Americans purchase nearly 3 billion dry-cell batteries every year to power radios, toys, cellular phones, watches, laptop computers, and portable power tools.
Inside a battery, heavy metals react with chemical electrolyte to produce the battery’s power.
Wet-cell batteries, which contain a liquid electrolyte, commonly power automobiles, boats, or motorcycles.
Nearly 99 million wet-cell lead-acid car batteries are manufactured each year.
A car battery contains 18 pounds of lead and one pound of sulfuric acid.
