How do you replace 2004 Nissan Quest battery?

Answer 1

1. Please read other answers on general battery replacement tips, since I'm just a weekend mechanic.
2. I've read there is a battery memory saving device that goes into the power outlet to retain radio, navigation memory while the battery is being changed. I didn't use one. It might be important if you have navigation or anything else that will lose important memory.
3. Spray off the white corrosive powder. Use baking soda to neutralize if necessary.
4. Spray screws with WD-40.
5. Remember it's a battery. Don't mistakenly connect the 2 terminals with a screwdriver or wrench.
6. Negative connection first. Use 10mm wrench, loosen nut and wiggle the cable loose. Use a screwdriver to pry if necessary, it may take some force to get it to budge. Just push it aside.
7. Repeat with positive connection. This is a large stiffer wire. Push it down and back underneath the air inlet tube.
8. Loosen both nuts on the hold down bar that runs left to right. They are connected to 5" long "J" screws that just hook into a hole near the bottom of the battery. It will be obvious once you lift the battery out. Just let these long screws tilt toward you, or rotate them out of the hole they're hooked into.
9. Remove the plastic "skirt" around the battery. It just lifts off but you'll have to maneuver it around some nearby items.
10. Take out the battery. It's heavy.
11. Look at the holes that the 5" long hooks fit into to, so you can find them later.
12. Put in the new battery.
13. Replace the plastic skirt around the battery.
14. Push the battery all the way to one side and hook the 5" long screw back into its hole. Put it through the hold down bar and place a nut loosely on it.
15. Repeat for the other hook screw.
16. Tighten down the hold down bar.
17. Replace and tighten positive terminal.
18. Replace and tighten negative terminal.
19. Cover terminals with Vaseline even though I think there's some real battery stuff you can use also.
20. Reprogram your radio and seat memory buttons. i hope you were smart enough to write down your favorite channels.
