II To:___________________ 19_______ Order No. J.C.30 Customer's No.____________ weakness on the cadmium. After a further full charge the battery was High Rate Discharged through an invariable external resistance of .100 w Initial amperes = 100.8 Time to 100 " = 2.9 min " " 90 " = 15.1 " " " 80 " = 18.2 " This test is not so good as one previously taken. The Fuller cell was down first, followed closely by the Oldham. The Exide & P&R cells were all the same, & all cells showed negative weakness except the Fuller which showed positive weakness. By this it seems that the Fuller cell will be the first to fail. Signed J.S. This Sheet must be filed on completion of the work. | ||
