Type 054 Fitment

The Bosch S4018 uses the compact Type 054 battery format, measuring approximately 187 × 140 × 227mm. This differs considerably from the wider DIN-style cases used by many modern European vehicles, so the battery should not be selected solely on its Ah or CCA rating.

Always compare the physical dimensions, terminal orientation and mounting arrangement with the battery currently fitted to the vehicle. This is particularly important with Type 054 applications, as similar compact battery types can use different terminal positions or case configurations.

Important Fitment Information

Before ordering the Bosch S4018, always check the specifications of the battery currently fitted to your vehicle. Battery dimensions, terminal position, mounting arrangement, capacity and starting performance should all be compatible with the vehicle manufacturer's requirements.

The S4018 is a conventional lead-acid starter battery intended for vehicles with standard starting systems. It should not be used to replace an EFB or AGM battery where one of those technologies is specified by the vehicle manufacturer for a Start/Stop or energy-management system.
