How do starting batteries differ from deep-cycle batteries?

Starting batteries are specifically engineered to deliver a high burst of current for a brief duration, which is essential for starting engines. This characteristic is crucial in applications such as marine engines, where a large amount of power is needed for a short time to ignite the engine. Starting batteries achieve this through their design, which includes thinner plates that allow for rapid discharge, enabling them to generate high cranking amps.

In contrast, deep-cycle batteries are designed to provide a steady amount of power over a prolonged period, making them suitable for applications such as powering appliances or systems on a boat when the engine is not running. They can be regularly discharged and recharged without much impact on their lifespan.

Understanding these differences is vital for selecting the right battery for a specific purpose—starting batteries for engine ignition, and deep-cycle batteries for energy storage during extended use.
