Optima yellow or red top???

yellow tops have more ah in corresponding models with the red tops. the yellows also have a lower internal resistance.

he didn't ask anything about kinetik you fanboys.

 
puting the yellow top under the hood voids the warranty, but i wouldn't care. i'd go yellow. i just got a red top. should've gone yellow.
Is that why they label it as a dual purpose battery? //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

 
they're primarily meant as a secondary battery, but i wouldn't hesitate putting it under the hood also. i got a new red top for 60$ or i would have gonje with the yellow top under the hood.

 
be different... get a blue top.

It's deep cycle like the yellow, but mainly intended for marine applications and may cost a little more.

BUT IT'S BLUE!!!

 
For main battery aplications(underhood) redtops are better. And the warranty is fine as long as you dont use it as a deep cycle battery(i.e. playing system with the car off). The red top actually discharges current faster than the yellows do.
