The Bosch S5 battery series stands at the top of Bosch’s range of conventional flooded lead-acid batteries, offering exceptional performance, reliability, and long service life. Designed for drivers who expect premium quality and high starting power, the S5 range combines innovative PowerFrame® grid technology with robust internal construction. This ensures maximum current flow, superior corrosion resistance, and minimal self-discharge. Bosch S5 batteries are engineered to provide consistent energy even in demanding conditions such as cold climates or vehicles with multiple electrical accessories. They are maintenance-free and built to deliver up to 30% longer service life compared to standard batteries. With their outstanding cold-start performance, the S5 series is ideal for high-performance vehicles and modern European cars that require stable voltage and strong cranking power.
The Bosch S50 07 is a 12V lead-acid battery within the S5 family that embodies these qualities. It offers a capacity of 74 Ah and an impressive cold cranking current of 750 A, making it well-suited for mid-size and larger vehicles, including sedans, SUVs, and diesel-powered cars. With its dimensions of 278 mm in length, 175 mm in width, and a reduced height of 175 mm, the S50 07 corresponds to the H6/LB3 European size standard. This lowered height version allows for installation in vehicles that require a more compact battery profile while still maintaining excellent energy reserves and power output. The battery uses the standard European polarity layout (layout 0 – positive terminal on the right) and terminal type 1, ensuring compatibility with a broad range of vehicles. Its B13 base hold-down fits securely in most European battery trays.
As a conventional flooded battery, the Bosch S50 07 is not suitable for vehicles equipped with start-stop systems, which require EFB or AGM technology to withstand frequent charging and discharging cycles. Nevertheless, for cars without such systems, it provides optimal reliability and longevity. The improved internal design and PowerFrame® grids ensure excellent charge acceptance and high electrical stability, even during intensive use. The battery’s robust casing and vibration-resistant structure make it ideal for long-distance drivers and those who regularly use their cars in varying weather conditions. Thanks to Bosch’s precision manufacturing and quality control, the S50 07 maintains its performance over time, delivering quick and confident starts in all seasons.
When compared to similar batteries on the market, the Bosch S50 07 represents the highest level of performance among standard lead-acid models. For example, compared to the Bosch S40 07 (72 Ah, 680 A), it offers significantly higher cranking power and energy reserve, making it a better choice for more demanding applications. It also outperforms the Bosch S3 S30 07 (70 Ah, 640 A) by providing roughly 15% more starting power. Among competitors, the Exide Premium EA722 (72 Ah, 720 A) and the Varta Silver Dynamic E38 (74 Ah, 750 A) come closest in terms of specifications. However, Bosch’s PowerFrame® technology gives the S50 07 a distinct edge in durability and voltage stability, which are crucial for powering modern electronics and onboard systems. Compared to mid-range options like the Exide Excell EB712 (71 Ah, 670 A) or the Varta Blue Dynamic E43 (72 Ah, 680 A), the S50 07 offers superior performance under load and improved cold-weather reliability.
Overall, the Bosch S50 07 is an excellent choice for drivers who prioritize dependable starting power, long lifespan, and consistent performance. Its 74 Ah capacity and 750 A cold cranking current make it one of the strongest batteries in its class. With its standard European dimensions and low-profile height, it fits a wide range of popular vehicles from brands such as Volkswagen, Audi, BMW, Ford, and Peugeot. The combination of high-quality materials, innovative grid design, and Bosch’s engineering expertise makes the S50 07 a benchmark in conventional battery technology, providing years of reliable service and worry-free operation.
