Older commercial vehicles and vintage machinery frequently require 6-volt battery systems that are no longer stocked as standard across mainstream supply chains. The Numax 531 Classic CV Battery addresses this requirement directly, offering a purpose-built 6V flooded lead-acid solution for heritage trucks, agricultural equipment, and classic commercial vehicles that demand period-correct electrical specifications.
Manufactured under the Numax Commercial range, this battery is built to a high specification designed to meet the sustained electrical demands of commercial and vintage applications. Numax engineering prioritises durability and consistent cranking performance across varied operating conditions, with a cold cranking amps rating of 450A (EN) providing reliable engine starting performance.
The 531 measures 319mm × 173mm – 222mm (L × W × H) and delivers a capacity of 135Ah (C20) at 6 volts, weighing 24.7kg. It features a Type 1 terminal configuration with standard polarity (positive right, code 0) and a B00 hold-down arrangement. No direct cross-references are listed; buyers should verify fitment against their vehicle's battery tray dimensions and electrical specification prior to ordering. Start-stop compatibility is not confirmed – refer to the product label.
This product is available as part of a range of Numax Classic CV batteries. Variants include SKUs 612, 620, 622, 623, 624, 625, 629, 629UR, and 632, covering a range of capacities and fitments within the same Classic CV family.
