How to Handle BatteryINFOID:0000000006288754
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.
METHODS OF PREVENTING OVER-DISCHARGE
The following precautions must be taken to prevent over-discharging 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 battery cable from the negative terminal. (If
the vehicle has an extended storage switch, turn it off.)
 Check the charge condition of the battery. Periodically check the specific gr avity 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, imme diately flush with water for 15 minutes and seek medical attention.

BATTERY INSPECTION
 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. Use the chart below to correct your hydrometer reading accord- ing to electrolyte temperature.

CHARGING THE BATTERY
CAUTION:
 Never “quick charge” a fully discharged battery.
 Keep the battery away from open
flame while it is being charged.
 When connecting the charger, connect the leads first, then turn on the charger. Never turn on the
charger first, as this may cause a spark.
 If battery electrolyte temperature rises above 55 °C (131 °F), stop charging. Always charge battery at
a temperature below 55 °C (131 °F).
Charging Rates
Do not charge at more than 50 ampere rate.
NOTE:
The ammeter reading on your battery charger will automat ically decrease as the battery charges. This indi-
cates that the voltage of the battery is increasing norma lly as the state of charge improves. The charging amps
indicated above refer to initial charge rate.
 If, after charging, the specific gravity of any two ce lls varies more than 0.050, the battery should be replaced.

TROUBLE DIAGNOSIS WITH BATTERY SERVICE CENTER
For battery testing, use Battery Service Center (J-48087) . For details and operating instructions, refer to Tech-
nical Service Bulletin and/or Battery Service Center User Guide.
