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. Cadmium. A metal used in about the shape of a pencil for obtaining voltage of positive or negative plates. It is dipped in the electrolyte but not allowed to come in contact with plates. Capacity. The number of ampere hours a battery can supply at a given rate of current flow after being fully charged, e.g., a battery may be capable of supplying 10 amperes of current for 8 hours before it is exhausted. Its capacity is 80 ampere hours at the 8 hours rate of current flow. It is necessary to state the rate of flow, since same battery if discharged at 20 amperes would not last for 4 hours but for a shorter period, say 3 hours. Hence, its capacity at the 3 hour rate would be 3x2O=60 ampere hours. Case. The containing box which holds the battery cells. Cell. The battery unit, consisting of an element complete with electrolyte, in its jar with cover. Charge. Passing direct current through a battery in the direction opposite to that of discharge, in order to put back the energy used on discharge. Charge Rate. The proper rate of current to use in charging a battery from an outside source. It is expressed in amperes and varies for different sized cells. Corrosion. The attack of metal parts by acid from the electrolyte; it is the result of lack of cleanliness. Cover. The rubber cover which closes each individual cell; it is flanged for sealing compound to insure an effective seal. Cycle. One charge and discharge. Density. Specific gravity.
