Product Number: LH421
Variations
Maintaining reliable starting performance in classic and vintage vehicles presents a distinct challenge: modern 12V replacements are simply incompatible with period-correct 6V electrical systems. The Lucas LH421 Vintage Battery addresses this directly, offering a purpose-built 6V lead-acid battery engineered for heritage cars, classic commercial vehicles, and agricultural machinery that retain their original low-voltage wiring and charging infrastructure.
Manufactured under the Lucas Automotive brand, the LH421 draws on decades of UK automotive battery expertise. As a standard flooded lead-acid design within the Lucas Vintage product group (Group 2220), it delivers consistent cranking capability suited to the modest demands of vintage powertrains, with 270 CCA (EN) and a 58Ah capacity (C20) supporting dependable cold-weather starting.
The LH421 measures 174mm × 169mm – 218mm (L × W × H, including terminal height) and weighs approximately 9kg. It uses a Type 1 terminal configuration with Standard polarity (Polarity 0) and a B00 hold-down specification. This battery cross-references directly to the 421 battery type. Compatibility with start-stop systems is not confirmed – refer to the product label before fitment.
A variant is available: LH291 (PID000199230). Related Lucas Vintage batteries include EA472, EA530, EA612, EA640, and EA654 for alternative capacity and fitment requirements.
The LH421 is backed by a 1-year manufacturer's warranty, providing assurance of build quality and performance under normal operating conditions.
