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 . The charger ignores all buttons except
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
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.
Maintain Mode
When the CHARGED (green) LED is lit, the charger has started Maintain Mode. In this
mode, the charger keeps the battery fully charged by delivering a small current when
necessary. The voltage is maintained at 13.2V.
