Deep-cycle battery

A deep-cycle battery is designed to provide a steady amount of power over a long period by discharging and recharging repeatedly. Unlike regular car batteries, which deliver quick bursts of energy for starting engines, deep-cycle batteries are built to withstand many cycles of dropping to lower charge levels without damage. They’re commonly used in renewable energy systems, solar setups, and marine applications. Their robust design allows them to store and release energy gradually, making them suitable for applications that require sustained power over time.
