The 12-volt battery in most INFINITI QX50 models is located in the engine compartment on the passenger side, under a protective cover. It is not in the trunk or beneath the rear seats.
This article explains exactly where to find the battery, how to identify its location in the engine bay, and what to know if you need to service or replace it. It covers model-year variations and practical safety tips for handling the battery.
Battery placement in the engine bay
In recent QX50 models, the 12-volt battery sits in the engine bay on the passenger side, beneath a molded plastic cover near the strut tower. It is a conventional lead-acid battery, separate from the vehicle's high-voltage system.
Details below help you locate it quickly and understand what you might see under the hood.
- Location: engine compartment, passenger side, toward the front, under a protective plastic cover.
- Orientation: standard mounting with terminals facing outward for easy access.
- Accessibility: typically reachable from the engine bay without removing major components; some trims may have auxiliary covers.
With the battery located, it's prudent to inspect the terminals for corrosion, ensure the cover is fully seated, and consult the owner's manual for service intervals.
Jump-starting or replacing the battery
For safety, avoid contact with the battery terminals and disconnect the negative terminal first when jump-starting or replacing the battery. Use the correct replacement specification as outlined in the manual. If you’re unsure, seek professional assistance.
Model-year variations are rare but possible; always verify by checking the labeling on the battery or the owner's manual for your exact QX50 year and trim.
