This procedure covers the removal and replacement of the 12V auxiliary battery in the 2022 Rivian EDV 500 electric delivery van.

Warnings

Tools required

Parts

• 12V auxiliary battery × 1 — Group 48 AGM battery or OEM equivalent
• Battery terminal protector spray × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Power off the vehicle completely using the power button
3. Open the hood and secure with prop rod
4. Wait at least 2 minutes after powering off to allow systems to enter sleep mode
5. If desired, connect a memory saver tool to the OBD-II port to maintain radio presets and seat memory (optional)
6. Locate the 12V battery in the engine compartment on the driver's side

Procedure

1. 1

   Disconnect negative terminal
   Using a 10mm socket, loosen the negative (-) battery terminal bolt. Remove the cable from the battery post and secure it away from the terminal to prevent accidental contact. If the cable is difficult to remove, use a battery terminal puller to avoid damaging the post.
2. 2

   Disconnect positive terminal
   Using a 10mm socket, loosen the positive (+) battery terminal bolt. Remove the cable from the battery post and position it away from the battery. Cover the positive terminal with a shop towel to prevent accidental short circuits during removal.
3. 3

   Remove battery hold-down bracket
   Locate the battery hold-down bracket securing the battery to the tray. Using an 8mm socket, remove the hold-down bolt. Lift the hold-down bracket away and set aside in a clean area.
4. 4

   Inspect battery tray mounting
   Check the battery tray bolts for looseness or corrosion. If the tray requires removal or has become loose, remove the three battery tray bolts using a 10mm socket. Clean any corrosion from the mounting surface.
5. 5

   Remove old battery
   Carefully lift the battery straight up and out of the battery tray. The battery weighs approximately 40-50 lbs. Avoid tilting excessively to prevent acid leakage if the battery is damaged. Set the old battery aside on a stable surface.
   ⚠Battery weighs 40-50 lbs. Use proper lifting technique to avoid back injury.
6. 6

   Clean battery tray and terminals
   Inspect the battery tray for corrosion, debris, or damage. Clean the tray with a wire brush and baking soda solution if corrosion is present, then rinse and dry thoroughly. Clean both battery cable terminals with a wire brush or battery terminal cleaner until bright and free of corrosion.
7. 7

   Reinstall battery tray (if removed)
   If the battery tray was removed in step 4, position it back into place and install the three battery tray bolts. Torque the bolts to specification using a torque wrench.
   Torque spec

   Battery Tray Bolts12 Nm (9 lb-ft)
8. 8

   Install new battery
   Carefully lower the new 12V battery into the battery tray, ensuring the positive and negative terminals are oriented correctly (positive terminal typically toward the front of the vehicle). Verify the battery is fully seated and level in the tray.
9. 9

   Install battery hold-down bracket
   Position the battery hold-down bracket over the battery. Install the hold-down bolt and torque to specification. Ensure the battery is secure and cannot move in the tray.
   Torque spec

   Battery Hold-Down Bolt8 Nm (6 lb-ft)
10. 10

    Connect positive terminal
    Remove the protective covering from the positive terminal. Place the positive cable terminal onto the positive battery post. Apply a small amount of dielectric grease to the connection if available. Install the positive terminal bolt and torque to specification using a torque wrench. Do not exceed the specified torque.
    ⚠Do not overtighten terminal bolts beyond 6.0 Nm (4.0 lb-ft) - this can crack the battery terminal.
    Torque spec

    Battery Terminal Bolts6 Nm (4 lb-ft)
11. 11

    Connect negative terminal
    Place the negative cable terminal onto the negative battery post. Apply a small amount of dielectric grease to the connection if available. Install the negative terminal bolt and torque to specification using a torque wrench. This will restore power to the vehicle systems.
    ℹ️Vehicle systems will power on when negative terminal is connected. Dashboard warning lights may illuminate temporarily.
    Torque spec

    Battery Terminal Bolts6 Nm (4 lb-ft)
12. 12

    Apply terminal protection
    Spray both battery terminals with battery terminal protector spray or apply a thin coating of dielectric grease to prevent future corrosion. Ensure the spray does not contact other engine components.

Reassembly

1. Close the hood and ensure it is properly latched
2. Dispose of the old battery at an appropriate recycling facility - automotive batteries contain hazardous materials and must be recycled
3. Keep the battery core receipt if applicable for core charge refund

Verification

• Press the brake pedal and power on the vehicle - all systems should initialize normally
• Verify the instrument cluster displays no battery-related warning lights after initial system check (typically 10-15 seconds)
• Check that all power accessories function correctly (windows, wipers, infotainment system)
• Verify the 12V battery voltage reads 12.6-12.8V on the vehicle display or with a multimeter with the vehicle off
• Test that the vehicle enters Ready mode normally when brake is pressed and power button is activated
• If any warning lights persist or systems do not function correctly, recheck all terminal connections and torque specifications
• Monitor the vehicle for 24-48 hours to ensure the 12V battery is charging properly from the high-voltage system
