AGM Start/Stop Technology

AGM (Absorbent Glass Mat) technology is designed for vehicles that place significantly greater demands on the starter battery than a conventional starting system. The electrolyte is retained within absorbent glass-fibre separators, helping provide excellent charge acceptance, cyclic durability and reliable power delivery even under demanding operating conditions.

In an advanced Start/Stop vehicle, the engine may switch off whenever the vehicle comes to a stop while systems such as lighting, climate control, infotainment, navigation and safety equipment continue drawing power. The battery must then restart the engine repeatedly throughout the journey. The Bosch S5A15 is engineered to withstand these demanding operating cycles while providing the high starting performance required by larger modern vehicles.

Type 020 Fitment

The Bosch S5A15 uses the large Type 020 / L6 battery format measuring approximately 393 × 175 × 190mm. This is one of the larger common European passenger vehicle battery sizes and is typically specified where high capacity and strong starting performance are required. Always check that the vehicle has sufficient battery tray space and that the terminal layout, hold-down arrangement and original battery specification match before ordering.

Important AGM Replacement Information

If your vehicle was originally equipped with an AGM battery, the replacement should also be an AGM battery of an appropriate specification. An AGM battery should not normally be downgraded to an EFB or conventional flooded battery, even if the physical dimensions are compatible, as these technologies may not provide the cycling performance and charge acceptance required by the vehicle.

Many vehicles using a battery of this specification also feature a Battery Management System (BMS). Following replacement, the new battery may need to be registered or coded to the vehicle so that the charging system can correctly manage the new battery. Always check the vehicle manufacturer's requirements before installation.
