How Does Lead-Acid Batteries Work?
When a lead-acid battery is charged, a chemical reaction occurs that converts lead oxide and lead into lead sulfate and water. This reaction occurs at the positive electrode, …
Charging and Discharging of Lead Acid Battery
The lead–acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté. It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead–acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents. These features, along with their low cost, make them attractive for u…
