What is the difference between Deep Cycle, Dual Purpose, Cranking Batteries?

Lithium batteries are becoming increasingly popular for use in a variety of applications, including marine, RVs, and off-grid systems. There are three main types of lithium batteries: deep cycle, dual purpose, and cranking. Each type is designed for specific purposes and has unique characteristics that make it better suited for certain applications.

Deep Cycle

Deep cycle lithium batteries are designed to be discharged and recharged on a regular basis. They are typically used for applications that require a consistent and reliable source of power, such as powering a trolling motor or a house battery bank in an RV. These batteries have a relatively low peak current output, but are able to provide a steady flow of current over a long period of time. Deep Cycle batteries can be put in series or ran parallel. Deep cycle lithium batteries can come in 12V, 24V, 36V, and 48V.

Dual Purpose 

Dual purpose lithium batteries are a hybrid of deep cycle and cranking batteries. They are designed to provide both deep cycle power and high current output for starting engines. These batteries are a good choice for applications that require both a reliable power source and the ability to start an engine, such as in a boat with both a trolling motor and an outboard engine. These batteries can be ran in series or in parallel. For engine starting purposes, 12V would be required.

Cranking/Starting

Cranking lithium batteries, also known as starting batteries, are designed to deliver a high burst of current for a short period of time in order to start an engine. They are not meant to be deeply discharged and recharged on a regular basis like deep cycle batteries. Instead, they are used to provide the initial burst of power needed to start an engine, and are then recharged by the engine's alternator as the vehicle is running. These batteries are classified by Marine Cranking Amps or Cold Cranking Amps, be sure to look for minimum requirements for your motor in the manual.

Conclusion

In conclusion, deep cycle, dual purpose, and cranking lithium batteries are each designed for specific purposes and have unique characteristics that make them better suited for certain applications. Deep cycle batteries are ideal for providing a consistent and reliable source of power, dual purpose batteries are a good choice for applications that require both deep cycle power and high current output, and cranking batteries are designed to deliver a high burst of current for starting engines.
