| X5840 He/Rm.{William Robotham - Chief Engineer} from EFC. CFOA/AD28.2.30. 20 HP. DYNAMO OUTPUT ON 14-GIV. Answering your He/Rm{William Robotham - Chief Engineer}3/WJ27.2.30. the high output of this dynamo will not harm the battery so long as the battery is not too near its top state of charge, but when the battery commences to gas seriously it is harmful if the charge is subsequently continued for periods say exceeding 15 minutes, owing to the rise of temperature of the battery thereby caused and the danger of exceeding the maximum permissible temperature of the electrolite namely 110°F.{Mr Friese} EFC.
