The Bosch S3 battery series is designed for users looking for a durable and reliable battery at an affordable price. With lead-acid technology, these batteries deliver stable performance and resistance to varying weather conditions. Bosch S3 is the perfect choice for vehicles with basic electrical systems, providing daily reliability and peace of mind. This series combines solid performance with the quality one expects from the Bosch brand.

The Bosch S30 17 model is a compact battery with a capacity of 45 Ah and a maximum starting current of 300 A. Measuring 219x135x225 mm, this battery fits within the B13 size category, making it suitable for select vehicle models. However, these dimensions are more characteristic of specific applications, such as older vehicle models or Asian cars. The less common B01 mounting area further highlights its specialized design, requiring dedicated mounting brackets. As a result, the Bosch S30 17 can be used in vehicles where standard B13 mounts are incompatible.

A notable feature of this model is the non-standard 1 terminal layout, where the positive terminal is on the left side. This configuration requires users to ensure compatibility with their vehicle, especially when replacing the battery. The Bosch S30 17 is equipped with type 1 terminals, adding to its versatility and ease of installation in compatible vehicles.

When compared to similar batteries, such as the Varta Black Dynamic B24 (45 Ah, 300 A) and the Exide Excell EB451 (45 Ah, 330 A), the Bosch S30 17 offers comparable performance. However, it stands out for its build quality and reliability, hallmarks of the Bosch brand. It is an ideal choice for users seeking a high-performance battery tailored for specific applications.
