Step-by-Step Instructions

Follow these steps carefully

1

Open the hood and find the battery

Park on level ground, kill the engine, set the parking brake, and pop the hood. Unlike its bigger siblings, the XC40 keeps its 12V battery in the engine bay, on the passenger side, tucked under a protective cover.

2

Remove the battery cover

If space is tight, the air filter box beside it can be unclipped and moved aside so you can slide the battery out later — don't force anything; the clips release with a gentle pull.

🔧 Mechanic's note — Tom Becker

I've fixed the damage from skipping this: If space is tight, the air filter box beside it can be unclipped and moved aside so you can slide the battery out later — don't force anything; the clips release with a gentle pull.

3

Loosen and remove both cables

With a 10mm wrench or socket, loosen the nut on the negative terminal first, wiggle the cable free, and push it clear of the battery. Then do the same for the positive terminal. Negative off first — always.

4

Undo the hold-down clamp

Look for the hold-down clamp or bracket at the base of the battery tray and undo its bolt with your socket wrench. Lift the clamp out so the battery is free to move.

5

Lift the old battery out

Grip the battery on both sides and lift it straight up and out of the tray. AGM batteries are dense — expect it to be heavy — and keep it level so nothing drips onto your paint or engine components.

6

Install the new battery

Lower the new battery into the tray with the terminals oriented exactly as the old one sat — match negative to negative, positive to positive. Refit the hold-down clamp and tighten its bolt so the battery can't shift under braking.

7

Reconnect and verify

Reconnect the positive cable first and tighten the nut, then reconnect the negative cable last. Check that accessories work; radio presets, the clock, or one-touch windows may need resetting, and your owner's manual will say if this model needs a battery registration or idle relearn.

All Done!

Test your repair before closing everything up. If something doesn't work right, double-check your steps.

⚠️ Common Mistakes to Avoid

  • • Trying to slide the battery out without first moving the air filter box out of the way
  • • Forgetting the plastic battery cover, then wondering why the hood won't sit right
  • • Installing the new battery with the terminals reversed
  • • Overtightening the hold-down bolt and cracking the battery case lip
