Replacing a Dodge Charger Battery is a straightforward process, but understanding a few key aspects ensures a smooth experience. This guide addresses common concerns about battery replacement in a 2018 Dodge Charger SXT Plus with a Pentastar V6 engine, specifically focusing on data loss, battery registration, and emission monitor resets.
Key Considerations for Dodge Charger Battery Replacement
While the battery replacement process in a Dodge Charger is similar to other vehicles, some unique aspects need attention. One common concern is potential data loss during the swap. Generally, disconnecting the battery will reset the radio presets, clock, and trip computer. However, critical vehicle data is stored in non-volatile memory and won’t be affected.
Battery registration is another frequently asked question. For newer Dodge Chargers, battery registration might be necessary to optimize charging performance and battery life. This process involves informing the vehicle’s computer about the new battery’s specifications. Consult your owner’s manual or a qualified technician to determine if battery registration is required for your specific model year.
A crucial factor to consider is the reset of the engine controller’s emission monitors after a battery disconnect. This reset isn’t a cause for concern unless a state inspection is imminent. After a battery replacement, the vehicle needs some driving time to complete emission monitor tests. If the inspection occurs before these tests are finished, the car might fail due to monitors being in a “not ready” state. It’s recommended to postpone the battery replacement until after the inspection or allow sufficient driving time afterward for the monitors to reset.
Performing the Battery Replacement
Utilizing a jump box connected to the jump posts under the hood provides continuous power to the vehicle during the battery swap, preventing the emission monitor reset. This is a valuable technique if an impending inspection is a concern. The jump box maintains power to the vehicle’s systems, allowing for a seamless battery replacement without triggering system resets.
Following standard battery replacement procedures and electrical safety protocols is crucial for a safe and successful process. Wear appropriate safety gear, ensure the ignition is off, and disconnect the negative terminal first, followed by the positive terminal. Install the new battery in reverse order, connecting the positive terminal first, then the negative terminal. After installation, double-check for secure connections and proper fit.
Conclusion
Replacing the battery in a 2018 Dodge Charger SXT Plus is relatively simple when following proper procedures and considering the potential impact on vehicle systems. By understanding the emission monitor reset process and utilizing a jump box if necessary, you can avoid potential inspection failures. Remember to consult your owner’s manual or a qualified technician for specific recommendations regarding battery registration. With careful preparation and execution, you can successfully replace your Dodge Charger’s battery and keep your vehicle running smoothly.
