Alloy. As used in battery practice, a homogeneous combination of lead and antimony.
Alternating Current. Electric current which does not flow in one direction only, like direct current, but rapidly reverses its direction or "alternates" in polarity so that it will not charge a battery.
Ampere. The unit of measure of the rate of flow of electric current.
Ampere Hour. The product resulting from multiplication of amperes flowing by time of flow in hours, e.g., a battery supplying 10 amperes for 8 hours gives 80 ampere hours. See note under "Volt?" for more complete explanation of current flow.
Battery. Two or more electrical cells, electrically connected so that combination furnishes current as a unit.
Battery Terminals. Devices attached to the positive post of one end cell and the negative of the other, by means of which the battery is connected to the car circuit.
Bridge (or Rib). Wedge-shaped vertical projection from bottom of rubber jar on which plates rest and by which they are supported.
Buckling. Warping or bending of the battery plates.
Burning. A term used to describe the operation of joining two pieces of lead by melting them at practically the same instant so they may run together as one continuous piece. Usually done with mixture of oxygen and hydrogen or acetylene gases, hydrogen and compressed air, or oxygen and illuminating gas.
Burning Strip. A convenient form of lead, in strips, for filling up the joint in making burned connections.
