Step-by-Step Instructions
Follow these steps carefully
1
Slide the passenger seat forward to find the battery
Park the Durango on level ground, set the parking brake, and turn the ignition fully off; take the key fob away so the electronics stay asleep. Do not bother opening the hood to find the battery — on the 2011–2024 Durango it lives inside the cabin, under the front passenger seat. (The posts you see under the hood are remote jump-start terminals, handy for a jump but useless for a battery swap.) Slide the front passenger seat all the way forward on its tracks to open up the floor behind it, and look for the trim panel at the rear of the seat base.
2
Remove the trim panel and the battery cover
Remove the trim panel at the back of the passenger seat base — it is held by clips or small screws, so ease it off with a trim tool or screwdriver rather than yanking it. Behind the panel you will find a metal or plastic battery cover bolted over the battery; remove its bolts with the matching socket and lift the cover away. Lay a towel over the seat rails so dropped hardware cannot roll into the tracks, and keep every tool clear of the battery posts from here on.
3
Disconnect the negative terminal first
With the battery exposed, fit a 10mm socket on the negative (black) terminal clamp and loosen it counterclockwise, then wiggle the cable end off the post. Fold the cable aside and make sure it cannot drift back onto the terminal. Note: some Durangos with stop/start have a smaller auxiliary battery sitting near the main one — leave it completely alone. You are replacing the large main starting battery only; if you are unsure which is which, check your owner’s manual before proceeding.
🔧 Mechanic's note — Ray Delgado
That little auxiliary battery fools a lot of people — I've seen DIYers buy the wrong battery because they measured the small one. The main starting battery is the big one; if you are not sure, the manual settles it.
4
Free the positive cable and lift the battery out
Loosen the positive (red) terminal clamp the same way and slide the cable off its post, keeping it clear of the negative cable and any metal. Now unbolt the hold-down bracket that pins the battery at its base and lift it away. Grip the battery firmly with both hands and lift it straight up out of the floor well — the opening is snug and the battery is heavy, so keep it level and watch your knuckles on the seat frame. Set it upright on the ground outside the car.
5
Clean the well and the cable clamps
Scrub the inside of both cable clamps with a wire brush until bright metal shows, and check that the cable insulation is not cracked where it bends over the seat base.
🔧 Mechanic's note — Ray Delgado
I pull these clamps off and always find green fuzz where the cable bends over the seat base — flex the insulation and look for cracks there before you call it clean.
6
Seat the new battery and reconnect positive, then negative
Lower the new battery into the well in the same orientation as the old one — verify that the positive post sits under the positive cable before you set it down, because a reversed battery in this tight well is a disaster to correct. Refit the hold-down bracket and snug its bolts so the battery cannot shift under braking. Slide the positive cable onto the positive post and tighten the clamp, then fit the negative cable — negative always goes on last. Refit the battery cover and its bolts, then snap the trim panel back onto the seat base.
7
Restore the seat, start up, and verify
Slide the passenger seat back to its normal position and start the engine; it should crank strongly. Confirm the headlights, climate controls, and dashboard warnings all behave normally. Your radio presets and clock may have cleared, and the engine may idle roughly for a few minutes while the computer relearns — check your owner’s manual if a warning light stays on. Take the old battery to an auto parts store or recycler for proper disposal.
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 pry the seat instead of sliding it — the passenger seat slides fully forward on its tracks, and forcing it risks breaking the seat mechanism.
- • Dropping the battery cover bolts into the seat tracks — work over a towel and keep hardware in a tray.
- • Touching the auxiliary battery on stop/start models — you only need the main battery; leave the small second battery alone unless your manual says otherwise.
