Modern vehicles equipped with start-stop systems place considerable strain on conventional lead-acid batteries, demanding a power source capable of withstanding repeated deep cycling without degradation. The Powermax PM057AGM is an Absorbent Glass Mat battery engineered specifically to meet these requirements, delivering reliable cranking performance and sustained energy recovery in stop-start applications.
Powermax batteries are constructed to exacting specifications, with the AGM design utilising tightly compressed glass mat separators that immobilise the electrolyte, eliminating acid stratification and enabling efficient charge acceptance. This construction supports the rapid charge and discharge cycles characteristic of regenerative braking and frequent engine restarts.
The PM057AGM operates at 12V with a 45Ah capacity and a Cold Cranking Amps rating of 370A (EN). Physical dimensions are 236mm (L) × 125mm (W) × 220mm (H), housed in a B24 case. The battery features a Type 3 terminal arrangement with positive polarity code 1 (positive terminal to the right). It cross-references directly to the industry-standard 057AGM fitment group.
This battery is also available in alternative capacities within the Powermax AGM range: PM005LAGM, PM027AGM, and PM053AGM.
The PM057AGM is supplied with a 3-year warranty, providing confidence in long-term dependability.
