The GS Yuasa Auxiliary AGM series is specifically designed to support modern vehicles equipped with advanced electrical systems, including hybrid and start-stop technology. AGM (Absorbent Glass Mat) technology provides superior resistance to deep discharge cycles, making these batteries ideal for applications that require a reliable and long-lasting power source. Unlike conventional lead-acid batteries, AGM batteries feature a sealed design that eliminates the risk of leaks and significantly reduces maintenance requirements. The GS Yuasa Auxiliary AGM series is engineered to deliver stable voltage levels, ensuring optimal performance of vehicle electronics, even under high-demand conditions.
The GS Yuasa HJ-S46B24R is a compact AGM battery with a capacity of 45Ah and a maximum starting current of 325A. This battery is specifically designed for auxiliary power applications in hybrid and advanced start-stop vehicles, where sustained power output and deep cycling capabilities are essential. Its AGM construction ensures enhanced durability and a longer lifespan compared to traditional flooded batteries. With its compact dimensions of 238 mm in length, 129 mm in width, and 227 mm in height, this battery falls within the B24 size category, a standard commonly found in Japanese and hybrid vehicles.
One of the notable characteristics of the HJ-S46B24R is its unique terminal configuration. Unlike most European batteries, this model features a positive terminal located on the left side (layout 1). Additionally, it is equipped with type 3 terminals, which are thinner than standard European terminals and are commonly found in Japanese vehicles. This specific terminal design ensures compatibility with a range of hybrid and electric vehicles that require smaller terminal connections.
Another distinctive feature of the HJ-S46B24R is its B00 mounting system. Unlike standard B13 mounting systems, which secure the battery with a full perimeter clamp, the B00 configuration lacks mounting flanges or bottom ledges, meaning it relies on top clamps or side brackets for secure installation. This mounting style is less common in European vehicles but is frequently used in Japanese automotive applications, particularly in hybrid models that require a lightweight and space-efficient battery.
When compared to similar batteries, such as the Optima Yellow Top AGM YT S 2.7J, the GS Yuasa HJ-S46B24R offers a slightly higher capacity (45Ah vs. 38Ah) but a lower cranking power (325A vs. 460A). However, the GS Yuasa model maintains excellent deep-cycle performance and stable power output, making it a highly reliable choice for vehicles requiring auxiliary battery support. Both batteries share the same B24 size classification and B00 mounting system, ensuring compatibility with similar applications.
Overall, the GS Yuasa HJ-S46B24R is an excellent choice for drivers seeking a high-performance auxiliary AGM battery for hybrid or start-stop vehicles. Its advanced technology, compact design, and unique terminal configuration make it an ideal solution for vehicles requiring specialized power management. With its superior deep-cycle durability and maintenance-free operation, this battery provides reliable and consistent performance for modern automotive electrical systems.
