Well after purchasing a 3rd battery in 1.5 years, I guess I need to have them change the alternator..... grrrrr.... I had them check/charge the battery for 5 visits. Gave up having to get jumps all the time and just replaced the battery. I couldn't find anything that looked good here in the local market so when it too died.... I suspected the battery. Now my brand new OEM replacement only lasted 2 weeks.
