A typical Infiniti battery replacement varies widely by battery type. A standard 12-volt auxiliary battery usually costs about $150–$350 installed, while the high‑voltage battery packs used in hybrids or electrified models often run from roughly $3,000 to $10,000 or more, including parts and labor. Prices depend on model, battery type, warranty, and where you buy.
Battery types in Infiniti vehicles
Infiniti currently uses two main categories of batteries across its lineup: a standard 12‑volt auxiliary battery and higher‑voltage packs for hybrids and electrified models. Each type has its own price range and considerations.
12-volt auxiliary battery
Before listing typical prices, it’s useful to know that the 12‑volt battery powers accessories and starts the engine in most Infiniti models. Replacement is common over the life of a vehicle, often every 3–5 years depending on climate and usage.
- Installed price range: typically $150–$350, depending on whether the battery is an OE (original equipment) equivalent or an aftermarket option and the installer’s labor rate.
- OE vs aftermarket: Infiniti-branded 12‑V replacements can be at the higher end of the range, while reputable aftermarket options may be slightly cheaper.
- Warranty considerations: most 12‑V batteries come with a limited warranty, commonly 1–3 years, with some shops offering extended coverage.
Budget generally falls within a few hundred dollars for a routine 12‑V swap, plus any disposal fees or core charges. Extreme climates or premium AGM designs can push costs toward the higher end.
High‑voltage traction/high‑voltage battery
The high‑voltage pack is used for hybrid propulsion and any electrified Infiniti models. Replacement costs vary dramatically by model, pack size, and whether you choose a new OEM pack, a remanufactured unit, or a salvage option.
- Parts‑only price range: roughly $2,500–$7,500 for a new OEM high‑voltage battery, depending on the model and pack specifications.
- Installed total cost: commonly $3,000–$10,000, with some models or circumstances pushing beyond $12,000 when labor and ancillary components are included.
- Warranty considerations: many Infiniti hybrids and electrified models offer an 8‑year/100,000‑mile (or similar) warranty on the high‑voltage battery in the US, though exact terms depend on model and purchase date.
Because high‑voltage packs are complex and expensive, owners often weigh OEM replacements against remanufactured or salvage options, always considering warranty and safety implications.
Cost ranges by model and option
Prices can differ by model year, region, and whether you’re swapping a worn-out 12‑V battery or a high‑voltage pack in a hybrid or upcoming Infiniti electric model. Dealers may charge a premium for original equipment parts, while independent shops might offer lower labor rates and aftermarket battery options. Always verify the exact part and coverage for your vehicle’s VIN.
Where to buy and how to save
To secure the best price and legitimate warranty coverage, compare quotes from multiple sources and understand what each price includes. The following options are commonly considered by Infiniti owners facing a battery replacement.
- Shop around for quotes from Infiniti dealerships, independent auto-electric specialists, and reputable online retailers for OEM and aftermarket 12‑V batteries.
- Ask about what’s included in the price: core charges, disposal fees, warranty duration, and whether installation is included.
- Consider remanufactured or refurbished high‑voltage packs only from trusted suppliers, and check warranty terms and compatibility with your VIN.
- Verify safety and eligibility: high‑voltage work requires certified technicians and proper safety protocols; ensure the shop follows HV safety standards.
- Investigate bundled services: some shops offer battery diagnostics and replacement as part of broader maintenance packages that can reduce overall cost.
Careful shopping, clear warranty terms, and professional installation can help manage the total cost of ownership when Infinity battery work is required.
Summary
For Infiniti owners, the price landscape splits into two main paths. A typical 12‑volt auxiliary battery replacement is a few hundred dollars (roughly $150–$350 installed). High‑voltage battery packs for hybrids and electrified models are far more expensive, commonly ranging from about $3,000 to $10,000 installed, with potential costs exceeding that for certain models or aftercare options. Always verify model-specific pricing, warranty coverage, and whether the quote includes labor, core charges, and disposal. When in doubt, consult your nearest Infiniti dealer or a qualified auto-electric shop to obtain an accurate, VIN‑specific quote.
