The battery for the 2000 Buick Lesabre is under the back seat. I stand inside the car at about the middle of the back seat. Using both hands I pull up sharply on the back seat until it comes up. Remove the seat and you'll see the battery. Changing the battery is the same procedure as any battery. Remove the negative battery clamp first, then the positive, unbolt the battery, and lift it out.

don't use a case that has a magnet..... it will drain the battery ...the back is made of metal

New batteries - charge in batteries is good (also tested under load).

 

When AC power fails, no power is supplied to PC connectors by the UPS.

 

UPS self test works fine. UPS does not report any problems via software - Power Management under Windows XP.
