Abstract
The life expectancy of nickel-cadmium (NiCd) and mercury (7439976) (Hg) batteries used in coal mine dust personal sampling units (CMDPSUs) and charcoal tube pumps is reviewed. General characteristics of Ni/Cd batteries including discharging, recharging, and ability to function at elevated temperatures are discussed. The characteristics of the CMDPSUs and the charcoal tube pumps are also discussed. Life expectancy estimates are provided for seven commercial battery packs based on information provided by the manufacturers. Estimates include the mean number of cycles between failures at different temperature. The authors conclude that all of the tested battery packs are satisfactory.
