SUMMARY
The energy density of a fully charged 15.0 kg lead-acid battery is approximately 9.6 MJ/kg, based on its ability to deliver 1450 W for one hour. In comparison, gasoline has a heat of combustion of about 44 MJ/kg. This stark difference highlights the lower energy density of lead-acid batteries relative to gasoline, making them less efficient for energy storage in applications requiring high energy output.
