i've noticed that whenever i start up my TSX now, it takes a few extra cranks for it to start than it used to.

i've read on here that the OEM battery is crap, and its best to switch to something better once it dies. but is it normal for it to act like this after only 3k miles? i mean, there have been times where i've hooked up a mini-vac in the cig lighter to clean the interior, or had the music playing while cleaning the inside of my car, but this is kind of ridiculous. the temp isn't really that cold either. i think we've been averaging around 40's at night.
