The Bosch S4 series consists of high-quality batteries designed for a wide range of vehicles, including both passenger cars and light commercial vehicles. These batteries are known for their excellent manufacturing quality, durability, and reliability under various operating conditions. With modern lead-acid technology, Bosch S4 batteries offer stable performance, long service life, and optimal starting power. They are designed to meet the demands of modern vehicle electrical systems.
The Bosch S40 19 model is a compact battery with a capacity of 40 Ah and a maximum starting current of 330 A. Due to its small dimensions (187x127x227 mm), it fits vehicles with limited mounting space. Its dimensions correspond to the B19 standard, which is less common in Europe but frequently found in Japanese and Asian vehicles.
One of the distinctive features of the Bosch S40 19 is its non-standard terminal layout – layout 1, where the positive terminal is on the left side. This is an important detail when selecting the right battery, as not all vehicle models are designed for this terminal arrangement. Additionally, this battery is equipped with type 3 terminals, also known as thin Japanese terminals. These connectors are standard in Asian vehicles but may require adapters for use in European models.
Another important aspect of this model is the use of the B0 mounting system, which means it lacks the typical lower hold-down found in most European batteries. As a result, installation may require additional securing methods or top-mounted brackets, which are more commonly found in Asian vehicles.
For those looking for a battery with similar specifications, alternatives include the Exide Excell EB357 (35 Ah, 240 A), Lucas Premium LP055 (40 Ah, 360 A), and Varta Blue Dynamic A15 (40 Ah, 330 A). All these models have identical dimensions (187x127x220-227 mm), layout 1, and thin type 3 terminals, making them suitable replacements for the Bosch S40 19.
