A replacement cost varies by battery type: typically about $150–$350 for the standard 12‑volt battery on non-hybrid Outlanders, while the high‑voltage traction battery in the Outlander PHEV can run into the thousands. Labor costs depend on the shop and region.
The article below covers the two main battery types you might be dealing with, how prices break down, and what to consider when replacing, including warranty and options for refurbished packs.
12-volt battery replacement (non-hybrid Outlander)
This section covers the standard 12‑volt battery used to start the engine and power accessories in traditional (non-hybrid) Outlander models. The price you pay hinges on the battery type, brand, and where you have it installed.
What affects price
Cost varies by battery type (lead-acid vs. AGM), brand, warranty, and whether you buy at a dealer or an independent shop. Installation charges, disposal fees, and any required accessories can also influence the total.
Typical options and their prices are shown below.
- Budget lead-acid 12V battery: about $100–$150 for the part; installation adds roughly $50–$80; total roughly $150–$230.
- AGM 12V battery: about $150–$250 for the part; installation $50–$100; total roughly $200–$350.
- Dealer or premium aftermarket 12V battery: about $200–$350 for the part; installation $60–$120; total around $260–$470.
In most cases, plan for approximately $150–$350 total for a standard 12‑volt Outlander battery, with higher-end options leaning toward the upper end of that range depending on labor rates and warranty.
Warranty and service considerations
Most 12‑volt replacements carry at least a year or more of warranty through the manufacturer or retailer. If your vehicle is under an extended warranty or a Mitsubishi program, some or all of the replacement might be covered. Always ask for a written estimate that itemizes the battery and labor, and confirm whether any diagnostic fees are included.
High-voltage battery replacement (Outlander PHEV)
The Outlander PHEV uses a high‑voltage traction battery to power the electric drive. Replacing this pack is a much larger and more specialized job than a standard 12V battery change, often routed through a dealership or a certified hybrid/electric vehicle shop. Prices vary widely by year, pack condition, and whether the new pack is OEM or refurbished.
HV battery replacement options
Below are common pathways and their typical cost ranges, including installation.
- New OEM high-voltage battery pack: about $5,000–$8,000 for the part; installation often $1,000–$1,200; total roughly $6,000–$9,200.
- Remanufactured/refurbished HV pack: about $3,000–$5,000 for the part; installation $1,000–$1,200; total around $4,000–$6,200.
- Battery replacement via reconditioning or select cell/pack services: about $2,000–$4,000 for the part; installation $1,000–$1,200; total roughly $3,000–$5,200.
Notes: Availability of refurbished or reconditioned packs can depend on model year and regional suppliers. The high‑voltage system requires specialized tools and safety procedures, so expect to work with a dealer or qualified hybrid technician. Warranties for HV packs vary, and some programs may offer extended coverage or replacement incentives.
Warranty and service considerations
HV battery warranties are typically long, reflecting the importance and cost of the component. Check the specifics with the dealer, including what triggers warranty coverage (age, mileage, fault codes) and whether a replacement under warranty is process-driven (depot repair vs. on-site). Extended warranties or recall-related programs may apply in some regions.
Summary
Key takeaways: If you own a traditional Mitsubishi Outlander, you’ll likely pay in the low to mid hundreds for a new 12‑volt battery, with some variation by brand and labor. For the plug‑in Outlander PHEV, the high‑voltage battery replacement is far more expensive, typically spanning several thousand dollars to replace with a new pack, or somewhat less if a refurbished or reconditioned pack is available. Always obtain a written estimate, verify warranty coverage, and consider the aging of the current battery pack when deciding whether to repair or replace.
