Q 1. What are the dimensions and weight of the Bosch S4029 battery?

A. The Bosch S4029 measures 306mm in length, 173mm in width, and 225mm in height including the terminal. It weighs 20.73 kg.

Q 2. What is the cold cranking amp (CCA) rating of the S4029?

A. The Bosch S4029 is rated at 830A CCA measured to the EN standard, making it suitable for high-demand cold-start applications in large petrol and diesel vehicles.

Q 3. Is the Bosch S4029 compatible with start-stop vehicles?

A. No. The S4029 is a standard flooded lead-acid battery and is not suitable for vehicles equipped with start-stop, regenerative braking, or micro-hybrid systems. An AGM or EFB battery would be required for those applications.

Q 4. What terminal type and polarity does the S4029 use?

A. The S4029 uses a Type 1 terminal and polarity code 1, meaning the positive terminal is positioned on the right-hand side when viewed from the front of the battery.

Q 5. What hold-down specification does the Bosch S4029 use?

A. The S4029 uses a B01 hold-down specification. It is important to confirm that your vehicle's battery tray and clamp arrangement is compatible with this specification before fitting.

Q 6. What cross-reference codes apply to the Bosch S4029?

A. The S4029 cross-references to the 250H fitment group code. It is also a direct equivalent to Varta batteries listed under the 250H reference. Always verify dimensions, terminal type, and polarity against your vehicle's requirements before ordering.

Q 7. What warranty is provided with the Bosch S4029?

A. The Bosch S4029 is covered by a 4-year manufacturer's warranty under normal operating conditions. The warranty applies to standard vehicle use and does not extend to batteries fitted in start-stop applications.

Q 8. What technology does the Bosch S4 range use?

A. The Bosch S4 range uses full frame grid technology, which distributes electrical current evenly across the plate surface. This reduces internal resistance and slows the degradation of active material, contributing to a longer service life.

A. Yes. The Bosch S4 range includes multiple variants to suit different vehicle requirements. Available alternatives include the S4007, S4008, S4009, S4010, S4011, S4013, S4026, S4027, and S4028, spanning a range of voltages, capacities, and CCA ratings.
