Heavy-duty AGM traction batteries must endure repeated deep-discharge cycles, vibration, and the sustained current demands of start-stop drivetrains – conditions that exceed the tolerance of conventional flooded lead-acid designs. The Lucas AGM31 12V 100Ah AGM battery addresses these requirements with a sealed, valve-regulated absorbent glass mat construction that immobilises electrolyte within the plate stack, eliminating acid stratification and enabling reliable recovery from deep discharge.
Manufactured within the Lucas Automotive Premium CV Battery range (Product Group 2212), the AGM31 is engineered for commercial vehicle and large passenger car applications where cyclic stability and consistent energy delivery are critical. The absorbed glass mat separator design minimises internal resistance, supports recombination of charging gases, and maintains performance across variable charge states – characteristics that make AGM technology the preferred choice for vehicles equipped with regenerative braking, start-stop systems, and high electrical loads." The AGM31 measures 330 mm – 174 mm – 238 mm (L × W × H including terminal) and weighs 31.1 kg. It carries a Type 1 terminal configuration with B00 hold-down provision and Polarity 1 layout. The battery is rated at 12V with a 100Ah capacity (C20). Cross-reference codes are 31-AGM and US AGM 31. Note: start-stop compatibility is supported by the AGM technology; verify suitability with the product label before fitment. "This listing covers the AGM31 variant. Related Lucas AGM batteries available on PartsForMachines include LF017, LF020, LF068, LF069, LF096, LF110, LF115, and LXC25AGM, covering a range of capacities and terminal configurations for alternative fitments.
The AGM31 is supplied with a 1-year warranty against manufacturing defects, providing documented assurance of service life for fleet and workshop purchasers.
