Dual Purpose

A Dual Purpose (DP) battery is designed to provide both starting power and sustained energy for applications that require both capabilities. Because DP batteries are designed differently from dedicated deep cycle or dedicated starting batteries, always refer to the specifications of the specific DP battery for its charging, capacity, continuous current, and cranking capabilities.

Dakota Lithium DL+ Dual Purpose batteries provide up to 1,000 CCA of engine-starting power, depending on the specific model. The DL+ line is designed to provide both high-current engine starting and deep-cycle performance, making it suitable for applications that require starting power as well as sustained energy. Always check the specifications of the specific battery to ensure it meets your engine's starting requirements.

Yes, Dual Purpose batteries are designed for applications requiring both starting power and sustained energy. However, the specific balance of starting and deep-cycle capability varies by model, so select your battery based on the actual requirements of your application.

Dakota Lithium Dual Purpose batteries should be charged using a LiFePO₄-compatible charging source that meets the voltage and charging-current requirements of the specific battery. The charger should be appropriately sized for the battery’s capacity and maximum charging-current rating.

In vehicle and marine applications, certain Dual Purpose batteries may also be charged through a compatible alternator or vehicle charging system. Depending on the application, a DC-DC charger may be recommended to regulate charging and help protect both the battery and charging system.

Always follow the charging specifications for your specific battery model.

A deep cycle battery is primarily designed for sustained energy delivery and repeated cycling. A Dual Purpose battery is designed to provide both sustained energy and high-current starting capability. The correct choice depends on whether your application requires starting power, deep-cycle performance, or both.
