Three hundred twenty zinc-air batteries representing four manufacturers (Energizer, Power One, Duracell, and Ray-O-Vac) and four cell sizes (10, 312, 13, and 675) were exposed in a salt spray fog apparatus for 2.5, 5.5, 24, 48, and 72 hours. At the conclusion of each exposure, the batteries were rated blindly for the presence of rust by four experienced audiologists using a four point rating scale. Results revealed significant differences in the rating of rust across the four manufacturers and… CONTINUE READING
