Starting batteries are specialized batteries designed to provide a quick burst of energy to start an engine. They are commonly used in vehicles, such as cars and trucks, where they deliver a high current for a short duration to crank the engine. These batteries are typically lead-acid types, which are known for their ability to deliver high power. Unlike deep-cycle batteries, which are made for prolonged energy discharge, starting batteries are optimized for rapid discharge. They have thinner plates and a higher surface area, allowing them to generate the necessary power quickly. This makes them essential for reliable engine starting in various vehicles and machinery.
