ii Observe
strictly the following instructions:
1. Mointoin the electrolyte level ot the level
of the perforoted
inserts between the plotes
or
so thot the inserts ore
covered with the electro-
lyte to o moximum height
of 4
mm. The
bottom
limit of the electrolyte level is 3 mm below the
perforoted inserts. Use only distilled woter for
topping up the electrolyte. Add electrolyte only
if it hos been obviously spilt from
the bottery.
In such cose, its density must correspond to
the density of the electrolyte Eemoining in the
bottery. 2. Keep the bottery terminols
cleon, remove
oxides occosionolly, ond
coot the terminols
with minerol
ielly.
3. Wipe off the electrolyte spilt
over the bot-
tery surfoce since it is conductlve ond couses
dischorging of the bottery.
4. Check the
chorging of the bottery occord-
ing to
the electrolyte density or check the
voltoge drop using o voltmeter with o looding
resistor ond comporing the obtoined reoding
with on evaluotion toble or scole.
5. When chorging the bottery
outside the cor,
use chorging current volues occording to the
toble. The voltoge should be
controlloble in the
ronge from 12.6 to 16.8
volts. The fully dis-
chorged bottery is fully chorged in obout 13 to
20 hours when
o) the electrolyte ottoins o density of 1.28 in
oll cells ond does not chonge in o period
of
two hours;
b) the cell voltoge (meosured
with opplied cur-
rent) ottoins o volue of 2.6
to 21
volts ond
does not chonge within two hours
of con-
tinued chorging;
c) oll cells ore lively gossing.
6. An olreody used bottery must not be left
without electrolyte or dischorged os it is opt to
suffer from
such o condition.
7. The bottery in on unused cor must
be
removed ond chorged outside the cor
within
three months ot th-e lotest. lf the cor is under
repoir for o prolonged
period,
toke oll necessory
steps to keep the bottery in good
condition.

Diffenent instructions, determined specificolly
by bottery monufocturers, opply to moking o
new ond empty bottery reody for
operotion or
to so-colled quick
chorging.
Sofety Precoutions ond Other Meosures
During chorging, the electrolyte temperoture
must not exceed +40oC. As soon os this
tem'
peroture is reoched, interrupt the chorging or
lower the chorging current (this
opplies es-
peciolly to so-colled quick
chorging).
During chorging, on explosive mixture of hy-
drogen with oxygen is liberoted from the elec-
trrolyte. Therefore, the oreo where the bottery is
chorged must be ventiloted, ond it is forbidden
to opprooch with o noked flome (or
spork) the
cell filling holes (even
ofter o consideroble
period of time ofter the chorging hos been
completed). When chorging the bottery, open the filling
holes of its cells to enhonce degossing.
The electrolyte is on ocid hormful to the skin
ond clothes os well os to ports
of the cor fin-
ished in
enomel. Rinse with woter immediotely
ony contominoted spots.
