MAINTENANCE
(33) Check battery condition: clean and grease connections
With battery
in
location
I. Check battery and surrounding area for corrosion
from battery chemicals.
2. Clean
off
any cprrosion found.
3. Check visually for cracks
in
battery case.
4. Report any
case
cracks found.
5. Check security
of
terminal connections.
6. Coat terminals with petroleum jelly.
For each cell

7.
Check
electrolyte specific gravity, using
an
hydrometer, which
if
correct
will
approximate to the
tabled readings below.
NOTE
(a) Do
NOT
check S.G. immediately after adding
distilled water
as
a
false
reading may be obtained.
(b)
S.G. readings approximately equal for each
cell
Indicate a battery in good condition. Conversely,
it'
one
or
more cells show a reading lower than the
others the battery
is
approaching the end
of
its useful
life.

8. Check voltage,using a heavy discharge tester, which if
correct will
give
approximately. equal readings for
each cell.
CAUTION: This check should
NOT
be
made on a
battery in a low state
of
charge
as
shown by
procedure 7
as
damage to the battery can result.
NOTE(
a)Before making this check on a battery that

should be switched on for 2 or 3 minutes to remove
any
surface
