A replacement battery for a BMW 335i typically costs between $200 and $500 for the battery itself, with installation bringing the total to about $300 to $800 depending on the battery type and where you shop.
The 335i often relies on an AGM (absorbed glass mat) battery, especially on models with Start-Stop technology. Prices vary by OEM versus aftermarket options, battery capacity (for example, 90Ah versus 105Ah), and whether the vehicle requires battery registration or coding after installation. Exact costs depend on your model year, regional pricing, and your choice of parts and service provider.
Factors that affect price
Several elements influence the final bill for a 335i battery, including the battery type (OEM vs aftermarket), capacity (Ah and CCA ratings), whether Start-Stop is present, regional labor rates, and whether a coding or registration step is needed for the vehicle’s battery management system.
Typical options and price ranges
Here are common battery choices you’ll encounter, with approximate price ranges for the battery itself. Note that installation and any required battery registration are extra.
- OEM BMW AGM battery (90Ah; commonly used on Start-Stop models) – typically $350–$600 at a dealership; $200–$350 from many independent shops or online retailers.
- Aftermarket AGM batteries from reputable brands (Bosch, VARTA, Yuasa, Interstate) – typically $180–$350, depending on capacity and where bought.
- Higher-capacity or premium AGM batteries (105Ah or reinforced cold-cranking amps) – typically $400–$600.
- Conventional flooded lead-acid battery (less common for newer 335i with Start-Stop; may appear in non-Start-Stop configurations) – typically $120–$200.
Prices above are approximate and vary by region, retailer, and whether you buy online or in-store. Always verify fitment for your exact model year and whether your vehicle requires an AGM battery.
Installation, coding, and disposal
Installation costs depend on location and shop. Expect labor charges of roughly $50–$150 for installation, plus any battery registration or coding required to synchronize with the car’s battery management system, which can add $0–$100. Don’t forget disposal fees for the old battery are usually included or minimal.
OEM batteries often come with longer warranties (2–5 years). Aftermarket options vary, typically offering 1–4 year warranties, with coverage subject to installation quality and usage conditions.
Where to buy and what to ask
Check prices at BMW dealerships, independent auto shops, and online retailers. When shopping, ask about: compatibility with Start-Stop, capacity (Ah and CCA), warranty length, whether a core exchange is required, and whether battery registration or coding is necessary after installation. If your 335i has warnings related to the battery, have a shop diagnose potential electrical issues beyond the battery itself.
What to expect during replacement
Replacing the battery on a BMW 335i is straightforward but may require removing interior trim and trunk panels. Expect the process to include battery removal, terminal cleaning, installation of the correct AGM unit, reconnection of cables, and any required battery management system initialization or coding.
In summary, you’re looking at a broad range: roughly $200–$350 for the battery itself ( aftermarket), $50–$150 for installation, and $0–$100 for coding/registration, resulting in a total of about $300–$800 depending on the specifics of your car and the shop.
Summary: For a BMW 335i, a replacement battery generally costs between $200 and $600 for the battery, with out‑the‑door costs typically ranging from roughly $300 to $800 once installation and any programming are included. OEM AGM batteries are pricier, while reputable aftermarket AGM options can save money while remaining compatible with Start-Stop systems.
