than a lower rated battery under the same conditions. A battery is
rated in ampere hours (AH), reserve capacity (RC) and cold crank-
ing amps (CCA). The lower the rating, the quicker the battery will
charge.
Charge Rate – The charge rate is measured in amps. This charger pro-
vides 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 the START/STOP
( ) button 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 can not be completed normally, charging will abort. When
charging aborts, the charger's output is shut off, the CHARGING (yellow)
LED will go out and the digital display will display . The charger ig-
nores all buttons except the START/STOP (

Desulfation Mode
If the battery is left discharge 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. Activation of the special desulfation mode is
indicated by the CHARGING (yellow) LED blinking. If successful, normal
charging will resume after the battery is desulfated. The CHARGING
(yellow) LED will then stop blinking and stay lit. Desulfation could take up
to 10 hours. If desulfation fails, charging will abort and the charger will go
into abort mode.
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 (green)
LED comes on when the battery is charged enough for normal use.
