A general knowledge of batteries includes the method of construction and the materials used in the manufacture of batteries. Chemistry deals with the actions producing electricity and aids in determining the reasons and remedy for trouble. The expert must know what happens in a battery standing idle, just what takes place in the charging and discharging, and what determines the capacity of batteries. A knowledge of battery diseases will help a man very materially in the proper diagnosis of battery trouble.
The shop work of the battery man includes caring for, charging, lead burning, and rebuilding batteries. Caring for batteries includes keeping the plates covered with distilled water, brushing dirt and dust from the top, keeping cables and connections tight, cleaning battery terminals and connections and carefully inspecting and testing it frequently. Charging consists, figuratively, in feeding it electricity, which when digested gives it energy. It is necessary for the battery man to be thoroughly familiar with the charging apparatus and able to operate it successfully. Lead burning is a process of melting together the plates and straps or posts and top connectors and terminals with a special lead-burning outfit. In rebuilding a battery, it is first charged, then opened and torn down, after which the plates are repaired or replaced, assembled with the proper separators, replaced in the jars, and then carried through the charging process. The covers are next put on and sealed.
Tools and Equipment
The room for battery work should have a floor such as tile or brick, not easily affected by acid. The equipment ordinarily includes work benches, vises, a lead burning outfit, water supply, charging benches and equipment, shelves, and stoves. Proper tools, including brushes, scrapers, pliers, nippers, files, hydrometers, putty knife, wrenches, brace and bit, stock drills, center punches, hack saws, kettles, ladles, jars, screw drivers, materials and other hand tools are provided. The work is practically all hand work and consequently requires hand tools.
Disabilities
Battery work requires the use of two hands. The loss of three fingers from one hand would not seriously impair efficiency if some grip with the remaining finger and thumb is retained. In the use of pliers, screw drivers, brace and bits, and other tools it is necessary to hold them firmly. Hearing is not particularly essential, but good eyesight is necessary. Stooping, bending, and lifting the weight of a battery would not affect men with slight hernia and abdominal trouble. A man with artificial legs should be able to do the work if he can get around without great difficulty.
Danger from lead poisoning and acid burns and fumes is prevalent in battery work, but occurs only through carelessness. A man with any skin or lung diseases or wounds probably should not undertake this work. Gloves are worn in handling lead, but they will not protect against skin wounds. The eyes may be injured by lead and acid, but by wearing goggles this can be avoided. A man with any open wounds should not enter battery service work.
Special Appliances
No special appliances can be arranged satisfactorily to handle the tools and equipment, although stools can be provided for the man who is required to sit.
