The lead acid battery uses the constant current constant voltage (CCCV) charge method. A regulated current raises the terminal voltage until the upper charge voltage limit is reached, at which point the current drops due to saturation. The charge time is 12–16 hours and up to 36–48 hours for large stationary batteries.
From Battery University a great site for battery knowledge: Lead acid batteries should be charged in three stages, which are 1 constant-current charge, 2 topping charge and float charge. The constant-current charge applies the bulk of the charge and takes up roughly half of the required charge time; the topping charge continues at a lower
Reserve Capacity is the time in minutes that a new fully charged lead acid battery can supply a current of 25amps and maintain a terminal voltage above 10.5v for a 12v or 5.25v for a 6v. This figure usually represents the approximate time that a vehicle will run with a night time electrical load, should its engine charging system fail.

Lead contributes to the function of a lead acid battery by serving as a key component in the battery's electrodes. The battery contains two types of electrodes: the positive electrode, which is made of lead dioxide (PbO2), and the negative electrode, which consists of sponge lead (Pb).
The chemistry of lead-acid batteries involves oxidation and reduction reactions. During discharge, lead dioxide and sponge lead react with sulfuric acid to produce lead sulfate (PbSO4) and water. When recharged, the process is reversed, regenerating lead dioxide, sponge lead, and sulfuric acid.
The construction of lead acid batteries involves several key components. Each battery contains two lead plates, one made of lead dioxide and the other of sponge lead, submerged in sulfuric acid electrolyte. These plates are positioned in a durable container, often made of plastic or glass, ensuring safety and functionality.
The electrolyte in a lead-acid battery is sulfuric acid, which acts as a conductor for the flow of electrons between the lead plates. When the battery is charged, the sulfuric acid reacts with the lead plates to form lead sulfate and water.
Comprising lead dioxide, lead, and a sulfuric acid electrolyte solution, this amalgam forms the bedrock upon which energy storage is built. Within the battery's confines, lead dioxide plates serve as the positive electrode (anode), while lead plates function as the negative electrode (cathode).
