2017 Ram 1500 - Battery Tray
The battery tray provides a point for the battery to be installed and, with the help of a battery hold down, secures the battery to prevent vibrations or motion from causing premature wear or damage. Battery trays may also include insulators to prevent leaking battery acid from reaching other areas of the engine compartment and provide provisions for securing the battery, including hook gaps or threaded fasteners, using a battery hold-down.
