They put the battery under the rear seat for a number of reason's 1 if it has air ride or side curtain air bags it requiers another fuse panel wich you will find across from it on the drivers side and that box needs raw power all the time so insted of them putting it (the fuse box ) on the firewall they utilized the space in the back seat plus its less wireing for that box apposesed to 1 long primary wire for the starter

As odd as this sounds check under the back seat. My brother has a new model Lesabre and he had to take the seat part of the back seat out to change his battery.
I can't find where the battery is and would like to know in view of the weather in PA. Also since our Buick dealer has dropped Buick, what battery do I need and the average cost.THanksJ BovaMy 2003 Buick LeSabre Custom has the battery under the rear seat. The battery is vented to the outside under the car and is about $140.00. Car manual shows how to remove rear seat. Pretty easy to do.Dougtv33
Underneath the back seat of the car. I was surprised!!
In my 2000 LeSabre, it's under the back seat. Remove the rear seat and I'll bet it's there.
