⚠️ Safety & Precautions

• ⚠️ Always turn the ignition OFF and remove the key before working near the battery.
• ⚠️ Batteries are heavy and contain acid; avoid tipping and keep upright.
• ⚠️ Never touch both battery terminals with metal tools at the same time to avoid sparks.
• ⚠️ Disconnect the negative (–) terminal first and reconnect it last to reduce short-circuit risk.
• ⚠️ Wear eye protection and gloves; battery acid can burn skin and eyes.
• ⚠️ Your CR-V has a battery sensor on the negative cable; handle the sensor gently and do not pry on it.

• Turn off all lights, the blower fan, and the infotainment system.
• If you have a memory saver tool, plug it into the OBD port under the dashboard to help keep radio presets and clock.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the battery

• Open the hood and look at the front left area (driver side) of the engine bay; the battery is in a plastic tray with a top bracket.
• Identify the positive (+) terminal (usually with a red cover) and the negative (–) terminal (usually black, with the battery sensor on your CR-V).
• Confirm plus and minus before loosening anything.

Step 2: Remove any covers and inspect hardware

• Use the small flathead screwdriver to gently release any clips and lift off the plastic battery cover, if equipped.
• Visually check the metal hold-down bracket and the terminal clamps so you know what needs to be loosened.

Step 3: Disconnect the negative (–) terminal

• Use the 10mm combination wrench to loosen the nut on the negative (–) terminal clamp. Turn counterclockwise just enough so the clamp can move.
• Carefully twist and lift the negative clamp straight up and off the battery post. Do not pry on the sensor housing.
• Move the cable aside so it cannot spring back onto the terminal; you can wrap the clamp with a shop towel for extra safety.

Step 4: Disconnect the positive (+) terminal

• Flip open or slide back the red plastic cover on the positive terminal.
• Use the 10mm combination wrench to loosen the nut on the positive (+) clamp.
• Lift the positive clamp straight up and off the terminal and move it aside so it does not touch metal parts.
• Keep positive cable away from any bare metal.

Step 5: Remove the battery hold-down bracket

• Locate the battery hold-down bolts at the front and/or side of the battery tray.
• Use the 12mm socket with the 3" socket extension and 1/4" drive ratchet to loosen and remove the hold-down bolts.
• Lift off the metal or plastic hold-down bracket and set it aside along with the bolts.
• Keep bolts in a small container so they’re not lost.

Step 6: Remove the old battery

• Stand centered in front of the battery and grip it with both hands by the sides or built-in handle.
• Lift the battery straight up and out of the tray. It is heavy, so lift with your legs, not your back.
• Place the old battery upright on the ground, away from the vehicle.

Step 7: Clean the tray and terminals

• Inspect the battery tray for dirt or corrosion; wipe it clean with shop towels.
• If there is white or blue corrosion on the cable clamps, use the battery terminal brush to clean the inside of each clamp until shiny metal appears.
• Lightly spray battery terminal protector spray on the clamps after cleaning, but avoid soaking the area.

Step 8: Install the new battery

• Check that the new battery’s positive (+) and negative (–) posts match the same orientation as the old one in the tray.
• Place the new battery carefully into the tray, making sure it sits flat and the posts are in the correct position.
• Install anti-corrosion battery pads over the posts if you are using them.

Step 9: Reinstall the battery hold-down

• Position the hold-down bracket over the battery.
• Install the hold-down bolts by hand a few turns to avoid cross-threading.
• Use the 12mm socket, 3" socket extension, and 1/4" drive ratchet to tighten the hold-down bolts evenly.
• Tighten until the battery is secure and cannot move, but do not crush the case. Torque to 20 Nm (15 ft-lbs).

Step 10: Connect the positive (+) terminal

• Place the positive (+) cable clamp fully down over the positive battery post.
• Use the 10mm combination wrench to tighten the clamp nut until the clamp does not move when twisted by hand. Torque to 5 Nm (4 ft-lbs).
• Close the red protective cover over the positive terminal.
• Do not overtighten; you can crack the clamp.

Step 11: Connect the negative (–) terminal

• Place the negative (–) cable clamp (with the sensor) fully down over the negative post.
• Use the 10mm combination wrench to tighten the clamp nut until the clamp is snug and does not twist. Torque to 5 Nm (4 ft-lbs).
• Make sure the sensor body is not twisted or under strain.

Step 12: Apply dielectric grease and reinstall covers

• Put a small amount of dielectric grease around the base of each terminal and clamp area to help prevent corrosion.
• Reinstall any plastic battery cover using the small flathead screwdriver if clips need to be guided back into place.
• Check one more time that all tools are removed from the engine bay.

Step 13: Start the vehicle and check operation

• Sit in the driver’s seat and turn the ignition to ON, then start the engine.
• Confirm that the engine cranks and starts normally and that warning lights behave normally after a few seconds.
• If you used a memory saver, unplug it now.

Step 14: Reset windows and clock (if needed)

• If auto up/down on windows stopped working:
  • Turn ignition to ON (engine can be running or not).
  • For each window switch: hold it down to fully lower the window, keep holding for 2 seconds, then pull it up to fully close the window and hold for 2 seconds. This resets the window auto function.
• Use the infotainment screen to reset the clock:
  • Menu > Settings > Clock (path may vary slightly) and set the correct time and date.

✅ After Repair

• Start the engine several times to confirm strong cranking and quick starts.
• Check that headlights, interior lights, wipers, and blower fan all operate normally.
• Look at the battery area with the engine running to ensure the battery is secure and cables are not rubbing on anything sharp or hot.
• Make sure no warning lights stay on in the dash; if a light stays on, switch the ignition OFF, wait a minute, then restart and recheck.
• Properly recycle the old battery at an auto parts store or recycling center; do not throw it in household trash.
