Step-by-Step Guide to Remove Jeep Grand Cherokee Battery
Let’s get started with the actual removal process. Remember to work in a well-ventilated area.
Step 1: Locate the Jeep Grand Cherokee Battery
As mentioned, the battery is usually in the engine bay, on the passenger side. Open your hood and visually identify the battery. It’s a rectangular box with two terminals, one positive (+) and one negative (-).
Step 2: Disconnect the Negative Terminal First
This is the most critical safety step. Always disconnect the negative (-) battery terminal first. This prevents accidental short circuits if your wrench touches the vehicle’s metal body while working on the positive terminal.
- Use your 10mm wrench to loosen the nut on the negative terminal clamp. You don’t need to remove the nut completely, just loosen it enough to slide the cable off the terminal post.
- Once loose, gently twist and pull the negative cable upwards and away from the battery terminal.
- Tuck the negative cable aside, ensuring it doesn’t accidentally touch the battery terminal or any metal parts of the Jeep.
Step 3: Disconnect the Positive Terminal
Now that the negative terminal is safely disconnected, you can proceed with the positive terminal.
- Use your 10mm wrench (or whichever size fits) to loosen the nut on the positive (+) battery terminal clamp.
- Again, you don’t need to remove the nut. Just loosen it enough to slide the cable off.
- Gently twist and pull the positive cable upwards and away from the battery terminal.
- Set the positive cable aside, ensuring it stays clear of the battery.
Step 4: Remove the Battery Hold-Down Clamp
Most Jeep Grand Cherokees have a bracket or clamp that secures the battery in place to prevent it from moving.
- Locate the hold-down clamp. This can be a metal strap with bolts at either end, or sometimes a bracket at the base of the battery.
- You may need a socket wrench with an extension to reach the bolt(s) securing the clamp.
- Carefully loosen and remove the bolt(s) holding the clamp. Keep track of these bolts, as they are small and can be easily lost.
- Once the bolts are removed, lift the hold-down clamp away from the battery.
Step 5: Remove the Battery
With the terminals disconnected and the hold-down clamp removed, the battery is now free to be lifted out.
- Caution: Car batteries are heavy! Be prepared for the weight. If you have trouble lifting, ask for assistance.
- Grip the battery firmly by its handles or sides.
- Carefully lift the battery straight up and out of the battery tray.
- Place the old battery on a stable surface, away from children and pets. It’s a good idea to place it on a piece of cardboard or wood.
Post-Removal Steps and Maintenance Tips
Once the old battery is out, there are a few more things to consider.
Cleaning the Battery Tray and Terminals
- Inspect the battery tray for any signs of corrosion or damage. Clean it with a rag and a mild cleaning solution if necessary.
- Take this opportunity to clean any corrosion from the battery cables themselves. You can use a battery terminal cleaner tool or a wire brush for this. If you have anti-corrosion spray, apply a light coating to the cleaned cable connectors.
What Jeep Grand Cherokee Battery Size is Right?
Before you install a new battery, ensure you have the correct Jeep Grand Cherokee battery size. This is often referred to by a BCI Group Number. For many Jeep Grand Cherokee models, Group Size 48 (also known as H6) or Group Size 65 are common. Always consult your owner’s manual or a reliable auto parts store to confirm the exact battery group size for your specific year and model of Jeep Grand Cherokee. Using the wrong size battery can lead to improper fit and potential damage.
Installing the New Jeep Grand Cherokee Battery
Installing the new battery is essentially the reverse of the removal process.
- Carefully place the new battery into the battery tray, ensuring it is seated correctly and facing the right direction for the cables to reach the terminals.
- Reinstall the battery hold-down clamp and secure it with its bolts. Make sure the battery is firmly held in place.
- Reconnect the positive (+) battery terminal first. Slide the clamp onto the positive terminal post and tighten the nut securely with your wrench.
- Connect the negative (-) battery terminal last. Slide the clamp onto the negative terminal post and tighten the nut.
Final Checks and Jeep Grand Cherokee Battery Jump Start
After installation, double-check that both terminals are tight and the battery is secured.
- If your Jeep Grand Cherokee was having trouble starting, you might need to perform a Jeep Grand Cherokee battery jump start if the new battery isn’t fully charged. However, if you purchased a new, pre-charged battery, it should start your vehicle without a jump.
- Start your Jeep Grand Cherokee. It should now start up smoothly with the new battery.
- You may need to reset some of your vehicle’s electronics, such as the radio presets or clock, after the battery has been disconnected.
Jeep Grand Cherokee Battery Maintenance
Proper Jeep Grand Cherokee battery maintenance can extend its lifespan.
- Keep Terminals Clean: Regularly check and clean the battery terminals for any signs of corrosion.
- Check Battery Charge: If your vehicle sits for long periods, consider using a battery tender to maintain a healthy charge.
- Avoid Deep Discharges: Try to avoid draining the battery completely by leaving lights or accessories on.
- Secure the Battery: Ensure the battery hold-down clamp is always tight. A loose battery can be damaged by vibrations.
Troubleshooting Common Issues
- Corroded Terminals: If you encounter heavy corrosion, use a dedicated battery terminal cleaner. A mixture of baking soda and water can also work, but be careful not to let it get into the battery cells.
- Stuck Terminals: If a battery cable terminal is stuck to the post, a Grand Cherokee battery removal tool (a terminal puller) is the best solution. Prying can damage the battery post or the cable.
- Battery Won’t Hold Charge: If your new battery dies quickly, there might be an issue with your Jeep’s charging system (alternator) or a parasitic drain (something drawing power when the car is off).
Frequently Asked Questions (FAQ) about Jeep Grand Cherokee Battery Removal
Q1: How often should I replace my Jeep Grand Cherokee battery?
