Charging of 40/50 Batteries. A comparison of several 40/50 batteries has been made to find the effects of the increase of internal resistance whilst fully charged (gassing) and charging. Dynamo AV was used (with control brush set at 120°) and was connected up through standard chassis wiring, distribution board and ammeter at first to the reservoir battery until fully hot and then to the several batteries to be tested which were already (Contd) Signed This Sheet must be filed on completion of the work | ||
