Marine Battery question...

[hollowpoint 10+ year member]

My question is would a marine battery such as the Blue Top work in a car properly? It basically combines the yellowtop and redtop together, but would it be a good choice to get and use for a Jeep Cherokee with a 117alt possibly going to having 900watts running soon. So what are your thoughts?

yes and from what i read the only difference is the blue tops have stainless steal terminals to resist corrosion from the salt water

not really worth the extra money for a car. We have one in our boat, but mainly the terminals are different. Just put yellow under the hood, its more than enough.

I kind of was wondering the same thing, where I work we get marine batteries that warrentee out sometimes and after we put a good charge on them and let them sit a couple of days they test good. would it be worth it to pick one up? usually they test bad because they have a low charge on them.

Thats interesting. I looked on a site that sold them and on Optimas site. Basically it looks like its a mix of Red Top(Better for starting) and Yellowtop(better for deep cell). The blue top was discribed to be combined atleast thats how I took it in and on the one site that sold them costed the same as a YellowTop. It really isnt worth it to spend the same on something that has both qualites?

hasa68mustang brought another question to my mind...if it is a deep cell battery why would it test bad to having a low charge?

Im just trying to understand more about the electrical stuff of audio as well as be a smart buyer if you know what I mean..

The blue top is the same battery as the yellow top except it has a second set of stud terminals. It is perfectly fine to run one underhood or as a second battery.

Oh ok thats good to know...but with those 2nd terminals would it be easier to run an amp to them compared to other set that is already hooked up?

you can get the yellow top with the same terminals as the blue..there is no difference...

i actually just use the stud and wing-nut..alot easier than messing with the post imo..

They are really the same? I looked at the charts comparing and the blue has more cranking amps...would that effect anything?

more amps the better

I have no Idea... After I shorted mine out *oops* lol it went dead overnight... as in open the door and no lights would turn on... I Was pretty pissed as I thought the battery was bad, AND ontop of that I learned a lesson... anytime you are working on a car disconnect the negative terminal... I was running my nitrous line under the car and the line flipped in the compartment and managed to end up ontop of the positive terminal... and it was originally in the back of the compartment... I welded my nitrous line ot the battery, and it ended up putting a hole in it so I have to fix that and THOUGHT I lost a battery, took it to work, immediately tested bad. I put it on my charger for a few hours... tested good and is still fully charged so Im pretty happy... maybe our battery tester/charger just sucks... lol but im not complaining...
