If it is like the 2000 LeSabre, the rear seat will lift out and the battery is under it on the passenger side. It requires some force, but the front of the seat cushion should lift up then can be removed.

Very easy once you know how.....very hard until you do. First, lift battery up and tip to the rear. The more you tip it, the further you can lift it. You'll get to a height where the front bottom of the battery clears the box. Rotate battery sideways (clockwise) while pulling slightly rear. Tip battery up and lift out. Keep trying - this is the only way I know.
There is a fuse box under the hood and also underneath the rear seat of the veh near the battery. You can lift the seat right up. I hope this helps
The battery is located under the rear seat cushion on your 2001 Buick Lesabre.
