About 60% of the weight of an automotive-type lead–acid battery rated around 60 A·h is lead or internal parts made of lead; the balance is electrolyte, separators, and the case. [8] For example, there are approximately 8.7 kilograms (19 lb) of lead in a typical 14.5-kilogram (32 lb) battery.

While they offer proven safety, lead-acid batteries have a lower specific energy compared to lithium-ion types. In contrast, hybrid electric vehicles often use nickel-metal hydride (NiMH) batteries because of their long lifespan and ability to undergo many charge/discharge cycles. What is a lead acid car battery?
Typical (daily) charging: 14.2 V to 14.5 V (depending on manufacturer's recommendation) Equalization charging (for flooded lead acids): 15 V for no more than 2 hours. Battery temperature must be monitored. The lead-acid cell (usually part of a battery) also works on the principal of redox reactions.
Typical parameters for a Lead Acid Car Battery include a specific energy range of 33–42 Wh/kg and an energy density of 60–110 Wh/L. The specific power of these batteries is around 180 W/kg, and their charge/discharge efficiency varies from 50% to 95%.
Conventional vehicles typically rely on Lead Acid Car Battery due to their high power output and affordability. These batteries use water-based electrolytes and have individual cell voltages that are relatively low. While they offer proven safety, lead-acid batteries have a lower specific energy compared to lithium-ion types.
A typical lead–acid battery contains a mixture with varying concentrations of water and acid. Sulfuric acid has a higher density than water, which causes the acid formed at the plates during charging to flow downward and collect at the bottom of the battery.
