This is just a quick review of my experience with this battery. I LOVE IT. 650 Cold Cranking Amps. More than enough so far. I got it at Pep Boys for $149.00 plus tax because they did not have the Yellow top. The best Price I have seen anywhere before or since. I do not have anything extremely exotic installed yet. Just replaceable lamp headlights 55/75 Watts and 2 130 Watt Procomp Explorer 8", a York which I will get to Shortly and a fairly power intensive stereo. The Marine Blue Top is Awesome for accessories because of the extra wing nut poles. On occasion I have a little trouble starting the truck. This is in no way a battery problem. (Except when I'm an idiot). I think these are heat related problems but I'm not sure and so far it has not been a big deal. I have had to run the starter for 20+ seconds several times in a row before it would start. I have no trouble with the battery, even when in low gear going up a steep incline. I have <font color="red">COMPLETELY</font> killed the battery on 2 seperate occasions. The first time I left the switch to the York on (before I rewired it to only turn on with the ignition) for TWO WEEKS without running the truck. I had to jump the truck from another car (this took a while) but once it (the truck) stared I left it idling for an hour or so and had no trouble after. Until...I left the head lights on for <font color="blue">Three Days</font>. Once again I jumped the truck and let it idle for an hour or so. I have since (three weeks) been using the vehicle as a daily driver and have had no problems. This Memorial Day weekend I will be using the ProComp lights even if I'm not 4 wheelin' I will leave some feed back about this next week.
