Marine Battery. No different than any other for second underhood?

[WOT]

Hey

I was debating buying a yellow top and adding it under the hood but Im on a tight budget. My friends dad has a 1000 cranking amp BIG boat battery, made by Energizer. All it reall says is that it has 1000 marine cranking amps.

Looks like a regular 12V positive and negatie to me but I thought i should maybe check and see if it will work fine.

Im looking to add it as a second underhood battery (already have optima) and hopefully my 110amp alt can keep up with the charge lol.

Need to know its gonna work properly first though

marine batteries are usually the same as car batteries except they have an extra set terminals on top. Is it a wet cell battery? These can release hydrogen gas when charging in the vehicle IIRC.

i don't think it would hurt your electrical at all. One of my friends went to a junkyard and took 3 batteries from old cars just to give his electrical a little boost on voltage drop....

point being: its not gonna hurt to try if the battery is free //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Should be fine. We sell tons of marine deep cycles at work to people who want to use them in there RV as a secondary to run lights, accesories, etc. I don't see why it would be any different. The only downside is that the high cranking deep cycles made to start boats like the one you're getting, usually don't have as long of a reserve capacity as others, atleast not the ones we sell.

Ok cool, its brand new and it looks beefy as ****. Terminals will make it easy to add it as a second as well

I just seen 1000 MARINE cranking amp and thought it might not be good

but like said, its free, its huge, and it aint gonna hurt

Cool thanks guys.

Quick reference. I can simply ground this to my frame with 0 gauge, and run 0 gauge from the marine battery to my oem positive location and everything is good right?

"Because of the open cells with liquid electrolyte in most lead-acid batteries, overcharging with excessive charging voltages will generate oxygen and hydrogen gas by electrolysis of water, forming an explosive mix. The acid electrolyte is also corrosive."

be careful, and make sure it is mounted down properly

oem?

even if i don't know what that means i don't think that running a ground to a positive location is the...best of ideas...but maybe i'm reading that wrong.

if your running it as a second battery run the positive from your front battery to your back (marine) battery then to your amp, as for your ground run it from your frame to your marine battery to your amp

Make sure its not much more worn out thanyour YT, if it sits significantly lower it will slowly drag that battery down and cause it to die faster

Whats YT?
