Order No. IC 58 Customer's No. X4617E Re Tests on baccle GRR5+-3 (174) This battery has been removed from the M.S. for bench tests to be taken. On low rate discharge through an invariable external resistance of 1.30w. 74.5 ampere hours were realised. All cells showed negative weakness on the cadmium test. Following a high rate discharge a full charge, a high rate discharge through an invariable external resistance of .100w was taken. Initial amperes = 111.0 Time to 1.04v = 13.8 mins " " 1.00v = 19.0 " These results are a great improvement on the previous tests made which were considered poor. Signed G.G. This Sheet must be filed on completion of the work. | ||
