| Contd. -2- EFC1/S1.1.21. On the 10 ampere rate of discharge the voltage started at 12.9 and fell to 10.0 in 5¾ hours giving 57.5 ampere hours. Continuing the discharge to 6.0 volts, 63.5 ampere hours were obtained, the time of course being 6.5 hours. The above results are for a battery of 10 cells. EFC. | ||
