Customer's No. X4617E Re Tests on Exide 6RR5-3 Battery (174) This battery was removed from the m {Mr Moon / Mr Moore} /s. for bench tests. On low rate discharge through a constant external resistance of 1.30w 81.0 ampere hours were obtained, the cells showing positive weakness on the Cadmium. On high rate discharge through a constant external resistance of .100w Initial amperes = 106.0 Time to 1.0v " = 5.2 min " " 1.00 " = 13.5 " " " .90 " = - " " .80 " = - All cells showed negative weakness on the Cadmium. Signed: G.J. This Sheet must be filed on completion of the work. | ||
