Plug the charger power cord into an AC electrical wall outlet. Make sure to place the
charger on a dry, non-flammable surface.
7.
Select the battery type.
8.
When charging is complete, disconnect the AC cord from the supply mains, remove the
negative connector, and finally the positive connector.
BATTERY CONNECTION INDICATOR
If the charger does not detect a properly connected battery, charging will not start and the
digital display will show one of two messages. If the display shows
CONNECT CLAMPS
,
make sure the charger is connected to the battery and the connection points are clean and
making a good connection. If the display shows
WARNING-CLAMPS REVERSED
, unplug
the charger from 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,
use a manual charger to pre-charge the battery for five minutes, to get additional voltage
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 green LED will flash, and the display will show
CHARGE
ABORTED-BAD BATTERY
. To reset after an aborted charge, unplug the charger from the
AC outlet, wait a few moments and plug it back in.
COMPLETION OF CHARGE
Charge completion is indicated by the pulsing green LED and the digital display showing
FULLY CHARGED-AUTO MAINTAINING
. This indicates the charger has switched to the
Maintain Mode of operation.
MAINTAIN MODE (FLOAT-MODE MONITORING)
When the green 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 SPI3S maintains 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
This charger adjusts the charging time in order to charge the battery completely, efficiently
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 battery fits into the chart.
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.
