Product Number: S5AX4
Variations
Auxiliary battery circuits in modern vehicles – particularly those equipped with start-stop systems, advanced infotainment, or secondary electrical loads – demand a dedicated power source capable of stable, repeated charge-discharge cycling. The Bosch S5 AX4 (0092S5AX40) is a 12V 13Ah Absorbent Glass Mat auxiliary battery engineered to meet those demands without compromise.
Built to Bosch S5A AGM specification, the S5 AX4 employs an absorbent glass mat construction in which the electrolyte is immobilised within tightly wound fibreglass matting. This design eliminates free acid, permits operation in any orientation, and delivers the deep-cycle resilience required by vehicles where the auxiliary battery is subject to frequent partial-state-of-charge conditions. A 200A cold cranking amp rating (EN) confirms robust current delivery across a wide operating temperature range.
The battery measures 150mm (L) × 87mm (W) × 145mm (H including terminal) and weighs 4.76kg. Terminal placement and polarity must be confirmed against the product label prior to installation. No direct cross-references are listed; fitment should be validated against the vehicle manufacturer's specification. Start-stop compatibility is supported by the AGM technology, but verify against the product label.
The S5 AX4 is available as part of a range that includes the S5AX1, S5AX2, and S5AX3, offering alternative capacities to suit different auxiliary circuit requirements." Supplied with a 1-year warranty covering defects in materials and workmanship under normal operating conditions. "Standard delivery: 1–3 working days within UK mainland. 30-day returns.

A. The Bosch S5AX4 is a 12V battery with a rated capacity of 13Ah (C20) and a cold cranking amp rating of 200A (EN).
A. AGM stands for Absorbent Glass Mat. In this construction, the electrolyte is held within fibreglass matting rather than remaining as free liquid. This makes the battery spill-proof, vibration-resistant, and capable of withstanding the repeated partial-state-of-charge cycling that auxiliary battery circuits typically impose.
A. The battery measures 150mm in length, 87mm in width, and 145mm in height including the terminal. It weighs 4.76kg.
A. Terminal polarity must be confirmed directly against the label on the product upon receipt. Polarity information is not pre-specified for this SKU, so please check before installation to avoid incorrect connection.
A. The AGM technology used in the S5AX4 is inherently suited to start-stop applications. However, compatibility must be verified against the product label and your vehicle manufacturer's specification before fitting.
A. The Bosch OEM part number for this battery is 0092S5AX40.
A. Yes. The S5AX4 is one of four variants in the range. The S5AX1 (PID000199755), S5AX2 (PID000199756), and S5AX3 (PID000199757) offer alternative capacities for different auxiliary circuit requirements.
A. No direct cross-references are listed for this SKU. Fitment suitability should be confirmed against your vehicle manufacturer's technical specification or by consulting a qualified technician.
A. The S5AX4 is supplied with a 1-year manufacturer's warranty covering defects in materials and workmanship under normal operating conditions.
