Step-by-Step Instructions
Follow these steps carefully
1
Prepare the vehicle
Battery: engine bay, driver side. Need: Group 94R (H7) AGM, 10mm/13mm sockets. The IBS is on the negative cable: handle it carefully, but Jeep does NOT require registration. Expect presets and windows to reset; slow Uconnect reboot is normal.
2
Disconnect negative first
Disconnect the NEGATIVE terminal first. The IBS sensor is a small module where the negative cable meets the terminal — use a 10mm wrench on the clamp. Be gentle with the IBS; don't yank the cable. Tuck it aside so it can't contact the terminal.
🔧 Mechanic's note — Ray Delgado
I've learned: be gentle with that IBS module on the negative cable — it's a small circuit board, not just a clamp. Crack it and you're buying an expensive sensor plus chasing start/stop errors for weeks.
3
Remove the hold-down
Remove the hold-down — typically a wedge clamp at the base or a bracket — with a 13mm socket. Keep the hardware and note the battery orientation. Avoid stressing the IBS wiring on the negative cable during removal.
4
Lift out the old battery
Lift the old battery straight up and out — the Group 94R is heavy (50+ lbs). Note the orientation; positive terminal position matters. Verify the replacement: most use Group 94R AGM for start/stop. Early flooded originals can upgrade to AGM; the KL's system handles both.
5
Clean the tray and terminals
Clean the tray of debris and corrosion, and the terminals with a wire brush until shiny. Inspect the IBS connector on the negative cable — it must be clean and undamaged. Check the positive cable for corrosion and ensure the tray drain is clear.
6
Install the new battery
Place the new Group 94R AGM in the tray, matching the original orientation. Reinstall the hold-down and tighten securely — the battery must not move. Ensure the IBS aligns properly with the new negative post, and double-check terminal positions.
7
Reconnect positive first
Reconnect POSITIVE first (red, plus), tightening the 10mm clamp. Then reconnect the negative with the IBS — ensure the module seats properly on the post and the connector is secure. Apply dielectric grease to both terminals. No registration needed. Don't pinch the IBS wiring.
8
Verify and complete
Close the hood and start. Expect: radio presets lost, windows may need relearn (hold switch up/down a few seconds), Uconnect may take a minute or two to boot. Start/stop may lag — the IBS needs a few drive cycles. No warning lights should remain.
All Done!
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
⚠️ Common Mistakes to Avoid
- • Not disconnecting the negative terminal first, which can cause a short circuit.
- • Forgetting to clean the battery terminals, leading to poor electrical contact.
- • Installing the new battery without securing it properly, causing potential movement during driving.
