What is the difference between starter batteries and deep cycle batteries?


A starter battery is designed to provide a large burst of current for a short period of time. This surge of current turns the engine over during the starting process then the alternator takes over. The burst of energy only discharges the battery 1- 3% then is topped off by the alternator. Under normal use your car battery may go through its entire life without ever being drained more than 20 percent of its total capacity.

Starter battery = single bust of energy

When should I use a starter battery? For starting your car, motorcycle, or other gasoline engine. Since this battery is used for starting the engine only we recommend a basic lead acid starter battery. Lithium batteries have much higher capabilities then a lead acid starter battery. But those capabilities are not needed for starting engines. Most of the power for the car comes from the gasoline engine, and not the battery. This is a scenario where a lead acid battery is an adequate choice.

A deep cycle battery is designed to provide a steady amount of current over a long period of time. A deep cycle battery is also designed to be deeply discharged and charged over and over again without shortening the lifespan of the battery. Dakota Lithium batteries can be drained to 10% of their total capacity before needing to be recharged and are good for 2000 to 5000 discharge/charge cycles.

Deep cycle battery = steady, continuous power for a long time

When should I use a deep cycle battery? When you need continuous power for a long time. Dakota Lithium lives in the deep cycle. A Dakota Lithium battery will last twice as long as a sealed lead acid battery on a single charge, giving you double the usable power. Plus it weighs half as much, and lasts 5x longer.

In addition, if you are looking to store solar power, Dakota Lithium iron phosphate batteries (LiFePO4) are the most efficient battery chemistry for solar energy. 96% of the solar energy collected is able to be used when stored in a Dakota Lithium battery, vs. 76% for a sealed lead acid battery.

Dakota Lithium specializes in creating high capacity deep cycle 12 Volt lithium batteries ranging from 10 amperes hours to 170 amperes hours and beyond for a variety of applications and devices that require a long steady charge. Dakota Lithium does not manufacture starter batteries for cars or motorcycles.
