Lyijyhappoakut, also known as lead-acid batteries, are a type of rechargeable battery technology. They were first invented in 1859 by French scientist Gaston Planté. This makes them one of the oldest forms of rechargeable electrical energy storage.

The fundamental principle of a lead-acid battery involves a reversible chemical reaction between lead plates and a sulfuric acid electrolyte. During discharge, lead dioxide on the positive plate and sponge lead on the negative plate react with sulfuric acid to produce lead sulfate and water. This process generates electrical current. When the battery is recharged, the chemical reaction is reversed, converting the lead sulfate back into lead dioxide and lead, and freeing up the sulfuric acid.

Lead-acid batteries are characterized by their robustness, reliability, and relatively low cost. They are widely used in automotive applications as starter batteries, providing the high surge of current needed to crank an engine. They are also commonly found in uninterruptible power supplies (UPS), emergency lighting systems, and as backup power sources in various industrial settings.

Despite their advantages, lead-acid batteries have limitations. Their energy density is relatively low compared to newer battery technologies, meaning they are heavier and bulkier for a given amount of energy storage. They also have a finite number of charge-discharge cycles and can be sensitive to deep discharge, which can reduce their lifespan. Environmental concerns related to lead content also necessitate proper recycling and disposal practices.
