Bosch Vehicle Batteries: OEM-Grade Power for Every Drive

When it comes to starting reliability and electrical endurance, few names carry the weight of Bosch. As one of the world's largest automotive suppliers, Bosch brings the same engineering precision found in factory-installed components directly to its vehicle battery lineup. The result is a tiered range of batteries — from economical everyday options to high-performance AGM units — designed to meet the exact demands of modern vehicles.

A Battery for Every Vehicle Type

Bosch structures its passenger vehicle battery lineup around clearly defined performance tiers, making it straightforward to match the right battery to the right application.

• Bosch S3 – The S3 battery offers an economical solution for older vehicles with fewer electrical demands.
• Bosch S4 – The Bosch S4 Battery is a dependable choice for all types of vehicles.
• Bosch S5 – The Bosch S5 Battery is the powerhouse for recent car models with high electronic demand, providing optimum starting power and long service life, flushed tops for minimized risk of acid leakage, and dependable power in accordance with OEM requirements. It uses full frame grid technology, highly protective pocket separators, and robust connections inside to extend lifetime and maximize reliability.
• Bosch S6 High Performance AGM – The Bosch S6 High Performance AGM Battery uses cutting-edge technology that provides constant optimum power even for short trips and stop-and-go traffic, up to 2x longer lifetime, flushed tops for minimized risk of acid leakage, dependable power in accordance with OEM requirements, excellent charge acceptance, and better vibration resistance.

Built for Start-Stop and High-Demand Electronics

The steady increase in comfort and safety features on today's vehicles, combined with more sophisticated driving systems, has created an exponential surge in the demand for power — and Bosch has significantly enhanced its passenger vehicle battery program to meet today's rigorous demands for power, performance, and capacity.

The S6 AGM is the only choice for start-stop vehicles and is made with full frame grid technology, acid-absorbing micro fiber glass mats, and extra robust connections inside to extend lifetime and maximize reliability. For drivers whose vehicles use brake energy recuperation, Bosch's S5 EFB technology and S6 AGM technology serve as high-performance energy sources for frequent starts — particularly with start/stop systems — while staying connected to the vehicle's energy management system.

Warranty Coverage and Roadside Assistance

Bosch backs its entire maintenance-free battery lineup with strong warranty coverage. All Bosch 100% maintenance-free batteries come with a free replacement warranty: 1 year on the S3, 2 years on the S4, 3 years on the S5, and 4 years on the S6 High-Performance AGM. In addition, Bosch offers a free roadside assistance program on the S4, S5, and S6 AGM batteries.
