Plus, the widespread availability of lead-acid batteries and the infrastructure for their maintenance and recycling makes them a convenient option for golf cart users everywhere. They're like the dependable friend you can always count on!

Lead-acid batteries for golf carts are comprised of several key components that work together to store and provide electrical power. The fundamental element is the battery cell, which is the basic unit that produces electricity through a chemical reaction. Each cell typically consists of a set of lead plates: one set is made of lead (Pb) and the other set is made of lead dioxide (PbO2). These plates are submerged in an electrolyte solution, usually sulfuric acid (H2SO4) and water (H2O). When the battery is discharging, the lead plates react with the sulfuric acid, producing lead sulfate (PbSO4) and releasing electrons. This flow of electrons generates electrical current that powers your golf cart. During charging, the process is reversed. The electrical energy from the charger forces the lead sulfate back into the lead plates and lead dioxide, restoring the battery's chemical composition and its ability to provide power. The cells are housed in a battery case, which is designed to protect the internal components and contain the electrolyte. Multiple cells are typically connected in series to increase the voltage. This configuration, along with the specific capacity of the cells, determines the battery's total voltage and amp-hour (Ah) rating. The Ah rating signifies the amount of current the battery can deliver over a period of time. Connectors or terminals allow the battery to be connected to your golf cart's electrical system, and they facilitate the flow of current. The battery's design and construction allow it to repeatedly discharge and recharge over its lifespan, making it a sustainable power source for golf carts. So, with this basic knowledge in hand, you're ready to get to the core of it!
