7.
The CHARGED (green) LED will light when charging is complete and the charger has gone into
maintain mode.
Manual Charging
1. Connect the battery and AC power following the precautions listed in sections 5, 6 and 7.
2. Set the BATTERY TYPE to Ca/Ca, AGM/GEL or Desulfation.
3. Set the MODE to MANUAL CHARGE. (The TIME LED will start blinking.)
4. Use and to set the time (shown in minutes) you want the charger to charge the battery. Set to
"HLd" to run the charger without a time limit.
5. Set the CHARGE RATE to 4A, 20A or 70A. NOTE: Charge rate cannot be selected while using
Desulfation Mode.
6. Press when you are ready to start charging.
NOTE: Be sure to monitor the charging procedure and stop when the battery is charged. Failure to do
so may cause damage to your battery or may cause other personal property damage or personal
injury.
Charging
If the charger does not detect a properly connected battery, the CONNECTED (yellow/orange) LED
will not light until such a battery is detected. Charging will not begin while the CONNECTED LED is not
on. When charging begins, the CHARGING (yellow/orange) LED will light.
Battery Percent and Charge Time
This charger adjusts the charging time in order to charge the battery completely, efficiently and
safely. The microprocessor automatically performs the necessary functions.
Charge Rate – The charge rate is measured in amps. This charger provides charge rates of 4A, 20A
and 70A. The 4A rate is for charging smaller batteries, such as those used for motorcycles and garden
tractors. Such batteries should not be charged using the 20A or 70A rate. The 20A and 70A rates are
for charging larger batteries. In the 20A and 70A mode, the charger begins at a low-charge rate and
increases the charge rate if it is determined that the battery can accept the higher rate. All charging
modes will decrease the charge current as the battery approaches maximum charge.
Automatic Charging Mode When an automatic charge is performed, the charger switches to the
maintain mode automatically after the battery is charged. For a battery with a starting voltage under
1 volt, press and hold for five seconds to start Automatic Charging, or use manual mode to pre-
charge the battery for five minutes to get additional voltage into the battery for the charger to
analyze.
Aborted Charge If charging cannot be completed normally, charging will abort. When charging aborts,
the charger's output is shut off, the CHARGING (yellow/orange) LED will go out and the digital display
will show « Bad Bat ». The charger ignores all buttons except in that state. Press to reset after an
aborted charge.
Desulfation Mode
If the battery is left discharged for an extended period of time, it could become sulfated and not
accept normal charge. If you select , the charger will switch to a special mode of operation designed
for sulfated batteries. For the best performance, AUTOMATIC CHARGE Mode is recommended for
Desulfation Mode. If successful, the charger will fully desulfate and charge the battery, and then the
green LED will light. Desulfation could take up to 10 hours in AUTOMATIC CHARGE mode. If
desulfation fails, charging will abort and the charger will go into Abort Mode. If MANUAL CHARGE
mode is selected and the timer is set to between 10-120 minutes, desulfation will stop at the
specified time. If the timer is set to HOLD, the maximum time for desulfation will be 10 hours.
Completion of Charge Charge completion is indicated by the CHARGED (green) LED. When lit, the
charger has stopped charging and switched to the Maintain Mode of operation. If you are charging a
deep cycle battery, the CHARGED LED comes on when the battery is charged enough for normal use.
