Is there a TSB on the battery dying? I read in another thread about some one taking theirs in for a simple battery exchange. I searched the TSB's and didn't see one. I am having problems with my '07 V6 having a dead battery after sitting for a few days. Any links or advice would be great. I am running a 93 tune from Brenspeed and wondered if that may be the problem. Also, I have a massive amplifier in my trunk, but the lights don't even dim when running it. It only happens when I let it sit without starting it for a few days. Please help!

 

When I first got my car the battery died after a week. I brought it back and they put in another new one and it was fine up until 2 weeks ago. Guess they are only good for about 2 years ...

 

Mine has been fine until the weather started to get cooler. Mine is only 10 months old and has about 13k miles on it.

 

go get an Optima yellow top and an MSD 160 AMP alt

Yellow because its the deep cycle and I hearthats better for powerful stereos

 

the cold shortens battery charge

 

I have had mine for two years and haven't had a problem with it. Of couse, I drive my car at least once a week. The most I have gone without driving it is three weeks.

 

I think you're right, my original battery had to be replaced after about two and a half years. My mechanic said he was surprised it lasted as long as it did. Also,although it only happened once, my Shaker 1000 trunk thingy was "humming" after the car was turned off, causing some sort of a draw on the battery.........

Didn't we all agree it was the Shaker system dragging the battery down?
