Patented Design

For Premium Performance

Duralast batteries feature a patented design that's powerfully effective - even in extreme conditions.

The rugged, impact-resistant polypropylene construction reduces damage due to vibration.


Duralast batteries feature best-in-class vent caps, a Solidium™ Weld System, Robust Separators, LifeSpan™ negative paste and power designed to meet or exceed your specific vehicles needs. All this adds up to a powerful, long-lasting battery that's worthy of the Duralast name.

Best-in-class vent caps are engineered to be safer, reduce leakage and corrosion, and increase the overall durability.

The extreme bond created by the LifeSpan™ formula improves performance and increases battery life.

Duralast batteries' robust separators are stronger and more stable, leading to fewer battery failures due to shorts.

CircaTech™ negative plates feature patented rounded corners that reduce internal shorts and extend battery life.

Patented stamped-grid technology gives you the high-performance results you need.
