Model type description

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.

Description and operation
Description
1.
The MF (Maintenance Free) battery is, as the name implies, totally maintenance free and has no removable battery cell caps.
2.
The MF (Maintenance Free) battery does not require water replenishment for the repair.
3.
The battery is completely sealed, except for small vent holes in the cover.

   
After disconnecting then reconnecting the battery negative cable, reset some parts that require the reset procedures.
(Refer to Body Electrical System - "General Information")
[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.
Repair procedures
Removal
Battery
1.
Turn the ignition switch OFF.
2.

(Refer to Engine Control / Fuel System - "Engine Control Module (ECM)")
3.
Remove the battery tray (A) after loosening the mounting bolts.
Battery tray mounting bolt :
8.8 - 13.7 N·m (0.9 - 1.4 kgf·m, 6.5 - 10.3 lb·ft)

Installation
1.
Install in the reverse order of removal.
   
When installing the battery, fix the mounting bracket on the tray correctly.
   
After disconnecting then reconnecting the battery negative cable, reset some parts that require the reset procedures.
(Refer to Body Electrical System - "General Information")
   
When installing the battery, fix the mounting bracket on the tray correctly.
   
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.
Adjustment
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.
Inspection
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)

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
