my battery went dead a week ago. i took it out and went to get another one, but it didn't fit. i've been through a bunch of crap trying to get a battery that would work, and finally i have one. i just put it in, and the car wont start. it has power. the lights, stereo, and other electricals work. but when i try to crank it, it just clicks really loud and the windshield wipers come on. what happened? please help.
