| Cold
Cranking Ampere (CCA): Cold Cranking Amps is a rating used in the
battery industry to define a battery's ability to start an engine in
cold temperatures. |
| –
| The
rating is the number of amps a new, fully charged battery can deliver
at -18 °C(-0.4 °F) for 30 seconds, while maintaining a voltage of at
least 7.2 volts for a 12 volt battery. |
| –
| The higher the CCA rating, the greater the starting power of the battery. |
| •
| RESERVE
CAPACITY (RC) : Reserve Capacity is a battery industry rating, defining
a battery's ability to power a vehicle with an inoperative alternator
or fan belt. |
| –
| The
rating is the number of minutes a battery at 26.7 °C(80 °F) can be
discharged at 25 amps and maintain a voltage of 10.5 volts for a 12 volt
battery. |
| –
| The higher the reserve rating, the longer your vehicle can operate should your alternator or fan belt fails. |

| [AGM Battery for ISG System] |
AGM
battery is used for especially heavy load on the vehicle network
depending on equipment and requirements. AGM stands for Absorbent Glass
Material Battery, which is absorbent glass fibre fleece. AGM batteries
are fitted to models with high electrical loads or for consumer with
high energy demand.
The constantly increasing energy demand of modern vehicle electrical systems calls for ever more powerful battery solutions.
The power consumption is considerably high even when the vehicle is partked.
The somewhat higher price compared with a battery of similar size is fully balanced by the following benefits:
| –
| Significantly longer service life |
| –
| Increased starting reliability at low temperatures |
| –
| 100% free from maintenance |
| –
| Low risk in the event of an accident (reduced risk to the environment) |
Recharging the AGM battery
The battery can be charged by using a battery charger with a constant charging voltage of 14.8 V.
If possible, keep the battery temperature between 20°C (68°F) and 30°C (86°F) during charging.
Only chargers with voltage clamping (IU or WU curve) or chargers with IUoU curve capable of trickle charge can be used.
IU or WU charging technique
Optimized charging voltage for IU or WU: 14.7 V (at 20°C - 30°C (68°F - 86°F)) for about 24 hours Min. charging voltage at 20°C (68°F): 14.4 V Max. charging voltage at 20°C (68°F): 14.8 V 10% of capacity is recommended as charging current (e.g. 60 Ah : 10 = 6.0 A charging current). |
| •
| Do not charge an AGM battery with voltage greater than 15.2 V. Do not quick charge the AGM battery. |
|
| •
| If
the battery is charged directly at the battery terminals on vehicles
with battery sensor, misinterpretations of battery condition may occur,
and under certain circumstances, unwanted 'Check Control' message or
faulty memory can be prompted. When recharging is finished, let the battery stand for over 10 hours at normal temperature for battery stabilization. |
|

|
| •
| ISG
(Idle stop & go) system equipped vehicle uses the AGM battery only.
Installing a flooded battery may potentially lead to engine electrical
trouble or ISG system error. |
| •
| Replace with an AGM battery of the same capacity. |
|
| •
| Ensure that an AGM battery is fitted. |
| •
| In all cases, an AGM battery must be installed and registered in the vehicle for the ISG function to work perfectly. |
| •
| After
replacing with a new battery, the vehicle must stand for at least 4
hours with the ignition switch OFF, doors closed and hood switch OFF. |
| •
| ISG system stabilization may take 4 hours after installing a new battery. |
| •
| After standing for 4 hours, the ISG function will operate with 2 cranks by the user. However,
for the first 25 times, the ISG function can operate regardless of ISG
system stability for ISG function operation check. |
|
| •
| Do not open the AGM battery. The
AGM battery must not be opened under any circumstances as the
introduction of oxygen from the air will cause the battery to lose its
chemical equilibrium and become non-operational. |
|
|
Electrolyte Level Inspection (MF Openable Battery only)
| 1. | Check that the electrolyte level lies between the “UPPER” and the “LOWER” lines.
 |
| 2. | If the electrolyte level is below the "LOWER" line, add water until the level of electrolyte comes up to the "UPPER" level. | (1) | Remove
the cell caps (A) and then carefully add distilled or purified water to
bring the level of electrolyte in each cell to the "UPPER" line. |
| (2) | Put the cell caps back on the battery. |
| (3) | Charge the battery to mix the water and residual acid in the battery. | •
| Never
use the water with impurities or additives to fill the battery cells.
It will reduce the life and performance of the battery. |
| •
|
Do not overfill the battery cells. It may result in an "overflow" of
the acid electrolyte and cause corrosion on adjacent metal parts,
performance deterioration and shortening the life span. |
| •
| Make sure the cell caps are installed securely before charging the battery after filling the battery cells. |
|
 |
|
Battery charging
In general, vehicle battery charging system has three forms.
| 1. | Constant
current charge: The battery voltage gradually rises by charging at a
constant current setting. If charging current and time are not managed
correctly, the battery may be overcharged. Therefore, stop charging
after confirming the completion of charging. | –
| General charge: Charging the battery for a long time with low current |
| –
| Quick charge: Charging the battery for a short time with high current |
|
| 2. | Constant voltage charge: The battery charging current gradually reduces by charging at a constant voltage setting. |
If
the battery is charged directly at the battery terminals on vehicles
with battery sensor, misinterpretations of battery condition may occur,
and under certain circumstances, unwanted 'Check Control' message or
faulty memory can be prompted. When recharging is finished, let the battery stand for over 10 hours at normal temperature for battery stabilization. |
Battery Voltage and Status
Check the battery voltage and status by using a battery tester.
Battery Terminal
| 1. | Move back and forth to check if the battery terminals (A) are loose or corroded. Clean any corroded terminals.
If
the battery positive connection is loose, disconnect the ground (GND)
cable first before attempting to remove or tighten the positive
connection to prevent personal injury. |
| 2. | If the battery clamp on positive (+) battery terminal is not seated securely: | (1) | Turn ignition switch OFF and disconnect the negative (-) battery terminal. |
| (2) | Tighten battery clamp (A) on positive (+) battery terminal.
Positive (+) battery terminal:
7.8 - 9.8 N·m (0.8 - 1.0 kgf·m, 5.8 - 7.2 lb·ft) |
|
|
| 3. | If the battery clamp on negative (-) battery terminal is not seated securely: | (1) | Tighten battery clamp (A) on negative (-) battery terminal.
Negative (-) battery terminal:
4.0 - 6.0 N·m (0.4 - 0.6 kgf·m, 3.0 - 4.4 lb·ft) |
|
|

In case the battery is reset, connect the battery cable again, and then
start the engine or turn the ignition switch ON for more than 10
seconds. Repeat the procedure from No. 1. To prevent the battery from being reset during the inspection, |
| 1) | Connect a jump cable between the battery (-) terminal and the ground cable. |
| 2) | Disconnect the ground cable from the battery (-) terminal. |
| 3) | Connect an ammeter between the battery (-) terminal and the ground cable. |
| 4) | After disconnecting the jump cable, read the current value of the ammeter. |
|
 |
| 5. | Read the current value of the ammeter. | •
| If
the parasitic current is over the limit value, search for abnormal
circuit by removing a fuse one by one and checking the parasitic
current. |
| •
| Reconnect
only the fuse suspected of parasitic current and search for the
problematic unit by removing the components connected to the circuit one
by one until the parasitic draw drops below limit value. |
Limit value (after 10 - 20 min.) : Below 50mA |
|
[Using a Clamp type Ammeter]

| 2. | Close all doors except the engine hood, and then lock all doors. | (1) | Disconnect the hood switch connector. |
| (3) | Close the doors or remove the door switches. |
|
| 3. | Wait a few minutes until the vehicle’s electrical systems go to sleep mode. | •
| For
an accurate measurement of a vehicle parasitic current, all electrical
systems should be in sleep mode. (It takes at least one hour or at most
one day.) However, an approximate vehicle parasitic current can be
measured after 10 - 20 minutes. |
|
|
| 4. | Install a clamp type ammeter to negative (-) battery terminal.
 |
| 5. | Read the current value of the ammeter. | •
| If
the parasitic current is over the limit value, search for abnormal
circuit by removing a fuse one by one and checking the parasitic
current. |
| •
| Reconnect
only the fuse suspected of parasitic current and search for the
problematic unit by removing the components connected to the circuit one
by one until the parasitic draw drops below limit value. |
Limit value (after 10 - 20 min.) : Below 50mA |
|
By using the Micro 570 Analyzer, the charging and starting systems including the battery, starter and alternator can be tested.
| •
| Due
to the possibility of personal injury, always take extreme caution and

[Charging and Retesting after charging battery]
Charging battery
Set battery charger to ‘Auto Mode’ (the Mode that
charging current drops as the battery charges) and charge battery until
charging current drops down close to zero or the charger alerts with an
alarm when charging is complete. (Minimum charging time recommended: More than 3 hours in Auto Mode explained above) | •
| If
battery is not fully charged, battery surface voltage will be high
while the amount of current charged (CCA) in battery is low. If the
battery is tested in this condition, the tester may misjudge that
battery sulfation has occurred as the level of current in battery is too
low in comparison with battery voltage. * Surface voltage:
When battery is charged, electrolyte temperature increases and chemical
reaction becomes active resulting in an excessive increase in battery
voltage. It is known that it takes approximate one day to subside this increased surface voltage completely. |
Testing battery after charging
Do not test the battery immediately after charging.
Test the battery after the battery surface voltage has subsided as
instructed in the following procedure. | (1) | When battery charging is complete, install the battery to the vehicle. |
| (2) | Turn IG ON, turn on the headlamps at low beam, and wait for 5 minutes. (Discharge for 5 minutes.) |

[Charging and Retesting after charging battery]
Charging battery
Set battery charger to ‘Auto Mode’ (the Mode that
charging current drops as the battery charges) and charge battery until
charging current drops down close to zero or the charger alerts with an
alarm when charging is complete. (Minimum charging time recommended:
More than 3 hours in Auto Mode explained above) | •
| If
battery is not fully charged, battery surface voltage will be high
while the amount of current charged (CCA) in battery is low. If the
battery is tested in this condition, the tester may misjudge that
battery sulfation has occurred as the level of current in battery is too
low in comparison with battery voltage. * Surface voltage:
When battery is charged, electrolyte temperature increases and chemical
reaction becomes active resulting in an excessive increase in battery
voltage. It is known that it takes approximate one day to subside this increased surface voltage completely. |
Testing battery after charging
Do not test the battery immediately after charging.
Test the battery after the battery surface voltage has subsided as
instructed in the following procedure. | (1) | When battery charging is complete, install the battery to the vehicle. |
| (2) | Turn IG ON, turn on the headlamps at low beam, and wait for 5 minutes. (Discharge for 5 minutes.) |
| (3) | Turn off the headlamps at IG ON, and wait for 5 minutes. (Wait for 5 minutes.) |
| (4) | Remove +, - cables from the battery and test battery. |
| •
| For an in-vehicle test, the display alternates between the test results and the message “PRESS FOR STARTER TEST. |
|
| •
| Before
starting the test, inspect the alternator drive belt. A belt that is
glazed or worn, or lacks the proper tension, will prevent the engine
from achieving the rpm levels needed for the test. |
|
|
| 8. | Press the ENTER button to proceed with the starter test.
 |
| 9. | Start the engine when prompted.
 |
| 10. | The tester displays the status of the starter system, cranking voltage, and cranking time in milliseconds.

Remedy
| NO PROBLEMS
| System is showing normal output from the alternator.
| NO OUTPUT
| No alternator output detected.
| –
| Check
all connections to and from the alternator, especially the connection
to the battery. If the connection is loose or heavily corroded, clean or
replace the cable and retest. |
| –
| If
the belts and connections are in good working condition, replace the
alternator. (Older vehicles use external voltage regulators, which may
require replacement of the voltage regulator only.) |
| LOW OUTPUT
| Alternator does not supply charging current to battery and electrical load to system fully.
| –
| Check belts and alternator and replace as necessary. |
| HIGH OUTPUT
| The voltage from alternator to battery is higher than normal limit during voltage regulation.
| –
| Check connection and ground and replace regulator as necessary. |
| –
| Check electrolyte level in the battery. |
| EXCESSIVE RIPPLE
| The voltage from alternator to battery is higher than normal limit during voltage regulation.
| –
| Check alternator mounting and belts and replace as necessary. |
| CHARGE BATTERY
| The starter voltage is low and the battery is discharged. Fully charge the battery and repeat the starter system test.
| REPLACE BATTERY
| Battery must be replaced before the starting system can be tested.
|
|
| 19. | Press the BACK/PRINT button to print the test results or MENU to return to the Options Menu. |
| 1. | Make sure that the ignition switch and all accessories are turned OFF. |
| 2. | Disconnect the battery cables (negative first). |
| 3. | Remove the battery from the vehicle. | •
| Care should be taken in the event the battery case is cracked or leaking, to protect your skin from the electrolyte. Heavy duty rubber gloves (not the household type) should be worn when removing the battery. |
|
 |
| 4. | Inspect
the battery tray for damage caused by the loss of electrolyte. If acid
damage is present, it will benecessary to clean the are a with a
solution of clean warm water and baking soda. Scrub the area with a
stiff brush and wipe off with a cloth moistened with baking soda and
water |
| 5. | Clean the top of the battery with the same solution as described above. |
| 6. | Inspect the battery case and cover for cracks. If cracks are present, the battery must be replaced. |
| 7. | Clean the battery posts with a suitable battery post tool. |
| 8. | Clean
the inside surface of the terminal clamps with a suitable battery
cleaning tool. Replace damaged or frayed cables and broken terminal
clamps. |
| 9. | Install the battery in the vehicle. |
| 10. | Connect the cable terminals to the battery post, making sure tops of the terminals are flush with the tops of the posts . |
| 11. | Tighten the terminal nuts securely. |
| 12. | Coat all connections with light mineral grease after tightening. | •
| When
batteries are being charged, an explosive gas forms beneath the cover
of each cell. Do not smoke near batteries being charged or
which have recently been charged. Do not break live circuit at the
terminals of batteries being charged. A spark will occur when the circuit is broken. Keep open flames away from battery. |
