CAUTION:
If it becomes necessary to start the engine with a booster bat-
tery and jumper cables,
a. Use a 12-volt booster battery.
b. After connecting battery cables, ensure that they are
tightly clamped to battery terminals for good contact.
c. Never add distilled water through the hole used to check
speci®c gravity.
How to Handle Battery
METHODS OF PREVENTING OVER-DISCHARGE
The following precautions must be taken to prevent over-discharg-
ing a battery.
+The battery surface (particularly its top) should always be kept
clean and dry.
+The terminal connections should be clean and tight.
+At every routine maintenance, check the electrolyte level.
This also applies to batteries designated as «low maintenance»
and «maintenance-free».
+When the vehicle is not going to be used over a long period of
time, disconnect the negative battery terminal.
+Check the charge condition of the battery.
Periodically check the speci®c gravity of the electrolyte. Keep
a close check on charge condition to prevent over-discharge.
CHECKING ELECTROLYTE LEVEL
WARNING:
Do not allow battery ¯uid to come in contact with skin, eyes,
fabrics, or painted surfaces. After touching a battery, do not
touch or rub your eyes until you have thoroughly washed your
hands. If acid contacts eyes, skin or clothing, immediately
¯ush with water for 15 minutes and seek medical attention.

+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 speci®c 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 volt-
age and current when charging it. As shown in the ®gure, less
current 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 speci®c gravity at 20ÉC (68ÉF).
Example:
+When electrolyte temperature is 35ÉC (95ÉF) and speci®c grav-
ity of electrolyte is 1.230, converted speci®c gravity at 20ÉC
(68ÉF) is 1.240.
+When electrolyte temperature is 0ÉC (32ÉF) and speci®c grav-
ity of electrolyte is 1.210, converted speci®c gravity at 20ÉC
(68ÉF) is 1.196.
