STORAGE BATTERY ROOM. generators, engines and other centralstation machines, give no audible signsOf trouble and almost no visible will continue to deliver currentuntil severely injured. If the operatorin charge of the station will rememberthai a storage battery will do so much,and no more, in a given time, that theydeserve as careful treatment as a gen-erator unit, and that any attempt tomake them do more than they are de-signed for will only result in trouble,expense and dissatisfaction, then thestorage battery will prove itself a veryvaluable asset to the equipment of thestation, CHARGE. The rate at which the battery is tobe charged is usually specified by thecompany furnishing the battery. Thevoltage necessary to start the charge isabout volts per cell. If this doesnol give the required charging current,the voltage must be increased until theproper current value is
