Kurşun-asit is a type of rechargeable battery that uses lead dioxide and sponge lead as electrodes, with sulfuric acid as the electrolyte. This design allows for the storage and release of electrical energy, making it a popular choice for various applications, including automotive batteries and backup power systems. These batteries are known for their reliability and cost-effectiveness. However, they are heavier and have a shorter lifespan compared to newer technologies like lithium-ion batteries. Despite this, kurşun-asit batteries remain widely used due to their ability to deliver high surge currents and their recyclability.
