BATTERY INSPECTION
• Check the charge condition of the battery.
Periodically check the specific gravity of the electrolyte. Keep a
close check on charge condition to prevent over-discharge.
CHECKING ELECTROLYTE LEVEL
WARNING:
Never allow battery fluid to come in contact with skin, eyes, fabrics, or painted surfaces. After touch-
ing a battery, never touch or rub your eyes until you have thoroughly washed your hands. If acid con-
tacts eyes, skin or clothing, immediately flush with water for 15 minutes and seek medical attention.
Failure to do this may cause personal injury or damage to clothing or the painted surfaces.
• Remove the cell plug using a suitable tool.
• Add distilled water up to the MAX level.
Sulphation
A battery will be completely discharged if it is left unattended
for a long time and the specific gravity will become less than
1.100. This may result in sulphation on the cell plates.
To determine if a battery has been “sulphated”, note its voltage
and current when charging it. As shown in the figure, less cur-
rent and higher voltage are observed in the initial stage of
charging sulphated batteries.
A sulphated battery may sometimes be brought back into ser-
vice by means of a long, slow charge, 12 hours or more, fol-
lowed by a battery capacity test.
SPECIFIC GRAVITY CHECK
1.
Read hydrometer and thermometer indications at eye level.
2.
Convert into specific gravity at 20
°
C (68
°
F).
Example:
• When electrolyte temperature is 35
°
C (95
°
F) and specific gravity of
electrolyte is 1.230, converted specific gravity at 20
°
C (68
°
F) is
1.240.
• When electrolyte temperature is 0
°
C (32
°
F) and specific gravity of
electrolyte is 1.210, converted specific gravity at 20
°
C (68
°
F) is
1.196.

3.
Check that battery fluid level is between MAX and MIN. If the battery fluid level is outside the specified
level, add fluid to satisfy the specified level.
Are these inspection results normal?
YES-1 (Test using battery checker)>>GO TO 2.
YES-2 (Test using load tester)>>GO TO 5.
NO
>> Replace battery.
2.
CAPACITY TEST
Test using battery checker.
Is the inspection result normal?
YES-1 (OK)>>Ready for use. Mount battery again and check loose terminals. Also check other related cir-
cuits.
YES-2 (Slight discharge)>>GO TO 3.
NO-1 (Large discharge)>>GO TO 4.
NO-2 (NG)>>Replace battery.
3.
HALF CHARGE
1.
Perform half charge, according to the following table.
2.
Test using battery checker.
Is the inspection result normal?
YES (OK)>>Ready for use.
NO (Other than OK)>>Replace battery.
4.
FULL CHARGE
1.
Perform full charge, according to the following table.
2.
Test using battery checker.
Is the inspection result normal?
YES (OK)>>Ready for use.
NO (Other than OK)>>Replace battery.
5.
CHECKING SPECIFIC GRAVITY
Check specific gravity. Refer to
PG-121, "EXCEPT FOR R9M : How to Handle Battery"
.
Inspection results
Above 1.220>>GO TO 6.
1.100 - 1.220 (When performing quick charge)>>GO TO 8.
1.100 - 1.220 (When performing standard charge)>>GO TO 11.
Below 1.100>>GO TO 12.
6.
