How to Handle Battery
NKS000EU
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.
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.
●
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.
●
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
Never charge at more than 50 ampere rate.
NOTE:
The ammeter reading on your battery charger will automatically decrease as the battery charges. This indi-
cates that the voltage of the battery is increasing normally 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 cells varies more than 0.050, the battery should be
replaced.
Trouble Diagnoses with Battery/Starting/Charging System Tester (Battery)
NKS000EV
CAUTION:
When working with batteries, always wear appropriate eye protection.
NOTE:
●
To ensure a complete and thorough diagnosis, the battery, starter and generator test segments must be
done as a set from start to finish.
●
If battery surface charge is detected while testing, the tester will prompt you to turn on the headlamps to
remove the surface charge.
●
If necessary, the tester will prompt you to determine if the battery temperature is above or below 0
°
C (32
°
F). Choose the appropriate selection by pressing the up or down arrow button, then press “ENTER” to
make the selection.

1.
Turn off all loads on the vehicle electrical system. Clean or repair
as necessary.
2.
Visually inspect the battery, battery terminals and cable ends
with ignition switch in “OFF” position.
NOTE:
The contact surface between the battery terminals, cable ends
and tester leads must be clean for a valid test. A poor connec-
tion will prevent testing and a “CHECK CONNECTION” mes-
sage will appear during the test procedures. If this occurs, clean
the battery terminals, reconnect them and restart the test.
3.
Connect the red tester lead clamp to the positive battery termi-
nal, and the black to the negative terminal.
4.
The tester will turn on automatically. Using the arrow keys,
select “IN-VEHICLE” on the tester and then press the “ENTER”
key.
5.
Locate the battery type and rating stamped or written on the
top case of the battery to be tested.
NOTE:
The battery rating will have either of the following.
●
CCA: Cold Cranking Amps (490 CCA, 550 CCA, etc.)
●
JIS: Japanese Industrial Standard.
When using the battery tester: Use the CCA rating only.
●
The tester requires the CCA rating for the battery be entered
exactly as it is written or stamped on the battery.
●
U.S. market: Refer to the latest “Battery Testing” Technical
Service Bulletin (TSB) for a chart which contains these ratings
listed by vehicle.
●
You must not use the JIS rating.
6.
Using the arrow and “ENTER” keys alternately, select the battery type and rating.
NOTE:
The tester lists five choices; CCA, JIS, IEC, DIN, and EN. Use only the CCA choice .
7.
Press “ENTER” to begin the test. Diagnosis results are dis-
played on the tester. Refer to
.
