Ing and lightning system, the stor-
age battery has become an extremely
important uni: of the automobile. and
IL Is one which needs certain amount
OF attention. The work IL does Is
tremendous in comparison 10 its Size.
while the enormous sale OF autos IN
the last few years can lie assigned 10
II perhaps more than 10 any other
feature.
told YOU in an carly lesson that a
battery is composed of cells. thus
:, dry battery : composed OF two or
more dry cells, and a storage battery
of TWO or more storage cells. or, as
they are also called, accumulator
cells. and sometimes secondary cells.
Each accumulator coll. no. matter
how small or how large. Will yield II
current having vintage electrical
prcssurol OF very slightly over two
volts. The cell will give almost tho
iiIll voltage even though II be nearly
discharged.
OF course. two volts Is not enough
pressure for practical purposes. We
must have six or moro volts. In or
der TO set the increased voltage. a
number II cells are connected toCeth-
cr in Series" that IS. the positive pole
tive pole Of the next cell. and so on.
Thus II = SiX-volt battery is required.
three cells arc so connected up, while
II twclvc-volt battery is required.
six cells arc used.
In many cars the l2-volt battery is
used for The starting motor. but only
and ignition. In this case a separate
''cu'-in' : made, so as TO use only
ih:ic cells for the lights, etc. The H.
1ustration shows this, the hcavy wires
volts.
The capacity or lot us say the
amount Of current which can be
given i'm amperc-hours. Thus. there
are 40, Go. So 100 etc. ampcre- hour
batteries, The number Of amperes
flowing, MULTIPLIED by the number OF
hours howS, being the ampcre
can yield ampcrc for GO hours. or .
LmpercS for 80 hours. or 10 ampcrcs
Tor hours or 10 ampere for -
