The Bosch S4 series of batteries is a high-quality line of lead-acid batteries known for their reliability and excellent starting power. They are designed for a wide range of vehicles, including passenger cars and light commercial vehicles. Bosch S4 batteries provide optimal performance even in extreme weather conditions and are characterized by a long service life. Thanks to advanced technologies such as the PowerFrame grid, these batteries offer enhanced resistance to corrosion and maintain stable electrical performance throughout their lifespan.
The Bosch S40 18 model is a 40 Ah battery with a maximum starting current of 330 A. With its compact dimensions – 187 mm in length, 127 mm in width, and 227 mm in height – it fits the B19 standard, which is more commonly found in Asian vehicles than European ones. This battery is an ideal choice for smaller passenger cars, motorcycles, and some compact vehicle models.
A notable feature of this model is its terminal layout type 0, meaning the positive (+) terminal is on the right side. Additionally, the Bosch S40 18 is equipped with type 3 terminals, which are thinner than standard European terminals, a characteristic typical of batteries used in Japanese and Korean cars.
It is also worth noting the mounting type – this model uses the less common B0 mounting system, meaning that before purchasing, it is essential to ensure compatibility with the specific vehicle model.
The Bosch S40 18 battery is comparable to other popular models on the market, such as Exide Excell EB356, Lucas Premium LP054, and Varta Blue Dynamic A14. All of these models have similar electrical specifications and share the same B19 standard size (187x127x227 mm), making them interchangeable in many Asian vehicles.
