| ROLLS-ROYCE LTD. INSTRUCTIONS. To: B.T.L. Order No.: IC49 Customer's No.: X4617S Re tests on SJ Battery (172) This Battery was removed from 9EX for bench tests, & on a low rate discharge being taken through an invariable external resistance of 1.80w on 39.6 ampere hours were realised. All cells shewed positive weakness on the badmium & all had an equal capacity both the Fuller & Oldham cells. After a full charge, it was given a high rate discharge through an invariable external resistance of .100 w & the Initial amperes = 99.0 Time to 90 " = 6.7 min " " 80 " = 9.5 " Signed: (cont'd) This Sheet must be filed on completion of the work. | ||
