I just replaced my battery... OBVIOUSLY needed it. Looked kind of cracked and the battery tray was corroded lol. I have a 2002 2.2L w/ about 50k on it. I didn't notice the problem till the recent cold weather hit though.
I've already replaced the battery. I'm an Autozone junkie so I got the Duralast. I spent way too much money on this time around home. But car is working fine now and I haven't had any problems with it yet. Thanks for the info everyone.
