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
