It's usually secured with a battery hold-down clamp.
Here's a more detailed explanation:
* Open the hood: Locate the release lever in the car's cabin, usually near the driver's side door, and pull it to open the hood.
* Look for the battery: In the front of the engine compartment, on the passenger side, you should see a black rectangular box with terminals on top. That's the battery.
Tip: If you're unsure, you can always consult your 2006 Dodge Charger owner's manual for a diagram and more specific instructions.
