lcnce you have your "B" battery in.
Iled in your set and properly hooked
vou will not have to bother much
sut Il so long as the electricity that
.ives seems to have plenty Of kick"
lt.
when the electricity ceases to be
ooe enough there is only one thing
do-throw the battery away and
a new one.
ia fortunately, though the plate Of your
T. i,on bnlb requires q powerful current,
d s.ss very little of Il and good "B"
ttery ought to last you for six months
y !! rSs r,siI storage battery, however, is a
AZ different proposition. Here we
~ + niece. OF chemical mechanism
'ich AZ called upon to, deliver. quite q
snv current, to give q good deal Of
and to, give. It steadily IN . long
t.'' TSs dry cell is not fitted for this
.x.nuous work and, while four dry
l~ils hooked together will give you fairly
sstisfactory service" in lighting your
lament for short time, they very soon
sssch a point where the service becomes
r.st 80 nndependable. Though there may
rood deal Of life left in them, 1t
not the kind of life that will do for
1his purpose.
nake 81. 80, and doubt IL they would
Tst more than a week with any
S6ciency left at the end Of that time. It
~ould not take many weeks at this rate
\ ebyer the cost of first class storage
attery.
with the storage battery you will
Asve three very great advantages. First.
Az current you will draw from it will
4 steady and just the kind Of a cur
;rnt YOU want for radio purposes sec
!sud. il will stand up efficiently many
fines as long as the dry cell; third.
.shen the charge is exhausted 1t is an
.sseIpensiye matter to have n new charge
Xnt into it or put one in yourself by
hooking it up with your house lighting
current with the propef apparatus in
between and it is ready to begin all over
. storage battery requires looking
after Just as does any other delicate
lnd efficient piece of mechanism.
First, there are certain things you
must be careful of In order to cover the
Teouircments of the fire underwriters.
They have decreed that the battery
must be completely housed SO that all
NE parts are covered. They also de.
nand that you connect the battery to
your wires through fuses which will not
3low more than ten amperes to pass.
This is done so that If two wires come
accidentally in contact the fuse will
Allow out and the current will be stopped
before it has chance to start a fire.
They also have ruled that storage bat
terits which have exposed terminals
must be provided with a ventilated
cover Of such a nature that It will pre-
vent accidental short circuit across the
3erminals. They insist that the wiring
between the storage battery and yonr
;{ldio apparatus be not less than No.
" B & S gauge approved rubber
covered.
The underwriters say nothing about
your eyes and your clothes, but let me
warn you not to spill the acid of the
battery upon the carpet nor let any pary
9f the battery, which Is moist with this
Acid, touch your clothes. I once had
man carry storage battery a short
distance for me without warning him
q It and about an nour afterward the
Cloth Of his trouser legs. against which
Il had rubbed, simply fell to pieces.
And above all, after handling any
patt Of the battery, do not touch your
YES. do not know that this acid
you'd cause blindness, but ! do know
shat it can cause most uncomfortable
paln.; 4
Never have fame near the top Of .
freshly charged battery. During the
process Of charging and for some time
Gterward the solution forms a gas
which Is highly explosive.
Examine your battery through the
aIler.caps at least once week and SEQ
1at the solution is we'll above the
egges OF the plates. If 1t is not, pour In
ebtllled water or chemically pure
xeter that you can get from the drug
fore, until the plates are we'll covered.
Y the solution becomes weak 1t Is much
petter to let man in charge Of the
rsular battery station do tho refilling
ps you rather than attempt it your.
There arc many makes of "home
nmsrsers' on the market now, all de.
lsned to change the alternating cur.
