my truck is about 4.5 years old now. i have alot of accessories hooked up to it:

- 1000 W RMS amp (and 1.0 cap)
- MP3 player
- dash overlay kit
- PIAA foglamps

the truck turns over everytime with no hesitation, even in 0* weather. i am just waiting for the day when it has no life left. i want to upgrade to an optima yellow top, but want to get the most out of the stock battery. i am thinking that fall 2004 would be the best bet for a new one. just in time for winter. better to be proactive before i get stuck in the middle of nowhere

 

I've got almost 5 years on mine and no problems whatsoever. Truck starts great no matter the temperature.

 

3.5 years on my stocker. Ran it down once playing the radio while doing the seats. I'm gonna upgrade soon. The Blazer needs this battery.
