I think that I need new battery in my car and I do not know which are good.
Are DiHard gold any good?

 

Optima batteries are the only way to fly.

 

when are you suppose to change your battery?

i have a 2k with 74k . I bought it used and the battery looks stock. No real problems thus far but I don't want to find out when this thing dies on me either. Usually how long do they typically last?

just change it... you don't want it die on you when you start the car next morning i changed mine at 79k

 

mos def- worth the extra $$ for peace of mind.....particularly the deep cycle

 

Stock batteries usually last 4-5 yrs. I have a 2k and i replaced my stock at 70000.

 

I did it. I justput new battery Canadian versionn of Optima batteries from Canadian Tire. It looked good - Gel filled cells, 17 times the vibration-resistance of conventional batteries, 1000 ca, 95 min Reserve Capacity and 3 years Free Replacement Period are worth 180 Ccanadian Dolars.
My car is 2001 and has 45000 km but my battery went death - yesterday somebody had to help me to jump start my car :-[
