Customer's No. X 46175 Re Tests on SU & SV Batteries (176 & 177) The above two batteries were put on bench tests the results of which are as follows. SU on Low Rate Discharge through a constant external resistance of 1.80w gave 23.1 ampere hours. SV on a similar discharge gave 38.2 ampere hours. All the cells shewed positive weakness on the cadmium. The batteries were fully charged & given a High Rate Discharge through a constant external resistance of .100w. SU. Initial amperes = 101.2 amperes Time to 100" = 2.0 mins " " 90" = 6.5 " " " 80" = 7.4 " Signed (cont'd) This Sheet must be filed on completion of the work. | ||
