In the gasoline-only 2016 Outlander, you’ll find a standard 12-volt starting battery. In the Outlander PHEV (plug-in variant), the vehicle uses a much larger high‑voltage battery pack for its electric drive, separate from the 12V system.
Because Mitsubishi offered both a conventional gasoline model and a plug-in hybrid in 2016, battery specifications vary by model and market. This article outlines the typical sizes and how to confirm the exact specification for your vehicle.
Two battery systems in the 2016 Outlander
Below are the common configurations you’ll encounter on a 2016 Outlander, along with guidance on identifying the correct size for your specific car.
Gasoline Outlander: 12V starting battery
The gasoline version of the 2016 Outlander uses a conventional 12-volt lead-acid automotive battery to run the starter and accessories.
- Battery type: 12V lead-acid starting battery
- Common replacement group sizes: around Group 35 (some markets report 34R)
- Typical capacity: about 60 Ah
- Approximate cold-cranking amps (CCA): roughly 540–600 CCA
- Location: under the hood, mounted in a tray with clamps
When replacing, use the same group size and rating as the original, and verify the label on the battery for exact specifications for your VIN and market.
Outlander PHEV: high-voltage traction battery
The plug-in hybrid Outlander uses a separate high-voltage lithium‑ion battery pack that powers the electric motor and supports hybrid operation.
- High-voltage battery type: lithium‑ion
- Capacity: about 12 kWh (gross); usable capacity is slightly lower and varies by model year
- System voltage: approximately 400 volts
- Location: integrated under the floor of the vehicle, contributing to cabin and cargo space layout
- Maintenance: high-voltage packs require specialized service and are not user-serviceable like the 12V battery
Because the PHEV’s battery is part of the hybrid system, it’s not a like-for-like 12V battery replacement item. For repairs or replacements, rely on Mitsubishi's PHEV service guidelines and ensure any work complies with the high-voltage safety requirements.
How to verify the exact size for your vehicle
To confirm the precise battery specification for your 2016 Outlander, use the steps below. Since specs can vary by market and production date, checking the label on the existing battery or the official documentation is the most reliable approach.
- Inspect the existing battery label for group size (e.g., Group 35 or 34R) and capacity (Ah) for the 12V battery.
- Refer to the owner's manual or the Mitsubishi service booklet for your vehicle’s exact spec, noting your market and VIN.
- Check the under-hood stamping or battery tray area, which often shows the original part number and size.
- Consult a Mitsubishi dealer or qualified automotive technician with your VIN to confirm the recommended replacement.
Using the exact approved specification ensures proper fitment, electrical performance, and warranty compliance.
Summary
The 2016 Mitsubishi Outlander covers two distinct battery configurations: a conventional 12V lead-acid starting battery for the gasoline model (typically around Group 35, about 60 Ah) and a 12 kWh high-voltage lithium‑ion battery for the Outlander PHEV (around 400V). Always verify the precise size using the battery label, the owner's manual, or a Mitsubishi dealer to account for market and production variations. If you’re replacing either battery, ensure you match the correct type, size, and safety guidelines for your specific vehicle.
