BATTERY CONNECTION INDICATOR
If the charger does not detect a properly connected battery, charging will not start and the
red the AC outlet, reverse the connections at
the battery, and then plug the charger back in.
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,
into the battery.
ABORTED CHARGE
If charging cannot be completed normally, charging will abort. When charging aborts, the
charger's output is shut off, the yellow/orange CHARGING
aborted charge, unplug the charger from the AC outlet, wait a few moments and plug it back in.
DESULFATION MODE
If the battery is left discharged 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. If successful, normal charging
will resume after the battery is desulfated. Desulfation could take up to 8 hours. If desulfation
fails, charging will abort, and the yellow/orange CHARGING
COMPLETION OF CHARGE
Charge completion is indicated by the green CHARGED LED. When pulsing, the
charger has switched to the Maintain Mode of operation.
MAINTAIN MODE (FLOAT-MODE MONITORING)
When the green CHARGED LED is pulsing, the charger has started Maintain Mode.
In this mode, the charger keeps the battery fully charged by delivering a small current
when necessary. 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
The SPI2 maintains 6 and 12 volt batteries, keeping them at full charge.
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 recommended.
13. CALCULATING CHARGE TIME
BATTERY PERCENT AND CHARGE TIME
and safely. The microprocessor automatically performs the necessary functions. This section
includes guidelines that can be used to estimate charging times. Use the following table to
determine the time it will take to bring a battery to full charge. First, identify where your
CCA = Cold Cranking Amps Ah = Amp Hour
Find your battery's rating on the following chart, and note the charge time given for each
charger setting. The times given are for batteries with a 50% charge prior to recharging.
Add more time for severely discharged batteries.
