I had it for about 3 years. My optima was the same size as my original battery.
I got it because as soon as I installed my Sub and Amp my stock battery died a few weeks later so needed something made for a high powered system.
Best battery. There are times were Im at a house party and we use my car for music. Played music up loud for about 4-5 hours with engine off and would start perfectly fine the next day.
The Yellow top is made for cars with big sound systems. If you dont have one then maybe go for a redtop and save a bit of money. Red Top has good crank power for when you want to start your car.
I would go for another Yellow Top but broke at the moment. The replacement battery I got has almost the same cranking power as my optima and comes with 3 years warranty.
Should be fine with the warranty
Also, I just watched my video

And at about 0:08 you can slightly hear the vtec cross over. Nothing hardcore but if you turn it up you can hear it
