How do you remove the battery from a 2001 Chevy Impala?
Just did one last week. Disconnect the battery connections. You must then remove the large black brace you see going across the battery. You also must remove the air flow tube right behind the battery. Once you remove them, release the battery hold down screw, (bottom of battery) and work the battery out. It will come out by twisting it to the left. It is a very tight fit. Reverse the procedure to install the new one.
