Modern vehicles equipped with start-stop systems place significant demands on auxiliary power management, requiring a battery that can sustain electrical loads independently of the main cranking unit. The Bosch S5 AX2 Auxiliary AGM Battery addresses this requirement as a dedicated auxiliary battery, providing supplementary power to support vehicle electronics, comfort systems, and energy recuperation functions within start-stop architectures.
Manufactured by Bosch under the S5A AGM range, this battery employs Absorbent Glass Mat construction in which the electrolyte is fully absorbed within glass fibre separators. This sealed, maintenance-free design delivers superior cycle stability and resistance to vibration compared with conventional flooded batteries, making it well suited to the continuous charge and discharge demands of modern automotive energy management systems.
Rated at 12V with a capacity of 8Ah (C20) and a Cold Cranking Amps rating of 125A (EN), the S5 AX2 measures 150mm × 87mm – 105mm (L × W × H). Terminal placement and case type are not specified; please verify polarity from the product label prior to installation. No direct cross-references are available for this part number.
This battery is available in related variants within the S5A AGM auxiliary range: S5AX1, S5AX3, and S5AX4, accommodating differing capacity requirements across vehicle applications." 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.
