Modern vehicles equipped with start-stop systems place extraordinary demands on conventional flooded batteries, cycling repeatedly through charge and discharge sequences that standard lead-acid technology cannot sustain reliably. The Numax 012AGM is an Absorbent Glass Mat battery engineered specifically to meet these elevated requirements, delivering dependable cranking power and cycle stability for start-stop-equipped cars and other demanding 12V automotive applications.
Numax batteries are built to the highest specification to cope with today's automotive electrical demands. The AGM construction immobilises the electrolyte within a tightly compressed glass mat separator, eliminating acid stratification, reducing internal resistance, and enabling the battery to accept high charge currents from regenerative braking systems. The result is a unit that recovers rapidly between engine-off events and maintains consistent cold cranking performance across its service life.
The 012AGM operates at 12V with a 50Ah capacity (C20) and 520A Cold Cranking Amps (EN). Its physical dimensions are 207mm × 175mm – 190mm including terminal height, housed in an L01 case. Terminal layout is Type 1 with standard polarity (positive left, code 0), and the hold-down configuration is B13. The manufacturer cross-reference for this unit is 012AGM. Weight is 15.9kg.
This battery is available across a range of sizes and formats within the Numax AGM range. Related variants include 005LAGM, 027AGM, 005RAGM, 053AGM, 054AGM, 055AGM, 057AGM, NTS16CLB, and NTS51913, accommodating differing capacity and fitment requirements.
The 012AGM is backed by a 3-year warranty, providing dependable service life and reliable performance under everyday driving conditions.
