Beginner''s Guide: What Is a Lead-Acid Battery and What Does It …
Batteries used in cars are lead-acid batteries. They produce voltage by having plates of metal (made of lead-based alloys) immersed in an electrolyte solution (a mix of 65% water and 35% sulphuric acid) in six cells. A chemical reaction between the plates produces a voltage of approximately 2.1volts per cell, so a total of 12.6 volts.

Lead-Acid Batteries
The reaction of lead and lead oxide with the sulfuric acid electrolyte produces a voltage. The supplying of energy to and external resistance discharges the battery. HyperPhysics ***** Electricity and Magnetism. The discharge reaction can be reversed by applying a voltage from a charging source. HyperPhysics ***** Electricity and Magnetism.
How Lead Acid Batteries Work
The electrons enter the negative terminal and re-join with the lead sulphate, releasing the sulphate into the electrolyte to leave just lead on the negative plate. The sulphate ions enter the electrolyte and combined with the hydrogen ions to release the oxygen ions, and so the electrolyte acid becomes stronger.
How to make Lead Acid Battery at Home and Required Tools explained …
Making Electrolyte for the Lead Acid Battery: Add water to the Sulfuric acid; be very careful while making the electrolyte for the battery, after adding the water wait at least 30 minutes, so that the electrolyte can get cool. Finally, you can use the Hydrometer to check the specific gravity of the electrolyte.
Lithium Ion vs Lead Acid Battery
The energy density of lithium-ion batteries falls under the range 125-600+ Wh/L whereas, for lead acid batteries, it is 50-90 Wh/L. This drastic variation is due to the fact that lead acid batteries are much heavier than lithium-ion batteries, which in turn results in less energy density.

0.216–0.252 MJ/kg. lead–acid cell. 0.120–0.160 MJ/kg. Specific Volume (SV) Specific volume, on the other hand, is the energy stored per liter of volume or, to put it another way, the energy per cubic decimeter of space. Again using a lead–acid battery example, the SV might be 0.331 MJ/L.
What is the Role of the Separator in the Lead Acid Battery? (Explained)
The separator in a lead acid battery serves two primary purposes. First, it keeps the positive and negative electrodes from coming into contact with each other, which would cause a short circuit. Second, it allows ions to flow between the electrodes while preventing electrons from flowing through the electrolyte.

About the Lead Acid Battery | Battery Council International
Lead batteries operate in a constant process of charge and discharge When a battery is connected to a load that needs electricity, such as a starter in a car, current flows from the battery and the battery then begins to discharge. As a battery begins to discharge, the lead plates become more alike, the acid becomes weaker and the voltage drops.
