Interestingly, many battery manufacturers do not quote a value for the heat generated on discharge because lead acid batteries are considered as endothermic. However, manufacturers generally accept that the internal components and external connections all have a resistance and will generate heat when a current is flowing.

Lead Acid Battery Charging – The Formation of Key Elements
The typical lead-acid battery formula consists of lead dioxide (PbO2) as the positive plate and sponge lead (Pb) as the negative plate, immersed in a sulfuric acid (H2SO4) electrolyte. This setup is clearly depicted in a lead-acid battery diagram, which shows the arrangement of these components within the battery casing.
Lead-acid batteries are a type of rechargeable battery that uses lead and lead oxide electrodes submerged in an electrolyte solution of sulfuric acid and water. They are commonly used in vehicles, backup power supplies, and other applications that require a reliable and long-lasting source of energy.
