🔧 Cherokee - Battery Replacement

You’ll remove the old 12V battery and install a new one, then reconnect the cables in the correct order so the Cherokee’s electronics stay safe. A weak battery can cause slow cranking, warning lights, and random electrical glitches.

Difficulty Level: Beginner | Estimated Time: 0.5-1.0 hours

Assumption: Battery is in the engine bay under a plastic cover (most Cherokees).

⚠️ Safety & Precautions

• ⚠️ Wear eye protection; batteries can vent acid and gas.
• ⚠️ Keep sparks/flames away; battery gas is flammable.
• ⚠️ Remove the negative (-) cable first and install it last to prevent accidental short circuits.
• ⚠️ Do not pull on the wires; only handle the cable ends.
• ⚠️ Battery disconnect is recommended for this job; expect clock/radio presets to reset.

📋 Before You Begin

• Park on level ground, shift to P, and set the parking brake.
• Turn the ignition fully OFF and remove the key/fob from the vehicle.
• Open the hood and let the engine bay cool down if it’s hot.
• If you use a “memory saver,” it’s a device that keeps radio settings; skip it if you’re new.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the battery

• Open the hood and locate the battery and its plastic cover.
• Remove any cover/ducting clips using a trim clip tool.
• Loosen any cover fasteners using a 10mm socket and 3/8" ratchet, then lift the cover off.

Step 2: Disconnect the negative (-) cable first

• Use a 10mm socket with a 3/8" ratchet to loosen the negative terminal clamp nut.
• Lift the negative clamp off the battery post and move it aside so it cannot spring back.
• Tip: Tuck the cable behind a safe bracket.

Step 3: Disconnect the positive (+) cable

• Flip up/remove the red protective cap on the positive terminal.
• Use a 10mm socket with a 3/8" ratchet to loosen the positive terminal clamp nut.
• Lift the positive clamp off the battery post and position it away from the battery.

Step 4: Remove the battery hold-down

• Locate the hold-down clamp at the battery base.
• Use a 13mm socket, 6" extension, and 3/8" ratchet to remove the hold-down bolt.
• Remove the clamp and set it aside.

Step 5: Remove the old battery

• Lift the battery straight up and out. Batteries are heavy—use proper lifting technique.
• If there’s no handle, grip the battery case firmly from both sides.

Step 6: Clean the terminals and tray

• Inspect the tray for corrosion (white/green crust).
• Use a battery terminal brush to clean the inside of both cable clamps.
• Spray a light coat of battery terminal anti-corrosion spray after cleaning.

Step 7: Install the new battery and secure it

• Place the new battery into the tray in the same orientation as the old one.
• Reinstall the hold-down clamp and bolt using a 13mm socket, extension, and ratchet.
• Tighten with a torque wrench: Torque to 9 Nm (80 in-lbs).

Step 8: Reconnect cables (positive first, negative last)

• Install felt washers if you’re using them.
• Install the positive (+) clamp first and tighten using a 10mm socket.
• Tighten with a torque wrench: Torque to 5 Nm (44 in-lbs).
• Install the negative (-) clamp last and tighten using a 10mm socket.
• Tighten with a torque wrench: Torque to 5 Nm (44 in-lbs).

Step 9: Reinstall covers and final check

• Reinstall the battery cover/ducting using a 10mm socket and any clips with a trim clip tool.
• Use a digital multimeter to check battery voltage with engine OFF (about 12.4-12.7V is typical for a healthy, charged battery).

✅ After Repair

• Start the engine and confirm it cranks strongly and starts normally.
• With the engine running, check charging voltage with a digital multimeter (often ~13.5-14.7V).
• Reset the clock and radio presets if needed.
• If the auto-up window feature acts weird: fully lower the window, then fully raise it and hold the switch up for 2 seconds.
• Make sure no battery warning lights stay on after a short drive.
