These instructions apply to the Dodge Charger LX (2006-2010). For other models, please choose your vehicle here.
The Dodge Charger LX (2006–2010) mounts its main battery in the trunk, but also provides remote terminals under the hood for jump-starting and charging. Whether you’re replacing the battery, working on electrical components, or storing the vehicle, it’s important to disconnect and reconnect the battery safely to avoid electrical damage.
Before You Start
- Park on a flat surface, switch ignition OFF, and remove the key.
- Wait at least 3 minutes before disconnecting to allow control modules to power down.
- Have a 10 mm wrench or socket ready for the battery clamps.
- Wear gloves and safety glasses.
Battery Location
- The main battery is located inside the trunk, under the floor cover on the right-hand side.
- For quick charging or jump-starting the Dodge Charger LX (2006–2010), use the remote positive (+) post and engine/body ground (–) under the hood instead of accessing the trunk battery.
How to Disconnect the Battery
- Open the trunk and remove the floor panel to access the battery.
- Using a 10 mm wrench, loosen the negative (–) terminal clamp first and remove it from the post.
- Next, loosen and remove the positive (+) terminal clamp.
- If replacing the battery, remove the hold-down bracket and carefully lift the battery out (it is heavy).
How to Reconnect the Battery
- Position the battery in the tray and secure it with the hold-down bracket.
- Connect the positive (+) terminal first and tighten securely.
- Then connect the negative (–) terminal and tighten.
- Check that both clamps are snug and free from corrosion.
After Reconnecting
- Reprogram radio presets and reset the clock.
- If equipped with auto-down/up windows, re-initialize them by fully lowering and raising each window while holding the switch for 2 seconds at the top.
- Drive normally to allow the PCM (engine computer) to re-learn idle and shift adaptations.
Maintenance Tips
- Keep terminals clean and apply dielectric grease or petroleum jelly to prevent corrosion.
- Batteries typically last 4–6 years; test annually after the third year.
- If the Charger repeatedly has a dead battery, check for parasitic drains or alternator issues.
