Lead batteries are used across a wide range of industries and applications from transportation to communication networks. When people think about lead acid batteries, they usually think about a car battery. These are starting batteries. They deliver a short burst of high power to start the engine. There are also deep cycle batteries.
A typical lead–acid battery contains a mixture with varying concentrations of water and acid. Sulfuric acid has a higher density than water, which causes the acid formed at the plates during charging to flow downward and collect at the bottom of the battery.
The lead acid batteries were introduced in the year 1859 by Gaston Plante. It is one of the oldest rechargeable batteries, the first available for commercial use. This secondary battery thus had a huge acceptance in the market. Since then, lead-acid batteries have been used in most rechargeable battery applications.
Construction, Working, Connection Diagram, Charging & Chemical Reaction Figure 1: Lead Acid Battery. The battery cells in which the chemical action taking place is reversible are known as the lead acid battery cells. So it is possible to recharge a lead acid battery cell if it is in the discharged state.
They offer a small energy-to-volume ratio and a very low energy-to-weight ratio. Lead-acid batteries are used in numerous applications to utilize the advantage of rechargeable batteries. Some of them are replaced with modern technologies like lithium-ion batteries. But Lead acid batteries are still the perfect choice in numerous other applications.
From that point on, it was impossible to imagine industry without the lead battery. Even more than 150 years later, the lead battery is still one of the most important and widely used battery technologies. Lead-acid batteries are known for their long service life.
