Customer's No. X 4617 S Re Tests on S1 Battery (154) This battery has been on our bench b/f test - for 22 months & in addition has run 18,206 miles on the road. On Low Rate Discharge through a constant external resistance of 1.80 w. 50 ampere hours were realised. All cells showed positive weakness. On High Rate Discharge through a constant external resistance of .100 w. Initial amperes = 102 Time to 100 " = 1.0 min " " 90 " = 6.0 " " " 80 " = 12.0 " All cells showed slight positive weakness. Signed: G.J. This Sheet must be filed on completion of the work. | ||
