Original Positive Battery Main Power Cable (Positive Terminal) – 4K0971227K

Original factory positive battery cable (main positive power cable / 12V battery distribution and power cable – Batteriekabel Plus / Plusleitung Batterie), designed for Audi A7 Sportback, S7 and RS7 (4K / 4K8 generation), as well as Audi A6 C8 (type 4K2 / 4K5 / 4KA) produced from model year 2018 to 2026, including versions with 3.0 V6 TFSI (55 TFSI / 340 hp), 2.0 TFSI (40/45 TFSI), S7 and RS7 variants, and TDI diesel engines with Mild Hybrid (MHEV 48V) systems, based on the MLBevo modular longitudinal platform.

Original VAG high-current electrical system component. Made from a flexible, thick conductor of pure electrolytic copper with a large cross-sectional area, ensuring minimal resistance and no voltage drops during engine cranking. Protected by thick, factory insulation resistant to abrasion, high thermal loads, and electrolyte exposure. Finished with a factory lead-copper terminal for the positive battery post, featuring a solid clamping screw and heavy-duty ring connectors for direct connection to the main fuse box / power distribution unit in the trunk. Version without integrated pyrotechnic charge (simple, durable power line). Responsible for stable power transfer between the battery and the onboard electrical system power rail.

Fitment guarantee and VIN verification

Every power cable undergoes circuit continuity testing, copper conductor resistance testing, and mechanical terminal clamp inspection before being prepared for shipping.

Fitment / installation note: The initial designation 4K0 (electrical system group 971 / 227) with index K defines the factory positive power cable section mounted directly on the 12V battery post. In newer Audi A7/A6 models with 48V modules, the emergency disconnect system is sometimes separated or implemented directly on the main distribution rail, making the terminal connection cable itself a single, traditional power conductor. Damage to this cable most often results from over-tightening the clamping screw with a regular wrench without proper feel, or from the terminal casting cracking due to material fatigue. The offered cable is fully original, has an undamaged terminal and factory-crimped ends, eliminating the problem of voltage drops during cranking. Before purchase, we recommend comparing the letter index or verifying it using the vehicle's VIN.
