Lead acid is sluggish and cannot be charged as quickly as other battery systems. (See BU-202: New Lead Acid Systems) With the CCCV method, lead acid batteries are charged in three stages, which are constant-current charge, topping charge and float charge.
Despite its lower energy density compared to newer batteries, it remains popular for automotive and backup power due to its reliability. Charging methods for lead acid batteries include constant current charging and constant voltage charging. Constant current charging applies a steady current until the battery reaches full charge.
Constant voltage charging maintains a fixed voltage level, allowing the current to taper off as the battery approaches full charge. Lead acid batteries work through electrochemical reactions. During discharge, lead dioxide and sponge lead react with sulfuric acid to produce lead sulfate and water. During charging, this reaction is reversed.
The main components of a lead acid battery include lead dioxide (PbO2), sponge lead (Pb), and sulfuric acid (H2SO4). When the battery discharges, lead dioxide at the positive electrode reacts with sponge lead at the negative electrode in the presence of sulfuric acid.
Chemical energy is converted into electrical energy which is delivered to load. The lead-acid battery can be recharged when it is fully discharged. For recharging, positive terminal of DC source is connected to positive terminal of the battery (anode) and negative terminal of DC source is connected to the negative terminal (cathode) of the battery.
Flooded lead acid batteries are a type of rechargeable battery that uses a liquid electrolyte solution of sulfuric acid and water. They are commonly used in applications like automotive starting, uninterruptible power supplies, and renewable energy systems.
