I abused mine with over 1000w in audio and it lasted 3.5 years, 110F texas summers and -20F degree winters, stout battery for sure, though my optima yellow top is so much better!

 

How much "better" can a battery be? If it starts the car, and the car operates with no problems, then what difference does it make whether it is an Optima or an AutoZone special? I have seen Optimas die within 3 years and the cheapos last for 5, on cars with no extra power demands. My OEM lasted 5 years, replaced it for $100. If this one lasts 4, then it is $25 a year, or half a tank of gas.

 

stopped by autozone get some stuff and thought what the heck . . lets get battery checked . . . and my battery failed the test . . CCA were 220 . . . i guess i never added water to it and maybe its running dry . . . but i just runs fine . . im in FL btw

 

Battery may start the car until cold weather. Temperature falls below freezing. Oil is like molasses. This demands a good battery.

 

'05Z. Replaced original battery around April/May. Lasted 5yrs/31k miles.

 

I decided to stop playing the odds and put in a new battery today. ~76 months.

 

Mine just gave up the ghost on it's almost 6th birthday, 2005 with 52,000 miles. Replacing it tomorrow, looking forward to stronger starts.

 

mine just died this weekend 11/31/10
oem from my 05 350z

 

My OEM battery just died this weekend in my 06 350z 6MT stock ~53 months (350z has lived in Washington, Texas and now Louisiana - the South for most of its life). Tried to get a new pro-rated battery at dealer (25% off retail) and they insisted to have the car towed there when I physically had the battery with me. Hate dealers!! Went to Autozone and got Duralast Gold. Still won't start still troubleshooting...

 

I'm still on OEM battery. Purchased the car in august of 04... I keep a tender on it during storage.

 

**** dude my 2003 still has it's factory battery, and it is just now starting to die. It was totally fine until the car was parked for about 6 months for turbo install and other work. It still starts the car and works but if i leave the car for 4-5 days without starting it, it will hesitate pretty bad. I'll be replacing it very soon.

 

i have an 06 and 60k miles and its starting to die... i'm getting a new one in two weeks but i dont know which brand i should go for.

 

autozone duralast gold is a good replacement batt . . its a bit heavier than the stock batt but has more CCA

 

I got ~ 80k miles and 8 years out of my OEM.

 

anyone know who makes the OEM batteries?

AC Delco?

 

Kinda bummed.. Mine only lasted about 6 1/2 years 54k miles. Used the battery tender on it during the winter and everything. I wanted to cross the 7 yr mark.

I went with the AutoZone Duralast Gold. Didn't seem worth it to spend another $100 on an Optima that was 3 lbs lighter.

 

I responded to the original post in 2008, #30. I now have 38K miles and 9 years and 3 months on original battery. Amazing battery life.

 

I've got 9 years and 5 months on mine and it is still hanging on.

 

Well after 7 yrs, 30k miles, mine finally died. Went on a 2 wk trip and came back to a completely drained battery. Wouldn't even hold charge. Didn't show any signs beforehand though.

Guess I should still be happy that I got 7 yrs out of it since I rarely drive it. Replaced with duralast gold, no need for fancy optima for me

 

I got the car last year ('04 model) and the previous owner had replaced the battery with some random les schwab (i think) battery.

I already think i might be suffering from load problems, can autozone load test it whilst still on the car?

Price from Nissan for a sealed maintenance free battery is $115 including a core return.
