We understand the value of maintaining a healthy car battery, and it’s crucial to consider how accessory mode affects it. The accessory mode draws power from the battery without the engine running to recharge it, which can lead to significant battery drain over time.
Many drivers often wonder about the impact of using their car’s accessory mode on the vehicle’s battery life. Accessory mode, which is activated when the ignition is turned to the ‘ACC’ position, allows the use of electrical accessories such as the radio or charging ports while the engine is off.
While it’s safe to use this mode for short periods, extended use can potentially leave the battery with insufficient charge to start the engine. Regularly starting the car and allowing the engine to run for a while helps maintain the battery charge and avoids the unwanted scenario of a dead battery. 1 Will Accessory Mode Kill Battery?
Auxiliary batteries vary in size and specification dependent on the demands placed on it by the vehicle electrical system and can be used as a safety back-up to support the main battery when required or to provide voltage for specific vehicle systems all of the time.
The primary battery supplies power to the starter motor and maintains essential power to the Engine Management System (EMS) which is essential for engine starting. Primary and secondary battery voltages are monitored to ensure sufficient voltage is available for the next start event and charge can be supplied to the secondary battery when required.
Every car features an accessory system that’s connected to the circuits. The accessory circuits include power windows, radios, stereos, and others. The retained accessory power system helps these accessories to stay on even when the car ignition is turned off. The accessories can be active for more than 600 seconds after switching the ignition off.
