Battery Tray: Operation
WARNING: This page is about a different car, the 2004 Dodge Pickup and 2004 Dodge Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
The battery tray and the battery hold down hardware combine to secure and stabilize the battery in the engine compartment, which prevents battery movement during even the most extreme vehicle operation. Unrestrained battery movement during vehicle operation could result in damage to the vehicle, the battery, or both.
