L.F.G. J.D.18. X4617S. 22-7-29 X4617S. Re Tests on SU & SV Batteries (178-7). On Low Rate Discharge through a constant external resistance of 1.80w these batteries gave 34.8 ampere hours. All cells shewed positive weakness. The P&R cell in SV had a very poor capacity. After a full charge a High Rate Discharge was then taken. Initial amperes = 100.0 Time to 90 " = 3.2 min. " " 80 " = 5.5 " All cells shewed negative weakness. The P&R in SV again gave poor result. SV Battery has been on our bench life test 40 months. SU Battery has been on our bench life test 32 months & has run 5,595 miles. H.J. | ||
