Ok, I am buying an optima. Found a local place that sells them. Both red and yellow tops.
I don't have anything that takes any amount of power. An alarm and some bizzaro electro-anti rust thingy (it was free).
Hopwever, in the summertime, I will go for long periods of running my stock stereo loud with the doors open at a campsite without running the engine.
So would the yellow be better? Or would red suffice? I do this 2 or 3 times a month at the most.
