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 SPI15 with Power Supply maintains 12 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.
