I've got a yellow top that just kicked the bucket after almost 3 years. The warranty on the battery was only for 1 year when I bought it. Looking at the store today I noticed the Optima's now have 3 year warranties. Has anyone had to deal with the new warranty for replacement. I've got to get a new battery tomorrow and am not wanting to throw out another $200 if it's gonna die after the warranty period. My stereo is running at 1650 RMS, but rarely used at anywhere near high volume (I know I need to upgrade the alt). I have to run the truck in a holiday parade on Sat morning, and tomorrow will be the only time I have to swap the battery out.
