
IMPORTANT
This charger does not have an ON/OFF switch. ON and OFF are controlled
by plugging in the charger to the AC wall outlet. The charger will not supply current to
the battery clips until a battery is properly connected. The clips will not spark if touched
together.
Startup Defaults: When rst turned on, the charger will default to the following
startup settings:
• Battery Type: Standard
• Charge Rate: OFF (No charge rate selected)
After 10 minutes, if no charge rate is selected, the charger will automatically start
charging at the following defaults:
• Charge Current: The lowest charge rate setting available, 3 amps.
• Charge Voltage: The lowest charge rate voltage available, usually 14.7 volts (Gel
Cell), if not, then 15.4 volts (AGM), otherwise it will be 16.0 volts (Standard battery).
Battery Connection Indicator
If the charger does not detect a properly connected battery, the CONNECTED LED
will not light. Charging will not begin if the CONNECTED LED is not on.
Automatic Charging Mode
When a charge rate is selected, the charger is set to perform an automatic charge.
When an automatic charge is performed, the charger switches to the maintain mode
automatically after the battery is charged.
Aborted Charge
If charging cannot be completed normally, charging will abort. When charging aborts,
the charger’s output is shut off, all of the LEDs are turned off and the digital display
will show an error code (see Troubleshooting for a list of error codes). In that state, the
charger ignores all buttons. To reset after an aborted charge, unplug the charger.
