Jul 25, 2019nbsp018332nickel cadmium or nicad while not as common as lead-acid, the nickel-cadmium battery, or nicad, is best for its ability to operate through a high-temperature range.It has a higher life span and fewer maintenance requirements.Also, nicad batteries initially cost more than lead-acid and include cadmium, a potentially hazardous material.
