i know this is dated, but wanted to toss this in for anyone who's reading about batteries..
"they (Yellow top Optima)can last over 2 times as long as a normal battery, take more of a beating, can be drained dead then charged up. they can also with stand way more shock than a normal battery up to 15 times as much for the extreme off roading or vibration that a stereo can cause, and because of their solid state can be mounted upside down, sideways or however you want. i know i've had mine dead about a dozen times and had it for about 5 years still charges and works fine.... when compared to the red top the red top isn't recommended for the deep cycle application like winches, stereos, or heavy off roading, they're more made for just reliable starting like in a nice daily driver."
Yellow is for big draw things, bunch of lights, big amps, wench, sitting around with all the lights on for hours and hours
Red is just a better built alternative to the normal battery already in your metal beast in the driveway.
Blue is the Optima Marine battery--it's for boats
