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. Do not continue attempting to charge this battery. Check the
battery and replace, if necessary.
CHARGE COMPLETION AND MAINTAIN MODE (FLOAT MODE MONITORING)
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. 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 SPI1024 maintains 24 volt batteries, keeping them at full charge. It is not recommended
for industrial applications.
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.
FAN
Your charger is equipped with a fan. It is normal for the fan to run while the charger is charging.
Keep the area near the charger free of obstructions, to allow the fan to operate efficiently.

CONNECT CLAMPS (No LED lit) – Plugged into the AC outlet without the clamps
connected to a battery.
WARNING-CLAMPS REVERSED (No LED lit) – Plugged into the AC outlet and the
clamps are connected backwards to a battery.
ANALYZING BATTERY (Green LED lit) – Plugged into the AC outlet, and when first
correctly connected to battery.
CHARGING – xx% (Green LED lit) – Plugged into the AC outlet and correctly connected to
a discharged battery.
FULLY CHARGED-AUTO MAINTAINING (Green LED pulsing) – Plugged into the AC
outlet and correctly connected to a fully charged battery.
CHARGE ABORTED-BAD BATTERY (Green LED flashing) –
Circumstances that could cause an Abort situation during charging:
• The battery is severely sulfated or has a shorted cell and can't reach a full charge.
• The battery is too large or there is a bank of batteries and it doesn't reach full charge within
a set time period.
Circumstances that could cause an Abort situation during maintain:
• The battery is severely sulfated or has a weak cell and will not hold a charge.
• There is a large draw on the battery and the charger has to supply its maximum maintain
current for a 12 hour period to keep the battery at full charge.
BATTERY DISCONNECTED (No LED lit) – Clamps were unplugged during charging.
