Modern vehicles equipped with start-stop systems place significantly greater demands on their batteries than conventional automotive applications, requiring a technology capable of withstanding repeated deep discharge and recharge cycles without degradation. The Numax 057AGM is an Absorbent Glass Mat battery engineered specifically to meet these demands, delivering reliable cranking power and cycle stability for cars fitted with energy recovery and start-stop technology.
Numax batteries are built to the highest specification to cope with today's automotive electrical demands, combining quality materials with rigorous manufacturing standards. The AGM construction immobilises the electrolyte within glass mat separators, eliminating acid stratification, reducing internal resistance, and enabling the battery to accept charge rapidly from regenerative braking systems – a requirement of modern fuel-saving drivetrains.
The 057AGM operates at 12 volts with a 45Ah capacity (C20) and a Cold Cranking Amp rating of 370A (EN), providing dependable engine starting across a broad range of conditions. Physical dimensions are 236mm × 125mm – 220mm (L × W × H) with a B24 case size, Type 3 terminal posts, and standard polarity (positive right, Layout 1). The unit weighs 13kg. Cross-reference code: 057AGM. Compatible hold-down type: B00.
This battery is available across a range of sizes and fitments within the Numax AGM series, including 005LAGM, 027AGM, 005RAGM, 012AGM, 053AGM, 054AGM, 055AGM, NTS16CLB, and NTS51913, accommodating a wide variety of vehicle applications.
The Numax 057AGM is supplied with a 3-year warranty, providing assurance of durability and reliable performance under everyday driving conditions.
