Re Bench Tests of Exide 6RRS/1/2 Battery. This battery was taken out of the M.S. for bench tests, the results of which are as follows. High Rate Discharge through an invariable external resistance of .100Ω Initial amperes = 108.0 Time to 104 amperes = 9.6 mins " " 100 " = 17.3 " " " 90 " = 30.5 " " " 80 " = 33.3 " After a further charge this battery was given a Low Rate Discharge through an invariable external resistance of 1.80Ω & the ampere-hours realised were 81.6. These results are very much similar (cont'd) Signed: This Sheet must be filed on completion of the work | ||
