How Long Do Car Audio Based Batteries Last?

[Crump]

Just wondering for knowing sake. I mean if you own a car with a system in for say 75000 miles would a Ca battery still be good?

i would think it would depend on how hard you run them. but about the same as a similar non car audio battery

Old-school Yellowtops last forever

I have one that was made in 2001, it sat for 4 years in a shed with no charge on it, put it on a high voltage charge then trickle charged it for a week and it's all gravy

Like said abovedepends on how you treat them. Odysseys are warranted for 10 years :-) if you have enouh alternator power to keep your system from pulingfrom the batteries all the time, you should get 10 years or more out of them. If not they wont last as long.
