How do I remove the chair from my Pride Mobility Jet 3 power wheel chair? The manual just have one line of description! Do I need to remove the chair before getting by hands on the battery? My Jet 3 is of an older type purchased about 5 years ago in 2004

There's a lever on the side of the chair that you disengage to unlock it. First, make sure the chair is in gear and power is off, then unplug the Joystick from the base; just follow the cable coming out of the joystick to the rear of the chair where it plugs in and rock it back and forth to unplug.
Unlock the seat with the lever, and turn the seat slightly to the left or right and lift up. Usually, it will come right off. If it's been a while since it's been removed, or if a heavier person has been bouncing atop it, it may need more coaxing. Try squirting some WD-40 at the base of the seat where the pole connects and let it run down into the shaft of the pole. Wiggle seat back and forth a bit and try lifting at the same time.

Now you can access the batteries by lifting up on the corners of the cover called the shroud. These are held on by Velcro strips so just pull up and they will give way. You will see the two batteries inside. Replace them with sealed, gel-acid deep-cycle batteried, about 32-34 amp-hour rating. Fully charge for two or three hours before using. On first uses, let the batteries discharge almost to the red zone before charging overnight. After a week, they will be well broken in. Good luck.

Was having the same problem - lift up and out just wasn't doing it. I used some liquid wrench on the post and then had my grandson lift one side while I lifted the other.
Viola!! Took two weeks to figure out it may take two people
