Dead battery - OEM battery died after less than 2 years

[AviBen]

FYI: Our OEM battery died this week just short of 2 years -- the soonest I've ever had a battery die. Although it was covered by warranty (supposedly full for 2 years, pro-rated for the 3rd year), the dealer said they'd have to determine whether anything else caused it to fail, said it would be hours before they could get to us, couldn't guarantee when they'd get us in, and then would replace it with a new OEM battery (again, just a 2-year warranty). Rather than do the song and dance with the dealer, I decided to let the very nice AAA man who jump-started us and tested the battery sell me a 7-year Die-Hard, installed from his truck in 15 minutes, with a full 3-year AAA warranty pro-rated for 7 years (AAA replaces at no cost anywhere in USA), at a cost of $114 including tax.

Yup the OEM battery is notorious for being a POS. I got about 3 and a half years out of mine.

Ditto on the battery. In both of my coupes (2008 and 2010) both didn't even last a year and a half.

I went to the dealer to complain. They had no idea why. Just slapped a new one in.

Yeah, they're junk... I got an optima red top battery.

My OEM battery has lasted me 4 years now. Lucky me

You have a 2.5. From what I've seen, its the 3.5's with a dead battery early on. I don't know why...

i got an 08 and mines still good as long as i dont purposely try and kill it.

My OEM on my '08 was completely dead last summer. I figured I left lights on, which drained before the auto turn off. It took a quick jump start, and it restarted as normal thereafter. Now, suddenly last week - same problem - completely dead, took jump start, and once again acts as good as new. WTF

PS - Now I have my Optima R35 insurance policy sitting unopened in my rear hatch!
