How much is a Lexus RX hybrid battery?

Expect about $2,000 to $5,000 for a full RX hybrid battery replacement, with most installations landing in the $3,000 to $4,500 range. Costs vary by model year, battery type, and whether you use a new OEM pack or a refurbished unit.


What determines the price


The following factors shape the total cost of replacing a Lexus RX hybrid battery. Understanding them helps buyers compare quotes and avoid surprises during service.



  • Vehicle generation and model year (older RX 400h versus newer RX 450h/350h variants) and the corresponding battery design.

  • Battery chemistry and capacity (nickel-metal hydride vs. lithium-ion, when applicable), which affects replacement price and performance.

  • New OEM versus refurbished/remanufactured packs, including warranty terms.

  • Labor rates and regional pricing variations for diagnostics, removal, and installation.

  • Warranty status and potential dealership programs or incentives that can reduce out-of-pocket costs.


These elements collectively determine whether you pay toward the lower end of the spectrum or toward a higher, dealer-certified price.


Typical price ranges by replacement option


Prices differ depending on whether you isolate a new OEM pack or opt for a refurbished unit, along with labor charges.



  • New OEM battery pack (installation included): commonly around $3,000 to $5,000, depending on model year and location.

  • Refurbished/remanufactured battery pack: typically around $1,500 to $3,500, with installation bringing the total to roughly $2,500 to $4,500.

  • Labor and ancillary costs: usually a few hundred to over a thousand dollars, varying by shop and region.


In practice, the total outlay reflects the combination of pack choice, local labor rates, and the specific RX generation involved.


Generational snapshot: rough price bands


Here are broad ranges to give a sense of scale across major RX hybrid generations. Actual quotes depend on the exact vehicle, location, and warranties.



  • Older RX 400h (mid-2000s to early 2010s): refurbished around $1,000–$2,500; new around $2,500–$4,000; installed about $3,000–$5,500.

  • RX 450h (late 2000s to mid-2010s): refurbished around $1,500–$2,800; new around $3,000–$4,800; installed $3,500–$6,000+

  • Latest RX hybrids (2016–present, including RX 350h/450h): refurbished around $2,000–$3,500; new around $3,000–$5,000; installed $3,500–$6,500


These bands are designed to guide expectations; precise pricing requires diagnostic quotes from a dealer or trusted independent shop.


Warranty and cost-saving considerations


Warranty coverage can significantly affect out-of-pocket costs. In many markets, hybrid components carry substantial protection—often 8 years or 100,000 miles—and some states extend coverage further. If the battery failure falls within a valid warranty window, replacement or repair costs may be substantially reduced or covered.


Some owners also weigh the value of using a reputable refurbished pack with a solid warranty as a cost-efficient middle path between a brand-new OEM unit and a DIY or aftermarket alternative.


What to do if your RX shows hybrid-battery symptoms


If you notice reduced electric driving capability, warnings from the hybrid system, or diminishing fuel economy, schedule a diagnostic with a Lexus-certified technician. They can confirm battery health, test the hybrid system, and provide a formal replacement or remediation quote.


Summary


Replacing a Lexus RX hybrid battery is a significant, price-variable repair. A practical range for most owners is roughly $2,000 to $5,000 installed, with the exact figure depending on the RX generation, battery type, and whether you choose a new OEM pack or a refurbished unit. Gathering multiple quotes, verifying warranty terms, and weighing the vehicle’s remaining value will help you decide the most cost-effective path.
