Always disconnect the negative cable first and hook it up last to avoid accidentally shorting the battery. To check the battery state of charge, look at the indicator eye on top of the battery. A green eye indicates 75 to 100 percent charge, a black eye indicates 0 to 75 percent charge, and a clear eye indicates low electrolyte level. If the battery is maintenance-free and the eye is clear, replace the battery. If it has removable cell caps, add enough water to bring it to the correct level. Perform an open-voltage circuit test using a voltmeter to check the battery's voltage, which should be at least 12.4 volts. Charge the battery if necessary. Perform a battery load test using a battery load tester to evaluate its ability to operate the starter and accessories under heavy load. Connect the tester and apply a load of 50 percent of the cold cranking amperage rating for a maximum of 15 seconds. The battery voltage should not drop below 9.6 volts. If the battery is weak or defective, the tester will indicate this. To replace the battery, remove the spare tire access cover, disconnect the negative cable, remove the battery retention strap, disconnect the vent tube, remove the hold-down bolt and clamp, and lift out the battery. Inspect and clean the tray and surrounding metal if necessary. Install the new battery following the reverse of the removal steps. To replace the battery tray, remove the battery, detach the Power Distribution Center, remove the mounting bolts, and remove the tray. Install the new tray following the reverse of the removal steps.

Use a memory-saver device to maintain power for systems like the alarm and door locks. Disconnect the IBS connector before disconnecting the cable from the negative battery terminal. After reconnecting, recalibrate systems like the window express-up/down, sunroof, and ESP Steering Angle Sensor. Always disconnect the negative terminal first and reconnect it last to prevent shorting.

Battery maintenance is vital for vehicle reliability. Always turn off the engine and disconnect the negative battery cable before servicing. Avoid sparks, smoking, or open flames near the battery due to its flammable hydrogen gas emission. Handle the corrosive battery electrolyte carefully to avoid contact with eyes, skin, or clothing. Wear safety glasses, gloves, and old clothes when working near the battery. Check the battery for corrosion, loose connections, cracks, and damaged clamps or cables. Clean cable clamps, terminals, and the battery top with warm water and baking soda. Ensure the battery tray and clamp fasteners are in good condition, and reinstall the battery securely. Cover any corrosion damage on metal vehicle parts with zinc-based primer and paint. Use a slow-rate charger for restoring a deeply discharged battery or maintaining the charge in seldom driven vehicles. Avoid rapid boost charges that may damage batteries.

If corrosion is present, especially around the terminals, the battery should be removed for cleaning. Thoroughly clean cable clamps, terminals, and the battery top with a solution of warm water and baking soda, taking precautions to avoid contact with your eyes, hands, or clothes.

Perform a battery load test using a battery load tester to evaluate its ability to operate the starter and accessories under heavy load. Connect the tester and apply a load of 50 percent of the cold cranking amperage rating for a maximum of 15 seconds. The battery voltage should not drop below 9.6 volts.

Before removing the battery, you should remove the spare tire access cover and disconnect the vent tube from the battery.

It's important to wear safety glasses, protective gloves, and old clothes while working around the battery. The battery's electrolyte contains harmful sulfuric acid, and safety gear helps protect against potential contact.

Look at the indicator eye on the top of the battery (if equipped). A green indicator eye means the battery is 75 to 100 percent charged, black indicates 0 to 75 percent charged, and clear or bright indicates low electrolyte level. Maintenance-free batteries with clear indicator eyes should be replaced, while low-maintenance batteries with removable cell caps can have distilled water added to the correct level. Perform an open-voltage circuit test using a voltmeter to check the battery voltage, ensuring the surface charge is removed for accurate measurement. A fully charged battery should have at least 12.4 volts. Charge the battery if the voltage is lower. Perform a battery load test with a battery load tester to assess the battery's ability to handle heavy amperage draw. A fully functional battery should not drop below 9.6 volts during the test.
