The battery is located in the front of the engine on the driver's side. It is encased in a black plastic box that is held in place by a bar that looks like some kind of brace for the front end of the Trailblazer. Remove the bolts holding the long black bar on top of the black plastic casing. The battery is inside. Remove the cables from the battery. Lift up on the battery to remove. Find a battery the same size that has at least the same number of CCA (Cold Cranking Amps). Then reverse the process to install the new battery. Good luck!
