The 2007 BMW 328i uses a standard 12-volt lead-acid car battery. In most cars from that era, replacement specs center on roughly 70–80 amp-hours of capacity and about 650–760 cold-cranking amps, with the exact group size varying by region and trim. Always verify the precise spec on the existing battery label or in the owner's manual.
For context, the 2007 328i sits in the E90 generation and relies on a conventional 12V battery to power starting and all onboard electronics. BMW’s battery-sensor system means you should match the OEM spec to maintain proper charging behavior and electronics compatibility. Regional variations and equipment options can affect the exact size and rating you need.
Battery basics for the 2007 BMW 328i
Below are the core characteristics to understand when shopping for a replacement, so you pick a unit that fits and functions correctly in your car.
- 12-volt lead-acid battery (most units are maintenance-free sealed designs; some markets may use AGM batteries if the car is equipped with certain high-load electronics)
- Typical capacity around 70–80 Ah for this model year
- Cold-cranking amps (CCA) commonly in the 650–760 A range, depending on climate and exact specification
- Common replacement group sizes seen for this model include 94R or H6 (Group 48 in some regional catalogs); exact fit depends on market and equipment
- OEM-recommended or equivalent battery from reputable brands is advised to ensure compatibility with the vehicle’s battery sensor and on-board electronics
Concluding: Always check the exact group size, Ah, and CCA on the current battery label or in the owner's manual, since regional variations exist.
How to confirm the exact spec for your car
To avoid buying the wrong battery, follow these steps to verify the precise specification for your car configuration.
- Look at the current battery label or the owner's manual for the exact group size, capacity (Ah), and CCA
- Note the terminal layout and orientation to ensure the new battery will fit and connect correctly
- Check whether your vehicle requires an AGM battery (some setups with Start-Stop or high electrical demand in later models) or if a conventional flooded/maintenance-free battery is sufficient
- Use your VIN to pull the BMW-approved part number from the official catalog or confirm with a BMW dealer
- Choose an OEM-equivalent battery from a trusted brand (BMW, VARTA, BOSCH, etc.) that matches the spec and fits BMW’s battery sensor system
- If you’re not comfortable with replacement, have a professional handle installation to preserve memory and avoid electrical issues
Concluding: Verifying these details helps ensure you purchase the correct battery the first time and avoids compatibility problems down the line.
Special cases and practical tips
In practice, most 2007 328i models use a standard 12V battery, but certain high-load configurations or regional equipment sets can push toward AGM. If in doubt, rely on the VIN-based parts lookup or the exact label on the existing battery. When replacing, ensure proper venting, secure mounting, and memory preservation during the swap if you need to reprogram or reset electronic systems later on.
Summary: A 2007 BMW 328i typically uses a 12-volt lead-acid battery with about 70–80 Ah capacity and roughly 650–760 CCA, with the exact group size varying by market and equipment. Always verify the precise spec on the battery label, in the owner's manual, or via a VIN-specific parts lookup, and opt for an OEM-equivalent battery to maintain full compatibility with BMW’s electronics.
