How much does it cost to replace Lexus RX hybrid battery?
Typically, replacing a Lexus RX hybrid battery costs roughly $2,000 to $6,000, depending on model year, battery type, and labor.
The Lexus RX line has spanned several generations with different battery chemistries and pack sizes. Whether you opt for a brand-new OEM pack, a rebuilt unit, or a salvage battery, price tags vary widely and so do installation times and warranty options. This report outlines current pricing realities, how different options compare, and what buyers can expect in 2025.
What drives the price
Several factors influence the final bill, including the generation of the RX, the battery chemistry, the availability of packs, and who performs the replacement.
Cost options and typical ranges
Below are the main replacement routes and what they typically cost once installed. Prices vary by region and dealership or shop, so use these as ballpark figures.
- New OEM battery pack (factory replacement): Installed price commonly ranges from about $3,000 to $6,000, with higher-end trims or late-model packs at the top of the range. This option often carries the strongest warranty.
- Remanufactured/refurbished battery pack: Usually $1,800 to $4,000 for the part, with total installed costs around $2,500 to $5,000 depending on labor and warranty.
- Used or salvage battery pack: Part prices can be roughly $600 to $2,000, with total installed costs typically $1,800 to $3,500. Longevity and warranty are uncertain.
- Modular or service-center reconditioning: Some shops offer module-level replacements or reconditioning that may reduce cost to roughly $1,500 to $3,500 for parts plus labor.
Prices reflect typical market conditions and may differ in your area. Dealer-installed packs often carry longer warranties, but at higher upfront cost.
Warranty considerations
In the United States, hybrid battery warranties commonly cover eight years or 100,000 miles for the hybrid system, with variations by state and model. Some states have extended or different emissions-related warranties. Always confirm the exact terms with the dealer or installer for your VIN and location.
Cost by RX generation
Early RX hybrids (roughly 2005–2010, including RX 400h)
Battery packs from this era are typically NiMH and generally cheaper to replace than newer chemistries, with installed costs often in the $2,500 to $4,800 range, depending on condition and availability.
Second-generation hybrids (2010–2015, RX 450h)
Costs tend to be similar to early models, but parts availability and labor rates can push the total toward the upper end of the $2,500 to $5,000 range for a new or refurbished pack.
Recent models (2016–present, including RX 350h/ RX 450h and RX 500h)
Newer RX hybrids use larger or more complex packs; replacement tends to start around $3,000 and can reach $6,000 or more for OEM packs, with labor bringing totals to roughly $3,500–$6,500 depending on the configuration and installer.
Where to shop and how to save
To manage costs, buyers should explore multiple sources and weigh warranty vs price. The following options are common.
- Dealerships (Lexus dealers) offering OEM packs and service, often with robust warranties.
- Independent hybrid-specialist repair shops with certified technicians and updated tooling.
- Rebuilt or refurbished battery suppliers that include some warranty and post-install support.
- Salvage yards or online marketplaces offering used packs, typically with limited or no warranty.
Always verify compatibility for your exact RX model year and confirm the warranty terms before purchasing or scheduling service. If possible, obtain a written quote that breaks out the part and labor separately.
Summary
Replacing a Lexus RX hybrid battery is a potentially costly maintenance item, but several paths exist to match budget and risk tolerance. OEM new packs offer the longest life and strongest warranties but at a premium, while refurbished or salvage options can lower upfront costs at the risk of shorter or uncertain life. Check your warranty, compare multiple quotes, and choose a vetted installer to maximize reliability and value in 2025.
