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 SPI3 CANBUS 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
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.

PROGRAM 1 (NORMAL)
SELECT BATTERY TYPE (No LED lit) – Waiting for user to select battery type.
LEAD-ACID BATTERY-PRESS AGAIN FOR LITHIUM ION (No LED lit) – Charging will
begin for lead-acid battery type. Press again to change to lithium ion battery type.
LITHIUM ION BATTERY-PRESS AGAIN FOR LEAD ACID (No LED lit) –Charging will
begin for lithium-ion battery type. Press again to change to lead-acid battery type.
CONNECT CLAMPS TO LITHIUM ION BATTERY (No LED lit) – Plugged into the AC
outlet, and lithium-ion battery type is selected, without the clamps connected to a battery.
CONNECT CLAMPS TO LEAD-ACID BATTERY (No LED lit) – Plugged into the AC outlet,
and lead-acid battery type is selected, 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 12V battery.
