Locating the battery in a 2016 Jeep Cherokee is essential for maintenance, troubleshooting electrical issues, or installing an automatic start/stop system. While the standard battery position follows the conventional design for most modern crossovers, the integration of the start/stop feature introduces specific considerations regarding the battery type and monitoring system. Understanding the exact location and the components involved ensures a safe and successful operation.
Standard Battery Location Under the Hood
For the majority of 2016 Jeep Cherokee models, the primary 12-volt battery is situated in the engine compartment. You will find it on the passenger side, secured within a bracket near the front fender well. This location provides a balance between protection from the elements and accessibility for standard maintenance procedures. The negative and positive terminals are typically oriented towards the firewall, allowing for connection to the vehicle's electrical harness and starter motor.
Start/Stop System and Enhanced Battery Requirements
The 2016 Cherokee's available start/stop system is designed to improve fuel efficiency by automatically shutting down the engine when the vehicle comes to a complete stop, such as at a traffic light. This process places significant stress on the battery, which must handle frequent deep discharges and rapid recharges. Consequently, Jeep specifies the use of an Absorbent Glass Mat (AGM) battery for these specific models. An AGM battery is required to withstand the demands of the start/stop function and is usually marked with specific labeling indicating its suitability.
Identifying an AGM Battery for Your Cherokee
Look for the "AGM" or "Absorbent Glass Mat" printed directly on the battery casing.
Check for labels indicating "Start/Stop" or "EFB" (Enhanced Flooded Battery), though AGM is the standard for this model year.
Verify the voltage specification, which is typically 12-volt, but confirm the Cold Cranking Amps (CCA) rating matches the original equipment manufacturer (OEM) specifications.
Battery Monitoring Sensor Location
A critical component of the start/stop system is the Battery Monitoring Sensor (BMS). This device measures the battery's temperature and state of charge to ensure the system manages the charging cycles correctly. On the 2016 Jeep Cherokee, this sensor is not located on the battery itself. Instead, it is clipped onto the battery cable, specifically on the positive cable that runs between the battery and the alternator. This placement allows the vehicle's computer to accurately assess the battery's condition in real-time.
Maintenance and Replacement Considerations
When replacing the battery in a 2016 Cherokee equipped with start/stop, it is not sufficient to install any standard 12-volt battery. Installing a conventional flooded lead-acid battery in this system can lead to premature failure and may trigger warning lights on the dashboard. The replacement must be an AGM battery that meets or exceeds the original specifications. Furthermore, the Battery Monitoring Sensor often needs to be transferred from the old battery to the new one, or a new sensor may be required to ensure the system recognizes the new component.
Safety and Professional Installation
Working with the battery and electrical system involves inherent risks, including the potential for short circuits or personal injury. It is crucial to disconnect the negative terminal first before beginning any work. Due to the complexity of the start/stop system and the requirement for a specific AGM battery, many owners find it beneficial to consult a certified technician or a Jeep dealer. Professionals possess the diagnostic tools to properly register the new battery with the vehicle's computer and verify that all electrical functions are operating correctly after the replacement.
