How do you remove the car battery of 2001 Volvo s40?
I don't know, but I had a similar problem in a 2002. It seemed
there was a latch that was supposed to slide to let the battery out
which was latched in, but I couldn't move the latch at all. It was
very frustrating and a person from Checker Auto Parts couldn't
figure it out either.
I had similar situation, after some frustrating time trying to
figure out how to release the latch, it occurred to me that the
latch is designed to pop-out when levered upward at the tap. I used
a hammer claw to tug at the tap of the latch and pull upward with
controlled steady force, and it should pop-out.
