Crown 4D-HD: 12V Group 4D Heavy Duty Commercial Starting Battery

The Crown 4D-HD is a professional-grade 12-Volt starting battery engineered for the high-amperage demands of heavy-duty commercial transportation, earth-moving equipment, and marine vessels. As part of Crown’s Heavy Duty (HD) lineup, this Group 4D battery is built to provide reliable ignition for large-displacement diesel engines. Delivering a powerful 1000 Cold Cranking Amps (CCA), the 4D-HD combines massive starting torque with industrial-strength durability to ensure consistent performance in the most grueling environments.

Engineered for Maximum Durability

• High-Torque Cranking: 1000 CCA and 1250 CA provide the massive electrical surge required for heavy machinery and large diesel engines.
• SolidCast™ Grid Technology: Features full-frame industrial grids with uniform wire thickness to better retain active material and resist internal corrosion.
• Vibration-Resistant Construction: Engineered with reinforced internal connectors and high-density separators to withstand the mechanical stress of off-road and industrial use.
• Rugged Enclosure: Built with high-impact materials to prevent damage from environmental stress and physical impact in farm or construction settings.
• Maintenance-Accessible: Removable vent caps allow for easy electrolyte monitoring, enabling fleet managers to maximize the battery's service life.
• Made in the USA: Manufactured to exacting professional standards in Fremont, Ohio, for guaranteed reliability.
