| RR 239 (100 BKS.) (DB{Donald Bastow - Suspensions} 461-9-12 24) NP 200975 V7835P ROLLS-ROYCE, LTD. INSTRUCTIONS. To PETO & H.L. Order No. IC124 Customer's No. Re tests on P.R.B.D.H.11-2-4 Battery (185-C) On Low Rate Discharge through a constant external resistance of 1.80w 71 ampere hours were realised. All cells showed positive weakness. Following a full charge & High Rate Discharge through a constant external resistance of .1000w was taken Initial amperes = 108.5 Time to 104 " = 7.5 min. " " 100 " = 11.2 " " " 90 " = 16.2 " " " 80 " = 18.3 " All cells showed negative weakness. Signed S.G. This Sheet must be filed on completion of the work. | ||
