The battery was then again discharged as before a 65.3 ampere hours were obtained. This shows that a battery can be fully charged by this method although it has not reached its maximum PD. To confirm the above Exide TR {Capt. F. W. Turner - Finance} battery was fully charged at 6 amperes, the maximum sustained PD being 15.4 & discharged as before & 58.7 ampere hours were obtained. It was then charged up again on 17 volts the maximum sustained PD was 15.2 & the final charging current 6.5 amperes these remained constant for 3 hours Signed Tromp C-D This Sheet must be filed on completion of the work. | ||
