Lead batteries, more accurately known as lead-acid batteries, function through a controlled chemical reaction to produce electricity. Let's break down how this process works:
Essentially, a lead-acid battery is a rechargeable battery that uses both lead and sulphuric acid to work. According to information provided, a controlled chemical reaction is created when the lead is submerged into the sulphuric acid; the chemical reaction causes the battery to produce electricity.

Here's a more detailed explanation:
-
Components: A lead-acid battery consists of:
- Lead plates (the anode and cathode).
- A sulfuric acid electrolyte solution.
-
Discharging (Producing Electricity):
- When the battery is connected to a circuit, a chemical reaction occurs between the lead plates and the sulfuric acid.
- The lead plates react with the sulfuric acid.
- This reaction releases electrons, which flow through the circuit as electricity.
- As the battery discharges, the lead plates are converted into lead sulfate, and the sulfuric acid becomes weaker (more diluted with water).
-
Charging (Reversing the Reaction):
- When an external voltage is applied to the battery (during charging), the chemical reaction is reversed.
- The lead sulfate is converted back into lead and sulfuric acid.
- This process restores the battery to its charged state.
In short, lead batteries work by converting chemical energy into electrical energy through a reversible chemical reaction involving lead and sulfuric acid.
