2019-2026 Ram 2500 & 3500 Cummins Passenger Battery Tray Diagnosis & Replacement

Symptoms of a Failing Battery Tray

A battery tray failure is a physical breakdown of the part itself. While the tray has no electrical components, its failure can lead to a host of confusing electrical issues because it allows the battery to move, shift, or vibrate excessively. Many symptoms of a bad battery tray are identical to those of a failing battery, alternator, or loose cables.

• Visible Damage or Loose Battery: The most obvious sign is a cracked, broken, or severely corroded tray. You may be able to physically move the battery by hand, or you might hear it thumping in the engine bay while driving.
• No-Start or Slow Cranking: If the battery shifts, its heavy cables can be tugged, loosening the terminal connections. This can result in a single click or rapid clicking when you try to start the engine, mimicking a dead battery.
• Flickering Lights and Electrical Glitches: A momentary loss of connection from a shifting battery can cause headlights to dim, interior lights to flicker, or the radio to cut out. On modern Ram trucks, this can also trigger random error messages on the dashboard or cause features like heated seats or the backup camera to disappear temporarily.
• Premature Battery Failure: Constant, excessive vibration from a loose mounting can damage the battery's internal plates, leading to a shortened lifespan. A swollen or bulging battery case can be a sign of this internal damage.
• Corrosion or Acid Damage: While battery leaks can cause the tray to fail, a cracked tray that allows the battery to tilt or vibrate can also contribute to leaks. You may see white or blue-green powder on the battery terminals or signs of acid eating away at the tray and surrounding metal.

Known Issues, TSBs, and Recalls

As of early 2026, there are no specific recalls or widespread Technical Service Bulletins (TSBs) from Ram or the NHTSA directly concerning the passenger-side battery tray for the 2019-2026 Ram 2500 or 2019-2024 Ram 3500. Failures are typically isolated incidents resulting from physical damage, battery acid leaks, or stress from vibration over time.

However, it is worth noting that many electrical symptoms that might be blamed on a battery issue could be related to other components. For example, TSB 08-006-23 was issued for some 2022 models for a no-start condition caused by a poor connection at the starter, which presents symptoms very similar to a loose battery terminal. Always inspect the battery's stability in its tray before replacing more expensive components.

Buying a Used Battery Tray: What to Check

A used OEM battery tray is an excellent, cost-effective option, as it retains the original fit and material quality. Since this is a simple structural part, a thorough visual inspection is all you need to get a perfectly good component.

• Check for Cracks: This is the most critical inspection. Pay close attention to the mounting holes and the corners where stress is highest. Flex the tray slightly in your hands to reveal any hairline cracks that might not be immediately visible.
• Inspect for Warping: Lay the tray on a flat surface. It should sit flat without any significant rocking or bowing. A warped tray can be difficult to install and may not hold the battery securely.
• Look for Chemical Damage: Check for any areas that look melted, chalky, or brittle. This indicates exposure to battery acid or other chemicals. A heavily damaged area is a weak point that is likely to fail.
• Verify the Part Number: Ensure the part is 68350658AC or its predecessors, 68350658AA or 68350658AB, to guarantee correct fitment for your Cummins-equipped truck.

Installation Guide

Replacing the passenger-side battery tray is a straightforward job that most DIY mechanics can handle with basic tools.

• Difficulty: 2/5 (Easy to Moderate)
• Estimated Time: 45-60 minutes
• Tools Required: Ratchet with extensions, 10mm socket (for battery terminals and hold-down), 13mm socket (for cross-brace), battery terminal cleaner.

Step-by-Step Walkthrough: 🎬 Watch: A complete guide to changing batteries on 2019+ Ram HD trucks.

1. Disconnect the Batteries: Always start by disconnecting the negative terminals on BOTH batteries to prevent short circuits.
2. Remove Cross-Brace: Use a 13mm socket to remove the engine bay cross-brace that runs over the passenger-side battery. This will give you clear access.
3. Remove the Battery: Use a 10mm socket or wrench to loosen the battery terminals (negative first), then remove the battery hold-down clamp at the base of the battery. Lift the heavy battery out of the tray.
4. Unbolt the Old Tray: Locate the bolts securing the tray to the vehicle's chassis. Remove them and take out the old tray.
5. Clean the Area: Now is a good time to clean the area underneath the tray, neutralizing any spilled battery acid with a baking soda and water solution if necessary.
6. Install the New Tray: Bolt the new or used OEM tray into place, ensuring it is seated correctly.
7. Re-install Battery and Brace: Place the battery back into the new tray, secure it with the hold-down clamp (do not overtighten), and re-install the cross-brace.
8. Reconnect Batteries: Reconnect the battery terminals, starting with the positive side.
