| Report contd. FHR 6/c25613 Variation of Voltage charging Edison 12 Volts. * 11.8. Volts at the commencement of charge 16.6. " finish of charge with charge on = 4.8. Volts variation on 16.6 Volts. = 28.9% Exides 4 Volts. * 4.0 Volts at the commencement of charge 5.6 " finish of charge with charge on = 1.6 Volts variation on 5.6V = 28.9% * These cells are discharged to 10.8V and 3.6V respectively but always rise again when left standing for a short time. This is more pronounced in the Edison. Hallis 2 | ||
