My factory subaru battery went dead about a month and a half ago. I took it to orileys(sp?) and theirtester said it was bad. So then I bought an Optima Red Top battery thinking my battery woes would be over. However, today when I went to start my car it was very slugish, then when I was trying to leave school it wouldn't even turn over. After I turned off my radio, fan, lights it was able to start but just barley.
What gives? I thought this was supposed to be a good battery... My car only has ~55k miles on it. Could the alternator be going out already?
