What leads you to believe the "battery is running low". Hard to crank on cold NE mornings??, or what..Have the batt load tested. If is OEM, and 3 years old, you may be looking at the near end of useful life. If it needs replacement, to me that's a crap shoot. There are tons of good batteries out there. Interstate is one of them, and they are reasonably priced..
