land YOU know that acid mixture Is
needed instead Of water alone, then
this can be prepared by simply mixing
water and chemically pure sulphuric
acid i'm the proportions of two parts
acid to five parts water by volume.
That is. for the average size of bat
{ terry. there should be measured out
five quarts OF water this being put I'M
Ian earth,nwSre vessel or other re-
Iccpttrle which would not be attacked
| bv the strong acid Then TO this
| pure water. two quarts Of su,phurlc
| should he very slowly added, stirring
1.-THE mixture well as the mixing pro-
cess Is carried ON. Special note
Ishould be taken Of the fact that the
| acid should be poured into the wa
| ter. and not the water into the acid
| This is because there would he eN-
| Ccssive evaporation OF the water due
| to overheatiug b.. should the water be
| pOured into the acid.
| A mixture in these proportions Will
| strangely. give only about six and one
half quarts Of eIectroIyte on the av-
erage. although you would expect
seven quarts of solution. The discrep-
] anCy is in the evaporation OllQe va
/ ter and the extent Of it depends
| largely ON the rate at which the two
were mixed. As the specific gravity
of chemically pure sulphurtc acid is
about 1.S4O, and that of water is
! 600. the gravity Of the resulting
mixture should be in the neighbor-
( hood OF 1909 when the solution Of
acid in water has become cool
/ Corrosion is an enemy Of the stor-
lage battery. If the terminals show
any signs Of it. the matter should be
removed from them as soon as posi-
! BILE before the lead parts are eaten
iaway. The best way TO clean the ter
|mnaIs and connections - TO take or
AN the parts. such as bolts, uurs
straps. etc., that can be removed
without damaging the battery, and
then to immcrse them i'm solution or
soda and water. Use a good prOpOr-
ton Of soda. so that there will bo
plenty Of action. and allow tine pieces
10 stand in the solution for about one
hour. After that they should be
claned with stiff brush until there
are no signs of the corrosion
IT is rather unusual. but petroleum
IeIlv is now useful i'm this connection.
Having cleaned the terminals to your
satisfaction - not only thoroughly
| brushing the parts that you can take
off. but brushing the lead terminal
ends and conncctors that cannot be
