Hey everyone , I am new to this site and , I wanted to ask Your opinion on Optima blue top batteries . I came across a really good deal Today , in fact , it was a freebie . I was asking our battery Rep. Today about what kind of batteries He carried on His truck and , He was showing Me some of their better ones and , We got to talking about Optimas , anyway , He told Me that He took a couple in for warranty and , one of them was still good He thought ......... Well , one is good so , He gave it to me . I figure I scored big but , I got to thinking about it and , wasnt sure if it would be good to use or not . I recently bought one of the 8000 lb . Smittybilt winches and , I am about to do the GM alt. swap . So , thats the question , I really dont see much difference in the Yellow top and the blue top . Thanks in advance .

If it is good then you did score big  and there is no difference between the blue and the yellow apart from the post style. I currently have a yellow top in my Kick and will be getting a large blue top for my Sammi.

I thought the blue top was more for a marine application?

ya blue top is marine, but that battery doesn't know what its in
My buddie used to run nothing but marine battery's, they seemed to hold up just fine...other than they were bigger than the engine! haha

My understanding is that a marine battery is a deep cycle battery which essentially means you can  run it down low without damaging it where as a regular car battery can lose a cell if you run it down too low or too many times. I know that I've had regular car batterys last 10 years because I shut my lights off, close the glove box etc. where as my mother in law use to have her batterys go dead in less than  a year or two because she routinely left something on. Maybe she needed a marine battery.

Yep , Like cj said above , there is really no difference in the yellow or blue top other than the post  . They are both deep cycle and , the best thing is , it was free . I like free . I did put a trickle charge on it today and , its holding 13.3 volts , I dont have a load tester at home but , even when I checked it at work yesterday , it never dropped below 11 volts .

The blue and yellow top thing is a marketing tool.

I love Optima's  They just seem to keep on working.

If you treat your Zuk the way I treat mine with water crossings and puddle hopping, marine is a good thing.
