An Intelligent Access car battery is a specialized battery designed for use in vehicles equipped with Ford’s Intelligent Access system, which allows keyless entry and push-button start. This battery is specifically engineered to provide the necessary power to support the electronic systems and features of the vehicle, including the Intelligent Access system.
Technical Specifications of Intelligent Access Car Battery
The technical specifications of an Intelligent Access car battery can vary depending on the make and model of the vehicle. However, in general, these batteries are designed to provide a higher level of power and performance than a standard car battery. Some key technical specifications include:
-
Cold Cranking Amps (CCA): Intelligent Access car batteries typically have a higher CCA rating, which measures the battery’s ability to start the engine in cold temperatures. For example, a standard car battery may have a CCA rating of around 500-600 amps, while an Intelligent Access battery may have a CCA rating of 700-800 amps or higher.
-
Capacity: Intelligent Access car batteries often have a higher capacity, measured in amp-hours (Ah), to support the increased power demands of the vehicle’s electronic systems. A standard car battery may have a capacity of 40-60 Ah, while an Intelligent Access battery may have a capacity of 60-80 Ah or more.
-
Vibration Resistance: Intelligent Access car batteries are designed to be more resistant to vibration and other forms of damage, which can be important in vehicles that experience more frequent or intense vibrations, such as trucks or off-road vehicles.
-
Lifespan: Intelligent Access car batteries are engineered to have a longer lifespan compared to standard car batteries, often lasting 4-6 years or more with proper maintenance and care.
Battery Monitoring and Charging
One important feature of an Intelligent Access car battery is its ability to monitor the battery’s state of charge and temperature. This is done using a current sensor, which measures the amount of current flowing in and out of the battery, and a temperature sensor, which measures the battery’s temperature. This information is then transmitted to the vehicle’s BCM (Body Control Module) through the Lin Network, allowing the vehicle to adjust its charging rates based on the battery’s condition.
When charging an Intelligent Access car battery, it is important to connect the positive clamp to the positive terminal and the negative clamp to a body ground, such as the engine block. This is because the current sensor in the battery monitoring system measures the current as it flows past the sensor, and connecting the negative clamp directly to the battery terminal can interfere with this measurement.
Jump-Starting an Intelligent Access Vehicle
When jump-starting a vehicle with an Intelligent Access battery, it is important to connect the jumper cables to the battery terminals on the other side of the current sensor. This allows the BCM to recognize that amperage is being added back into the battery, which is necessary for the vehicle’s systems to function properly.
Replacing an Intelligent Access Car Battery
Replacing an Intelligent Access car battery is similar to replacing a standard car battery, but there are a few important things to keep in mind:
-
Battery Compatibility: It is crucial to use a battery that is compatible with the vehicle’s Intelligent Access system. This may mean using a battery with a higher CCA rating or one that is specifically designed for use with the Intelligent Access system.
-
Battery Monitoring System: When replacing the battery, it is important to ensure that the battery monitoring system is properly connected and functioning. This may involve resetting or recalibrating the system to ensure that it can accurately monitor the new battery’s state of charge and temperature.
-
Battery Disposal: When disposing of an old Intelligent Access car battery, it is important to follow local regulations and guidelines for the proper disposal of automotive batteries, which may contain hazardous materials.
By understanding the technical specifications, monitoring and charging requirements, and proper replacement procedures for Intelligent Access car batteries, DIY enthusiasts can ensure that their vehicles’ keyless entry and push-button start systems continue to function reliably and efficiently.
