The standard SAE (Society of Automotive Engineers).
A global standards development. An international society of over 83,000 engineers from 97 countries, which exchange know-how in the fields of automotive engineering, aerospace, engines, commercial vehicles, production, fuels and materials.
Batteries: Specifies that the battery at a temperature of –18°C will deliver a current equal to the Cold Cranking Amps for 30 seconds with the voltage staying above 7.2 volts (or 3.6 volts for a 6 volt battery).
Power Connectors/Adapters: The SAE connector is a physically self-mating connector (both male and female connections on each terminal). This connector is typically used for applying a maintenance charge to a battery. The polarity of the connector, when installed in a vehicle and attached to a battery, is always such that no short circuit will occur if the exposed terminal were to touch the chassis.
Lubricants/Oils: SAE establishes standards for motor oil viscosity, which helps determine how thick the oil is.
