How to Handle Battery

INFOID:0000000005516884

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 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.

BATTERY

• 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.
