RR 238 (150 BKS.) (DB{Donald Bastow - Suspensions} 431-8 12 24) MP 306975 ROLLS-ROYCE, LTD. INSTRUCTIONS. To: E.F.b. Order No.: J.C.6. Customer's No.: Re terminal P.D.s. of Std. P&R Batteries. The terminal P.D.s. were taken on 20HP & 40/50HP P&R batteries when charging at different currents as follows. Amperes | 20HP TBD7-10 | 40/50HP RR11-2 9 | 2.91 | 2.80 | .11 12 | 2.95 | 2.83 | .12 14 | 2.99 | 2.86 | .13 Only one reading is given because all the cells were the same. Signed G.F.
