hey guys, guess what, today when i was ready to go to the college my car didnt wanted to start... My battery was died, reason? i dont know, like 2 weeks ago i notice that my lights at nights suddently lost power and my cd player went off and that happens like everynight since, at mornings start the engine was difficult, but always possible, and after a while, the way home -college, the car was perfect again, only at nights when my lights and everything was on i notice the lost of power, so this morning after finally start my engine i went to buy a batt, and as usual i went crazzy and i bought a 720A batt... now i`m not sure if this new battery could do some damage to my car due to extra power... i have in my car a 600 watt amp, undercar lights, and a cd player that could be using more power than the stock one... I´m worried for nothing or my crazzy action will destroy my car? thanx
