What the he// I have an 07 cc i bought in march of last year and my battery died on me after a freakin date which was awesome!!! I recently had a system installed on my truck and was wondering if the dealership would be an azz about the waranty on the battery because of it!

did you start having battery problem right after the install of the system? do you have a capacitor, if you do it might be sucking current from the battery causing a dead battery. i know this first had it happened to my frinds car with his cap and when i got it from him the issue migrated to my Tiburon and i was like WTF i had a tech at the dealer i was working at check it out and when i disconnected the cap the multimeter went way down for current draw from the battery, from like 2 amps to .00something from what i remember but that was 3 years ago.

if you have a multimeter disconnect the ground on your truck and run the meter from the neg terminal to the cable and have it set under amps to see the draw on the battery. then disconnect the cap and see if it goes down significantly, if it does thats most likely your problem otherwise the battery just might be junk and go to to dealer and see if they will give you a new one. if you do go to the dealer i would recommend you take out the subs and hide the power wire running to the cab just so they don't give you any hassle, some dealers will probably turn you down for running a system but some might not, guess its a hit or miss kinda thing.

good luck

Just found out that i also am one of the ones that have the battery issues.
Girlfriend needed to use it this morning after it had been sitting for a few days and wouldnt even turn over. I had this happen 3 times now.
What is the best fix? i heard the Optimas are a good battery. Just need a suggestion. Thanks guys.

the factory batteries are pretty damn good,especially the big one used in the big tow trucks, im at 40k on my oe and when mine dies i'll get another. like the above poster said, check your system. your normal draw should be well less than 1 amp. he said 2 amps from his system, that would kill a battery fast.

Mine is an 05 with 50k on it. Not only is the battery shot, but it's venting battery acid out the top. Truck is stock.

What's weird about the battery is I just had a red top go bad in my vette. The battery ended up rupturing on the bottom and started venting battery acid out the bottom in gas state. Red tops aren't quite as good as the rumors indicate.

I need to check mine, because when I plug my power inverter in, it beeps (which is supposed to indicate low input voltage). My multimeter took a crap, so I'm gonna check it at work. Haven't had any issues with starting, though.
