The Bosch S4 battery series is one of the most popular choices among car owners, offering high quality and reliability at an affordable price. Bosch S4 batteries are lead-acid models that perform well in both passenger cars and light commercial vehicles. Thanks to modern manufacturing technology, they ensure long service life, high resistance to frequent engine starts, and stable performance in various weather conditions. This series is recommended for cars with basic electrical equipment as well as vehicles that require slightly higher power. The Bosch S40 22 model is a compact battery with a capacity of 45 Ah and a maximum starting current of 330 A, making it an excellent choice for smaller passenger cars, especially Japanese and Korean models. Its dimensions are **238 x 129 x 227 mm**, meaning it falls into the **B24 size category**, which is more commonly used in Asian vehicles. This means it does not fit standard European sizes and requires verification to ensure compatibility with the intended vehicle. An important feature of this battery is its **non-standard terminal layout (1)**, meaning the positive terminal is on the left side. This is a crucial detail to consider when selecting a battery, as most European models have the positive terminal on the right (layout 0). The Bosch S40 22 also features **type 3 terminals**, meaning its posts are thinner than standard European ones and are designed for Asian vehicles. Another distinguishing feature of this model is its **less common B0 mounting system**, meaning it does not have standard mounting grooves. This may require the use of adapters or modifications to the vehicle’s battery hold-down system. This is an essential detail for users planning to install the battery themselves.
