If the SFI battery voltage is below which value will charging not occur and maintenance action is required?

If the SFI battery voltage is below which value will charging not occur and maintenance action is required?

• A. 12 volts
• B. 20 volts
• C. 18 volts
• D. 19 volts

Answer: (C)

Charging is controlled by a voltage threshold on the SFI battery. The charging circuit will not engage unless the battery voltage is at least eighteen volts. If the SFI battery falls below that threshold, charging is inhibited and maintenance action is required because such a low reading typically indicates a severely discharged or faulty battery (or bad connections). Therefore, eighteen volts is the value below which charging won’t occur, and service should be performed to address the condition.
