lead-acid batteries

**Lead-Acid Batteries**

Lead-acid batteries are one of the oldest and most widely used types of rechargeable batteries. They consist of lead dioxide and sponge lead plates immersed in a sulfuric acid electrolyte. Known for their reliability, cost-effectiveness, and ability to deliver high surge currents, lead-acid batteries are commonly used in automotive starting, backup power systems, and renewable energy storage. Despite being heavier and having lower energy density compared to newer battery technologies, their robustness and recyclability make them a popular choice in many applications.
