CAUTION:
If it becomes necessary to start the engine with a
booster battery and jumper cables, use a 12-volt booster
battery.
After connecting battery cables, ensure that they are
tightly clamped to battery terminals for good contact.
Never add distilled water through the hole used to check
specific gravity.
How to Handle Battery
METHODS OF PREVENTING OVER-DISCHARGE
The following precautions must be taken to prevent over-dis-
charging 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.
When the vehicle is not going to be used over a long period
of time, disconnect the negative battery terminal. (If the
vehicle has an extended storage switch, turn it off.)
Check the charge condition of the battery.
Periodically check the specific gravity of the electrolyte. Keep
a close check on charge condition to prevent overdischarge.
CHECKING ELECTROLYTE LEVEL
WARNING:
Do not allow battery fluid 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 the acid contacts the eyes, skin or clothing,
immediately flush with water for 15 minutes and seek medi-
cal 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 specific gravity becomes less than 1.100.
This may result in sulphation on the cell plates.
To find if a discharged battery has been“sulphated”, pay atten-
tion to its voltage and current when charging it. As shown in the
figure at left, if the battery has been“sulphated”, less current and
higher voltage may be observed in the initial stage of charging.
SPECIFIC GRAVITY CHECK
1. Read hydrometer and thermometer indications at eye level.
When electrolyte level is low, tilt battery case for easy mea-
surement.

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.
