The MF(Maintenance Free) battery is, as the name implies, totally maintenance free and has no removable battery cell caps.

The MF(Maintenance Free) battery does not require water replenishment for the repair.

The battery is completely sealed, except for small vent holes in the cover.

Significantly longer service life

Increased starting reliability at low temperatures

100 % freedom from maintenance

Low risk in event of an accident (reduced risk to the environment)

IU or WU charging technique

Optimized charging voltage for IU or WU: 14.7V (at 20°C - 30°C (68°F - 86°F)) about 24 hours

Min. charging voltage at 20°C (68°F): 14.4V

Max. charging voltage at 20°C (68°F): 14.8V

10% of capacity is recommended as charging current (e.g. 60Ah : 10 = 6,0A charging current).

Turn the ignition switch OFF.

Disconnect the battery negative (-) terminal (A).

Disconnect the battery positive (+) terminal (B).

Remove the battery mounting bracket (C) after loosening the mounting bolt.

Remove the battery (D).

Remove the battery.

(Refer to Charging System - "Battery")

Remove the air cleaner.

(Refer to Engine Mechanical System - "Air Cleaner")

Disconnect the ECM Connector (A).

Remove the mounting bolts and nut, and then remove the ECM bracket assembly (B).

Remove the battery tray (A) after loosening the mounting bolts.

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 always use the AGM battery only. If flooded battery has installed, this can potentially lead to engine electrical trouble or ISG system error. • Replace same capacity of the AGM battery.

• Ensure 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. • The vehicle with the new battery must be placed in the ignition switch OFF and door closed, hood switch OFF state for at least 4 hours. • ISG system’s stabilization may take 4 hours after new battery installation. • ISG function is operates about 4 hours later and 2 times cranking by user. But first 25 times, the ISG function can operates regardless of ISG system stability for ISG function operating 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 rendered non-operational.

Constant current charge: The battery voltage gradually rises by charging with setting a constant current. If charging current and time are not managed correctly, the battery is over-charged, therefore charging should be stopped after confirming the completion of charging.

Constant voltage charge: The battery charge current is gradually reduced by charging with setting a constant voltage.

If the battery is charged directly at the battery terminals on vehicles with battery sensor, misinterpretations of battery condition and under certain circumstances also unwanted Check Control messages or fault memory entire can occur.

After recharging finished, let the battery stand for over 10 hours with normal temperature for battery stabilization.

Move back and forth to check that the battery terminals (A) are loose or corroded.If the terminals are corroded, clean them.

If battery positive connection is loose, disconnect ground(GND) cable first before attempting to remove or tighten plus connection, to prevent personal injury.

If the battery clamp on battery positive (+) terminal is not seated securely:

If the battery clamp on battery negative (-) terminal is not seated securely:

Turn the all electric devices OFF, and then turn the ignition switch OFF.

Close all doors except the engine hood, and then lock all doors.

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 go to 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.

Connect an ammeter in series between the battery (-) terminal and the ground cable, and then disconnect the clamp from the battery (-) terminal slowly.

• Be careful that the lead wires of an ammeter do not come off from the battery (-) terminal and the ground cable to prevent the battery from being reset. 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 sec. 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.

Read the current value of the ammeter.

Turn the all electric devices OFF, and then turn the ignition switch OFF.

Close all doors except the engine hood, and then lock all doors.

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 go to 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.

Install the clamp type ammerter on battery negative (-) terminal.

Read the current value of the ammeter.

※ Because of the possibility of personal injury, always use extreme caution and appropriate eye protection when working with batteries.

※ When charging battery by test result, Battery must be fully charged.

To get accurate test result, battery surface voltage must have subsided ahead before test when you test battery after charged. (See following Battery Test Results)

• Care should be taken in the event the battery case is cracked or leaking, to protect your skin from the electrolyte. Heavy rubber gloves (not the household type) should be wore when removing the battery.

Inspect the battery tray for damage caused by the loss of electrolyte. If acid damage is present, it will be necessary to clean the area 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.

Clean the top of the battery with the same solution as described above.

Inspect the battery case and cover for cracks. If cracks are present, the battery must be replaced.

Clean the battery posts with a suitable battery post tool.

Clean the inside surface of the terminal clamps with a suitable battery cleaning tool. Replace damaged or frayed cables and broken terminal clamps.

Install the battery in the vehicle.

Connect the cable terminals to the battery post, making sure tops of the terminals are flush with the tops of the posts .

Tighten the terminal nuts securely.

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.
